SUMMARY

The purpose of this study was to evaluate the loadings on the water quality of Corpus Christi Bay which could be attributable to urban runoff. Water quality and quantity models previously developed were utilized and applied to the study area. These models predict the storm runoff hydrograph for a given rainfall and the concentration of 13 different water quality parameters at selected time intervals during the storm.

The runoff model was used to predict storm runoff for comparison with actual flow data for the gaging station on Oso Creek. Good results were obtained for two different storm events. The models were then applied to the remaining urban subareas using a ’’maximum” storm of 2.10 inches and the "average” storm of 0.48 inches over a six hour period. Results indicate the strength of the pollution found in urban runoff is somewhat less than the strength of untreated municipal wastewater for Corpus Christi, Texas. However, the loads from the runoff are significant and should be recognized as a source of pollution.

INTRODUCTION

The increase of urban development in the United States has magnified the importance of considering areal sources as contributors to the deterioration of the quality of the nation’s waters. Although the advance of technology has hurdled some of the problems from point source water pollution (industrial and municipality effluents), the task of cleaning the effluents of sidewalks, streets, gutters, and storm sewers has presented an unanswered challenge to urban planners, hydrologists, engineers, and moreover, the citizens who ultimately desire and pay for better water quality.

The effect of non-point source such as agricultural and urban runoff, on the quality of a water body can be potentially greater than the effect from industrial or municipal effluents. Urban runoff can contribute a variety of problems, such as direct pollution of receiving waters, impairment of sewer and catch basin functions and overloading of treatment facilities which were not designed to handle the sporadic but tremendous volumes of water from urban runoff (Sartor 1972).

Clearly the mandate of the people is expressed in the recently enacted 1972 Amendments to the Federal Water Pollution Control Act.

Section 305 (b)(1)(E) states: Each state shall prepare and submit to the Administrator by January 1, 1975, and shall bring up to date each year thereafter, a report which shall include a description of the nature and extent of non-point sources of pollutants, and recommendations as to the programs which must be undertaken to control each category of such sources, including an estimate of the costs of implementing such programs (Grad 1973). The need to consider non-point source contributions to the pollutional load on the waters is paramount if we are to achieve the water quality desired by the citizens of the country.

In order to evaluate the loading on water quality attributable to non-point sources in the Texas Coastal Zone, it was decided to consider and evaluate those constituents of urban runoff that affect the quality of water in the Corpus Christi, Texas area.

LITERATURE REVIEW

In reviewing the literature, it was apparent that most of the work in this area was relatively recent as compared with the history of municipal and industrial water pollution control. The problems of determining the effects of urban runoff on the quality of a receiving water can only be solved when the types and quantities of pollutants are known. The solution to the problem can be developed by applying a specific methodology established by others but modified to describe the problem area. The pollutional loading can be separated into two aspects, namely the hydrology of urban runoff and the constituents of the urban runoff.

On the subject of hydrology most studies concerning urban runoff dealt with the problem of flood control and storm sewer design. Some of those studies show the hydrograph technique as a method of determining the time history of the flow created by rainfall-runoff relationships (Tholin 1959) (Espey, et al. 1966). The effect of non-uniform areal distribution of rainfall upon the flow hydrographs was discussed by Tholin (Tholin 1959).

However, Espey, et al. (1966) showed that as a watershed becomes urbanized the amount of runoff is increased.

Several factors must be considered in determining urban runoff. Runoff is that portion of rainfall which neither evaporates, nor percolates into the ground (Water Quality Management 1964). Runoff is dependent upon temperature, storm intensity, infiltration rate, vegetation, soil moisture index, topography, previous or antecedent dry period, and land development (Liefeste and Lansford 1968). If each facet of the runoff definition is considered separately, then a better understanding of runoff can be obtained

The effects of temperature on runoff include rates of evaporation of the runoff as it proceeds to the receiving waters. Or in the case of winter thaws, the amount of snow melt would depend in part on temperature. t Clearly strom intensity affects the amount of runoff. Rainfall intensity data can be obtained from rain gage information. Tokarski (1970) utilized average rainfall intensity adjusted to obtain "effective” rainfall intensity which might be expected to produce surface runoff. Infiltration rates are dependent on the soil type and surface conditions. Studies should be made from local or regional rainfall statistics, as to the probability of heavy rainfall or frozen ground (Tholin 1959).

Vegetation may affect runoff in several ways: (1) the lack of vegetation may permit a larger amount of water to infiltrate the soil; and (2) the soil will have a higher moisture content because of the lack of vegetation demands resulting in a higher rate of surface runoff (Tokarski 1970).

The soil moisture index is related to antecedent rainfall and type of soil as well as amount of vegetation. A formula to determine the soil moisture index based on antecedent rainfall, precipitation at that moment, and the time since last rainfall was developed by Linsley (Linsley, et al. 1958).

Consideration of the topography and land development is essential in determinations of runoff. The amount of impervious cover will dramatically affect the amount of runoff (Espey, et al. 1966). Each of the points mentioned above needs consideration in ascertaining the amount of runoff from a rainfall event.

Selection of a method for determining runoff is dependent upon three basic functions: (1) applicability to the area of concern - which depends on the characteristics of the particular area and the assumptions from which the method was developed;

(2) the type and amount of data available - which refers to the length, detail and completeness of the hydrologic records, and may include precipitation and streamflow; (3) the detail and accuracy required in the final answer - which may be limited by cost and any assumptions of the method applied (Merritt 1968).

One method for determining runoff is the Rational Method described in Equation (1):

Q = CIA

CD

in which: Q = Peak discharge, cubic feet per second C = Runoff coefficient I = Rainfall intensity, inches per hour A = Drainage area, acres

Several assumptions exist for the application of this method, namely the coefficient of runoff remains constant for all storms on a given watershed. This assumption has received criticism because all the complex factors that affect runoff are combined into a single coefficient (Merritt 1968). Still the formula is applicable for fast, approximate solutions and is perhaps the least expensive technique.

Still another method often employed in runoff determinations is the unit hydrograph method, developed by Leroy K. Sherman in 1932, and defined

as a runoff hydrograph resulting from a ’’unit" storm. A "unit" storm is defined as a storm having practically constant rainfall intensity for its duration, termed a unit period, and a runoff volume of one inch (Merritt 1968).

Several key assumptions must be made in applying this method, namely: (1) rainfall intensity is constant for its duration; (2) the effective rainfall is uniform over the entire drainage area; (3) the ordinate of the direct runoff hydrographs of a common base time are directly proportional to the total amounts of direct runoff represented by each hydrograph (Chow 1964). The last noted assumption allows for superposition and enables calculation of the runoff for a storm of any intensity and/or duration.

The hydrograph method has wide applicability and gives a more accurate answer in determining runoff than the other methods discussed (Merritt 1968). Whereas the methods employed by others to determine runoff flows and volumes have dealt with basic hydrologic principles and formulas, the resolution of the constituents of the runoff contributing to the pollution of receiving waters lends itself to more varied and diverse techniques.

A sophisticated deterministic model entitled, "The Storm Water Management Model," was developed for the Environmental Protection Agency (Franklin Institute 1970).

The results of numerous other studies (Shigorinl9s6), (Sylvester 1960), (Akerlinch 1950), (Stander 1961), (Wiebel, et al. 1964), indicate wide variations in the concentrations of runoff biochemical oxygen demand, chemical oxygen demand, suspended solids, and nutrients such as nitrogen and phosphorus

Viessman summarized the reported information describing the composition of urban storm drainage and methods of developing water quality models for runoff from urban areas (Viessman 1968).

The pollution concentrations and loads from storm water runoff were evaluated in Tulsa, Oklahoma (Avco 1970). The project included a field assessment of the storm water pollution by sampling of runoff in the metropolitan area. An analytical procedure for correlation of storm water pollution with selectively defined variables was developed. Runoff samples were analyzed in terms of quality standards for various parameters including: biochemical oxygen demand, chemical oxygen demand, chlorides, pH, solids, total coliform, and fecal coliform. Selected environmental conditions, drainage and precipitation data, along with storm water pollution factors, provided input data for functional relationships enabling assessment of pollution from storm water runoff (Avco 1970).

The American Public Works Association Research Foundation reported the causes and remedies of water pollution from surface drainage in 1967.

The environmental pollution factors and potential pollution effects resulting from the water and waste contacts during rainfall and runoff were analyzed based upon collected field data and theoretical calculations. The factors studied included: street refuse and litter, catch basins, chemicals, and solids deposition. The results indicate that street refuse could present a significant pollution load in terms of biochemical oxygen demand (APWA 1967).

Sartor and Boyd found that those materials accumulated on street surfaces contribute substantially to urban pollution from runoff. The similarity between the composition of runoff from streets and municipal wastewater was illustrated. Results based on a hypothetical United States city indicate that the runoff from the first hour of a moderate intensity storm contributes more pollutional load than the municipal wastewater during the same period of time. The runoff quality was reported in terms of biochemical oxygen demand (BOD), chemical oxygen demand (COD), nitrates, phosphates, total and volatile solids, and a range of pesticides and heavy metals (Sartor 1972).

Rainfall pollution generally occurs in three zones: the sky, the ground, and in the drainage system. Pollution of storm water on the ground is paramount in considering urban runoff. Precipitation falling on impervious areas will runoff rather quickly and wash out polluting materials which may have accumulated (APWA 1969).

This accumulation of debris which is found in the streets, along the curbs, and in the gutters can be defined as street refuse or litter. Litter contributes to the overall pollutional loading of the runoff. The sources of street litter vary from community to community, season to season, and area to area of the same community (APWA 1969).

The sources of materials found or street surfaces vary greatly. However, the bulk of those come from pavement, motor vehicles, atmospheric fallout, vegetation, runoff from adjacent land areas, litter, spills, and antiskid compounds (Sartor 1972). Many of these components are difficult to quantify but deserve mention. The report shows that the solids loading of street refuse varies significantly from city to city and from land use to land use. Attempts to relate indirect factors such as traffic speed, traffic density, and parking density to loading proved futile. Other, more dominant factors such as land use, season, and rainfall frequency had greater effects.

The areas of a community can be classified as residential, commercial, and industrial. It is important to note that an area classified as residential or commercial in one section of an urban community is not the same environmentally as another area so classified. For example, in a new middle to upper class subdivision, the general environmental conditions are normally good to excellent. The yards are well kept with no litter or piles of rubble. Furthermore, most residents in these areas keep clean the portion of the street fronting their property. A different section of the same community may have

the same zoning, be classified the same, but may have entirely different environmental conditions (Avco 1970).

Although there is considerable variation amongst land use categories, when taken all together, streets in industrial areas generally tend to be more heavily loaded than residential streets. Commercial streets tend to be more heavily loaded than industrial (Sartor 1972).

Analysis of the results of this study show that some trends are apparent where loading intensities are compared on the basis of land use category (Sartor 1972). Light industry areas tend to be heavily loaded with both BOD and COD and the commercial areas only lightly loaded. Areas such as shopping centers generally receive more frequent street sweeping than industrial areas. This may explain the difference in loading for the two areas. In the industrial areas it was observed that heavy industry was dirtier than light industry (Sartor 1972).

The American Public Works Association report indicated dust and dirt to be the major contributors of the street refuse components. Organics and vegetation could affect biochemical oxygen demand (BOD) values but the amounts of such materials were generally less than the amounts of dust and dirt. Paper, wood, and cloth likewise were quantitatively small, however, the potential "aesthetic pollution" caused by these materials is high (APWA 1969).

The constituents of urban runoff that contribute to pollutional loading have been established (Avco 1970) (Sartor 1972) (FWPCA 1967) (APWA 1969). The technique of determining amounts of runoff have also been recognized. However, a synthesis of these two components is essential to evaluate the problems of evaluating the loading attributable to urban runoff. Sartor utilized a gage network to obtain runoff volumes and then sampled for constituents (Sartor 1972). In the Chicago studies, quantities of runoff were set and investigations into the constituents of the runoff were conducted (APWA 1969). The results of studies done in the Houston area were used to develop a model to predict runoff volumes and quality of the runoff (Espey, Winslow 1967) (Winslow, Espey 1972).

Rainfall and runoff data from eleven urban and six rural watersheds in the Houston area were reduced to thirty minute unit hydrographs (Espey 1967). These data were combined with data observed for twenty-two urban and eleven rural watersheds which had previously been reduced. Multiple linear regression analyses established the equations which describe the thirty minute unit hydrograph for the urban and rural conditions. These equations were compared with previously derived equations to develop the equation of best fit. The equations were expressed in terms of impervious cover, channel vegetation, and secondary drainage facilities resulting from urbanization. These equations were applied to watersheds in Houston, Texas (Espey 1967).

Winslow later applied these equations to a planned community near Houston. The effects of different residential settings, soil types, and

pervious pavement on the quantity and quality of storm runoff were described by modifying these expressions. These models are used to predict the storm runoff hydrograph for a given rainfall and the concentration of thirteen water quality parameters at intervals during the storm (Winslow 1972).

The pollutional load from non-point sources has not been established in sufficient detail. The study of the Houston area represent the only investigation of non-point sources of waste pollution in the Coastal Zone of Texas. However, there exist mathematical models which can be modified and applied to any area in the Coastal Zone.

METHODOLOGY SELECTED

The Corpus Christi, Texas area was chosen by the Coastal Research Management Project as a study area for determining the effects of economic, environmental, and social policies on future development.

Because of the similarities that exist between the Houston area and the Corpus Christi area, the methodology of Winslow and Espey was applied to the study area.

A comparison of the two areas shows the similarity of such aspects as climate, topography, geology, and land use.

Climate

The Corpus Christi and Houston areas are in the coastal plain of the Gulf of Mexico. The climate of the Houston area is characterized by short mild winters, long hot summers, and high humidity. The mean annual tempera ture is about 69°F and average annual rainfall is 45 inches (Johnson 1965). The average annual rainfall of the Corpus Christi area is a little over thirty inches over the last three years (Meterological Data 1970-1972). The average temperature varies from 85°F in August to 58°F in January (Soil Survey Series 1960). The seasons are much the same in both areas.

Topography

The two areas are on level coastal plains with low permeable clay soils. The slope of the land in the Corpus Christi area rises gently from sea level near the surf of Corpus Christi Bay to about 150 feet at the northwestern part of Nueces County. The Houston area also has a slight rise in elevation that varies from 35 feet to 135 feet.

Land Use

The effects of the oil refining and petrochemical industries influence the land use. Agriculture conbributes a significant portion of the land use in the two areas. Residential development has dominated both areas in recent years.

The methodology consists of a set of empirically derived equations which predict the unit hydrograph. A rainfall-runoff relationship, and water quality.

Equations predicting the shape of the thirty minute unit hydrograph for Houston area watersheds were developed by Espey and Winslow (1967). Those equations utilized parameters which effectively define the shape of the hydrograph.

The equations presented in Table I were employed in the Corpus Christi area to compute the runoff hydrographs.

in which: Tr = Time of rise, minutes Q = Peak discharge, cfs Tg = Base time, minutes Wsq = Time between points on the hydrograph when the discharge is equal to 1/2Q, minutes Wyg = Time between points on the hydrograph when the discharge is equal to 3/4Q, minutes A = Drainage area, square miles J = Urbanization factor L = Channel length, feet S - Channel slope, foot/foot I = Impervious cover, %

*from Winslow, Espey (1972).

Three parameters are utilized to account for the effect of urbanization, namely the impervious cover (I), the channel improvement factor , and the channel vegetation factor ($2)• The urbanization factor, J, is defined as J = Examples of various urbanization factors are illustrated in Figures 1-4, which show drainage channels in the Corpus Christi area.

A rainfall-runoff relationship was developed to predict the runoff hydrograph for a given storm (Winslow, Espey 1972). The following equation was derived and will be used in the Corpus Christi area:

Run = 0.325 R 1,23 M 0,23 1 0,067 SI" 0,12

( 7 )

in which: Run = Total runoff, inches R = Total rainfall, inches M = Soil moisture index I = Percentage of impervious cover SI = Soil index

The data used to develop this relationship were obtained from a report by Johnson and Sayre (1973). The other parameters of the equation were derived from various techniques. The soil index (SI), is the maximum permeability of the soil in inches per hour. The soil moisture index (M), is calculated by a procedure similar to that developed by Linsley, et al. (1958).

*from Winslow, Espey (1972).

The unit hydrograph equations and the rainfall-runoff equation (7) were combined and a computer program which predicts the storm runoff hydrograph for a given drainage basin was written. The necessary inputs include the parameters which describe the basic physiographic characteristics of the area and the rainfall in inches for each thirty minute increment of the storm.

The excess rainfall for each thirty minute increment is calculated and applied to the thirty minute unit hydrograph and the resulting runoff hydrographs for each of the thirty minute increments are integrated to yield the total storm runoff hydrograph (Winslow, Espey 1972). The average flow was integrated over the time of the runoff hydrograph to give the volume of the runoff. This method was checked by calculating the product of inches of rainfall and the drainage area.

The water quality model yields the concentration of selected constituents at specific times during a given storm and the total load input to the system for each constituent for the entire storm.

Thirteen water quality equations for different constituents were developed to describe the pollutional effect of the runoff. The constituents and the units in which the results are displayed appear in Table 111. Total insecticides include chlorinated hydrocarbons and phosphorothiates.

*from Winslow, Espey (1972).

Total herbicides include chlorinated hydrocarbons such as 2, 4-D, silvex, and 2,4, 5-T (Winslow, Espey 1972). The equations used in the program to calculate the water quality of storm runoff are presented in Table IV. The derivations of these equations were reported by Winslow and Espey (1972).

Anomalies of the equations include the prediction of a decrease in several of the constituents as the flow increases. This reduction in concentration occurs when the source of the constituent is limited and the increased flow dilutes the concentration. However, on a loading basis, the load increases as flow increases.

The different degrees of urbanization were included in factors which were developed and applied to the equation. The unit hydrograph, rainfall-runoff, and water quality models were combined and expressed in a computer program. This procedure allowed easy use of the method for computing quantities and water quality of runoff from urbanized areas.

DESCRIPTION OF STUDY AREA

Corpus Christi is a city of 204,525 people located on the coastal bend of the Texas coast (Texas Almanac 1969). A physiographic description of the Corpus Christi Nueces County area shows the characteristics which would affect the quantity and quality of runoff.

The following description is from Soil Conservation Service, "Soil Survey Series," 1960, Number 26:

Nueces County is one of several counties that form an almost uniform curve on the western coast of the Gulf of Mexico. This curve is known locally as the Coastal Bend of Texas. Nueces County is in the center of this curve. Its mainland is part of a nearly level coastal plain that is about 40 miles wide and is made up mainly of heavy, blackland soils. The Nueces River flows along the northern boundary of the county and empties into Nueces Bay, which opens into Corpus Christi Bay. Both of these bays lie within the boundaries of the county. In the offshore waters of the county are about five miles of Padre Island and all of Mustang Island. These islands are strips of sand called barrier islands or beaches. They lie about four miles from the southeastern shores of the mainland and extend across the mouth of Corpus Christi Bay. The lagoon between Padre Island and the mainland is less than five feet deep. Boat channels have been dug in the offshore waters. These channels are 12 feet deep or more, but Corpus Christi Channel, which crosses the bay, is 36 feet deep. The offshore islands and tidal lands make up less than ten percent of the land area of the county. About three-fourths of the land area consists of a nearly level, farily smooth coastal terrace that, on the average, falls about three feet in a mile. Only about 17 percent of the county drains northward into the Nueces River and Nueces Bay. Drainage is mainly to the southeast through the shallow, narrow channels of Aqua Dulce, Pintas, and Petronila Creeks. These creeks cross Kleberg County and empty into Baffin Bay. Oso Creek drains

the northeastern quarter of the county and enters Corpus Christi Bay at a point southeast of Corpus Christi. Although the county is on the Gulf of Mexico, the climate is intermediate between that of the humid, subtropical coastal area to the northeast and that of the semiarid area to the west and southwest. The average rainfall ranges from about 25 inches to 28 inches per year. The average monthly temperature in Nueces County are farily high throughout the year. Severe tropical storms occur about once in every ten years, and less severe storms occur about once in five years. When storms strike the coast 100 miles to the east or south, Nueces County received beneficial rains and there is little wind. Hurricanes strike chiefly in August and September, though tropical storms have occurred as early as June and as late as October.

The urban area of Nueces County was considered in this study. The boundaries of the study area are shown in Figures 5, sa, sb, and sc. FIGURE sb. Corpus Christi, Texas

The total area of the study included 136.98 square miles divided into 14 subareas. Physiographic parameters to describe the degree of urbanization of the subareas were employed in conjunction with requirements of the model. The amount of impervious cover was ascertained from discussions with S. L. Johnson of the United States Geological Survey, Mr. Tom Martin of the City of Corpus Cristi, visual observations and photographs as well as information obtained in the literature review. The physiographic characteristics of the subareas are presented in Table V. Subareas 1-13 drain into Corpus Christi Bay while subarea 14 drains into Oso Creek. Subarea 14 represents the entire drainage area for the United States Geological Survey gaging station on Oso Creek. The subareas were derived from the layout of the storm drainage map of Corpus Christi which depicted the main avenues of storm water drainage. The values for channel length (L), channel slope (S), and the size of the subareas were obtained from the United States Geological Survey Maps.

TABLE V SUBAREA PARAMETERS

TRIAL AREA AND CORRELATION

Field data were obtained from the United States Geological Survey and United States Weather Bureau. A gaging station was established on Oso Creek in September 1972. The station is a continuous flow monitoring and periodic quality monitoring site. Included at the site is a rain gage that measures the rainfall on the gage. The gage is located on Oso Creek at the bridge of Farm to Market Road 763, 1.6 miles downstream from the junction of West Oso Creek and Oso Creek. The geographic location of the gate station number 08211520 is latitude 27° 42’ 40", longitude 97° 30’ 6".

Data obtained included flow and precipitation measurements on a daily basis from September 8, 1972 to December 13, 1972. Hourly data also were obtained for several days in September when significant storms occurred. In addition daily and hourly rainfall data were obtained from the United States Weather Bureau station at Corpus Christi International Airport for the period under investigation.

With actual data available to check the results of the model, the model was then applied to the Oso Creek area or subarea 14. Some limiting factors which must be considered before application of the model include the following: (1) the physiographic characteristics of the watershed should be within the range of the characteristics used to derive the equations;

(2) the urban development should be fairly uniformly distributed over the watershed; (3) the unit hydrograph resulting from application of the equation is assumed to have resulted from a uniform rainfall. Under conditions of non-uniform rainfall, the unit hydrograph may change markedly; (4) in predicting future changes in the unit hydrograph, the storage capacity of the secondary drainage system must be considered. If the storage capacity is inadequate, the changes due to urbanization may be less than actually predicted by the equations.

An assumption of uniform rainfall is necessary since only two rain gaging stations exist in the area. The physiographic characteristics fall within the range used in the derivation of the equations. For the test area, urban development is scarce and assumed to be uniform.

Results of the application of the model to the Oso Creek area establish the fact that the model yields a good approximation of the actual flow and volume for that area.

Figure 6 is the actual hydrograph for the Oso Creek basin under study The normal base flow is approximately 2.0 cubic feet per second and the peak discharge shown for the 2.10 inch rainfall was 522.0 cubic feet per second which represents a runoff of 520 cubic feet per second in excess of the base flow. This peak occurred at about 0800 hours on the morning of September 24, 1972. The data from the gage station in the Oso Creek basin indicate that the actual average flow over the duration of the runoff was about 300 cubic feet per second and the volume created from the storm was 580 million gallons (MG) (USGS 1972).

The model was modified to fit the characteristics of the Oso Creek area. The physiographic parameters were assigned values which were calculated and determined to be best suited to the area. As seen in Table V, subarea 14 (on the Oso Creek basin under study) is described by an impervious cover (I) of sas per cent and an urbanization faction (J) of 1.3. These values were assigned after close scrutiny of the area. The values for area (A), slope (S), and channel length (L), were obtained from a United States Geological Survey topographic map. The soil indix (SI), was calculated from data supplied by the Soil Conservation Service, United States Department of Interior, Robstown, Texas. The soil moisture index (M or API), was calculated according to the Linsley technique (Linsley, et al. 1958). A listing of the computer program utilizing the Winslow, Espey equations is found in the Appendix.

Rainfall increments totaling 2.10 inches were inputed to the model over a six hour period since the actual measured rainfall occurred over a six hour period. A summary of the Results of the computations is presented in Table VI.

• Figure 7 shows the predicted runoff hydrograph for the Oso Creek basin. The normal base flow was 2.0 cubic feet per second and the peak flow predicted by the model was 668 cubic feet per second for a net peak runoff of 666 cubic feet per second. The ruhoff volume from the storm predicted by the model was 510 million gallons.

The differences existing between the predicted volumes and flows and the actual volume and flows can be attributed to the physiographic parameters assigned to the subarea. The volume was obtained by multiplying the area of the drainage basin by the runoff in inches or alternatively by multiplying the average flow by the total time of the hydrograph. A comparison of the two sets of data, actual and predicted, show that hydrologically the model predicts the runoff of this rainfall incident.

The model also predicts the water quality of the runoff in terms 13 parameters previously mentioned. However, no actual data was available. The United States Geological Survey measures water quality only periodically and the quality data may or may not be taken after a rainfall. The sampling program is not continuous nor are samples collected regularly. However, water quality data published in the literature lend support to the effectiveness of this model.

The average concentration of some of the parameters obtained by other investigators and the results of the Oso Creek basin are presented in Table VII. Water quality in Oso Creek exhibits similarities to the other areas, especially the Woodlands are where the same model was applied.

Graphical representations of the time history of the concentrations of the pollutants and load of the pollutants for a trial run of the model are illustrated in Figures 8 through 34. The equations predict the concentration of some constituents to decrease as the flow increases. This phenomenon occurs when the source of a given constituent is limited, and the increased flow serves as a dilutent. However, an examination of the load graphs indicates that the load increases as flow increases. These data suggest that as the flow increases the total amount of pollutant passing the sampling point increases although in some cases the concentration decreases.

The graphic results of the model application illustrate some interesting phenomena. For example, the time history of the concentration of total dissolved solids presented in Figure 11 indicates that the total dissolved solids concentration decreases as the flow increases. As the flow decreases after the peak discharge the concentration increases. This phenomenon may be explained by considering a constant release of salt from the soil through discharge of ground water to the stream. During a rainstorm surface run-

off occurs and dilutes the salt content. When the runoff decreases, the discharge of groundwater is the main source of water in the stream and the salt concentration returns to the initial or equilibrium level. The mathematical expression for predicting the total dissolved solids concentration presented in Table IV is such that as the runoff increases the concentration decreases.

The graphic results presented in Figures 13, 19, and 21 depict similar phenomena which may be explained by the nature of the mathematical model developed for each of these constituents. Each of the equations for these quality parameters includes a negative term which increases as the flow increases. Therefore, the concentration of each constituent will decrease until the peak runoff and increase slightly as the runoff subsides. After the runoff from a particular rainfall ends the concentration will increase to some equilibrium concentration.

The history of the chemical oxygen demand (COD) concentration predicted by the application of the model shows a steep increase as the flow increases then a small drop followed by another peak and finally a steady decline as the flow decreases (Figure 23). The initial flush of the soils contains large amounts of organic material which exerts an immediate oxygen demand and accounts for the steep rise in the COD concentration as the flow increases. The equations for predicting COD concentrations change as the ratio of flow to drainage area reaches 5.6 cfs/sq mile. The fluctuations in the time history of the COD concentration are a result of the application of the different equations as the flow to drainage area ratio reaches 5.6 cfs/ sq mile.

A comparison of the peak concentrations of some of the quality parameters predicted by application of the model with the average concentration of those constituents found in municipal wastewater is presented in Table VIII The strength of the runoff is significantly less than that from municipal wastewater.

MODEL APPLICATION

The model was applied to the remainder of the subareas. Since the 2.10 inch rainfall used to check the applicability of the model to this area represents a storm which would occur once in every fifty rainfall occurrences, a more realsitic value to input for rainfall was chosen. Any amount of rainfall can be used as input provided the rainfall event is coded into thirty minute increments. Analysis of available precipitation data published by the United States Meterological Service for the period of January 1970 to December 1972 indicates that the average daily rainfall is 0.48 inches. Days of no measurable precipitation are not included in determining this average (U.S. Meterological Service 1972). Therefore, a rainfall of 0.48 inches over a six hour duration was used to calculate the loadings presented in Table IX. Each of the 14 subareas is characterized by different urbanization factors, impervious cover percentages, soil moisture indices, soil indices, area, and channel length and slope.

The total loads for the 14 subareas for a 2.10 inch rainfall are presented in Table X. A 2.10 inch rainfall occurs once in every 50 rainfall occurences and may be used as the ’’maximum" storm. The runoffs resulting from the two rainfall events are listed in Table XI for each of the subareas.

DISCUSSION OF RESULTS

The application of the model to the Corpus Christi area generates the pollutional load of urban runoff. This load is presented in terms of an oxygen demand, excess nutrients, silt, bacteria, and aesthetics. These pollutants are derived from several sources. The source of nutrients, usually nitrogen and phosphorus, are fertilizers, mineral leaching, and the decomposition of organic material. The oxygen demand is commonly expressed as biochemical oxygen demand (BOD), chemical oxygen demand (COD), and total organic carbon (TOC). The sources of this ’’organic pollution” include degradation of vegetation, organic matter, oil and grease, animal excretions, and human waste products. Human waste products and animal excretions also introduce bacteria measured in terms of total coliform, fecal coliform, and fecal streptococcus. Silt presents a problem to some aquatic life. Large amounts of solids from erosion of the land are found in the runoff and settle out in the receiving waters. The total dissolved solids are generated during erosion of cleared land by the runoff, leaching from minerals, and soluble dust and dirt from streets. Suspended solids, clay silica particles and organic matter may be derived from erosion of cleared land, while dust and dirt are flushed from streets, and unimproved drainage channels (Avco 1970).

Most of the elements contributing to the pollutional load accumulate in the gutters and streets. The city of Corpus Christi uses a brush type street sweeper that sweeps the curb and gutter areas of the streets. The frequency of sweeping is generally once a month on most streets and once a week on the main thoroughfares.

Effective use of street sweeping equipment and frequent flushing of catch basins tend to reduce the shock effect of urban runoff (Sartor 1972) (Avco 1970).

A comparison of the loading expressed in terms of pounds per day attributed to untreated and treated municipal wastewater in Corpus Christi with the runoff loadings predicted by the model provides an indication of the significance of the runoff to the water quality. In developing this comparison only one rainfall event was assumed to occur in a twentyfour hour period; therefore, the loadings can be based on a daily basis. Those comparative results are presented in Tables XII and XIII. The data in Table XII indicate that the strength of the urban runoff is less than that reported for untreated municipal wastewater; however, the data listed in Table XIII indicate that the strength of the urban runoff is similar to the strength of the treated effluents. Therefore, the significance of the urban runoff and the impact on quality of the waters of Corpus Christi Bay is obvious.

CONCLUSIONS

Some conclusions which can be drawn from this study include: (1) The model developed by Winslow and Espey (1972) is applicable to the Corpus Christi area for predicting runoff quality and quantity changes. (2) The estimated pollution load resulting from an "average" rainfall of 0.48 inches is 1184 Ib/day of 155 Ib/day of 132 Ib/day of NH 3 , and 69419 Ib/day TDS. (3) The strength of the urban runoff is less than that reported for untreated municipal wastewater; however, the quality of urban runoff is similar to the quality of biologically treated municipal wastewaters. (4) Volumes of runoff varied with amounts of impervious cover, degree of urbanization, soil moisture, and the topographic features of the area.
