Item Drainage Areas of Texas Streams Colorado River Basin(U.S. Geological Survey, 1981) Tovar, F. H.; Maldonado, B. N.Item Flood Stages and Discharges For Small Streams in Texas: Compilation of Data through September 1970(U.S. Geological Survey, 1972) Schroeder, E.E.Research Study No. 4-5-65-85, "Hydrologic Investigation of Small Drainage Areas in Texas," is a cooperative program between the Texas Highway Department and the Water Resources Division of the U.S. Geological Survey. This program, which began in September 1964, is financed by funds made available for research by the Texas Highway Department and the U.S. Department of Transportation, Federal Highway Administration. This report is the sixth in a series of interim reports that describe the objectives, planning, instrumentation, progress, and status of the project. The report includes data collected during the 1970 water year. The objective of the program is to obtain basic hydrologic data that may be used to define the magnitude and frequency of floods for drainage areas of less than 20 square miles. When sufficient data have been obtained, a magnitude and frequency analysis of floods for streams of less than 20 square miles will be prepared. These data will supplement those used by Patterson (1963). To accomplish the objective, a network of 151 crest-stage partial-record gages was established. These gages are distributed throughout the State to sample all hydrologic areas and flood-frequency regions as defined by Patterson (1963} and to obtain a representative sample of physical characteristics. Information for unusual peak discharges at ungaged sites is obtained as the opportunity arises. The planning of this program is directed toward providing a useful regional flood-frequency relation for small streams as soon as the necessary data are collected. Recognizing that an annual-flood series distribution will be used, rainfall-runoff simulation techniques are being tested for possible use in extending records of annual peaks. These techniques should afford useable relations sooner than would be possible by using routine techniques such as the "index-flood method."Item Flood Stages and Discharges For Small Streams in Texas: Compilation of Data through September 1971(U.S. Geological Survey, 1973) Schroeder, E.E.Research Study No. 4-5-65-85, "Hydrologic Investigation of Small Drainage Areas in Texas," is a cooperative program between the Texas Highway Department and the U.S. Geological Survey.

This program, which began in September 1964, is financed by funds made available for research by the Texas Highway Department and the U.S. Department of Transportation, Federal Highway Administration. This report is the fourth in a series of interim reports that describe the objectives, planning of the project, the instrumentation, the progress and status of the project, and the data collected during the year. The objective of the program is to obtain basic hydrologic data that may be used to define the magnitude and frequency of floods for drainage areas of less than 20 square miles. When sufficient data have been obtained, a magnitude and frequency analysis of floods for streams of less than 20 square miles will be prepared.

These gages are distributed throughout the State to sample all hydrologic areas and flood-frequency regions as defined by Patterson (1963), and to obtain a representative sample of all physical characteristics. Information for peak discharges at miscellaneous sites is obtained as the need arises. The present flood-frequency analysis (index-flood method) requires a minimum of 10 years of annual peak-discharge data to satisfy the requirements of statistical methods. About 10 years of peak-discharge data are required to sample the variations associated with a minor climatic cycle.Item Run-off and Mean Flow of Some Texas Streams(University of Texas at Austin, 1915-11-20) Taylor, T.U.Item Run-off and mean flow of some Texas streams(University of Texas at Austin, 1915-11-20) Taylor, T.U.Item Run-off and Mean Flow of Some Texas Streams(The University of Austin at Austin, Texas, 1915-11-20) Taylor, T.
