Computer simulation of mass transport in groundwater : affect of macroscopic heterogeneities in hydraulic conductivity
In this study a computer model was used to simulate dissolved chloride movement through alluvial sediments which border the Canadian River in Hutchinson County, Texas. Hydraulic conductivity values of the sediments were ...
Microstructures and sense of shear in the Brevard Zone, southern Appalachians
The Brevard Zone, which separates the Blue Ridge and Inner Piedmont geologic provinces in the southern Appalachians, is a major structural feature with a multiple deformation history. Microstructures in oriented thin ...
Fluid content effect on acoustic impedance and limits of direct detection capability : illustrated on an offshore prospect
The presence of gas and oil in some sand formations decreases the seismic velocity and density to such an extent that anomalously large reflections coefficients are encountered at fluid contacts. Geerstma and Gassmann's ...
Hydrogeologic controls on underflow in alluvial valleys : implications for Texas water law
Groundwater flow in alluvial valleys consists of two components, baseflow and underflow. The baseflow component of the Darcy flux flows normal to the river and contributes to the surface flow. The underflow component moves ...
Hydrogeology of the Hickory Sandstone Aquifer, Upper Cambrian, Riley Formation, Mason and McCulloch Counties, Texas
The Hickory Aquifer is a primary ground water source for Mason, McCulloch, Concho and San Saba counties, Texas. Significant water level declines have been recorded in the Hickory outcrop where large volumes of water are ...
