Approximate areas of recharge to the Chicot and Evangeline aquifer systems in the Houston-Galveston area, Texas Approximate areas of recharge to the Chicot and Evangeline aquifer systems in the Houston-Galveston area, Texas

The purpose of this report is to show the general geographic areas of recharge to the Chicot and Evangeline aquifers in the Houston area, Texas (fig. 1). The areas of recharge shown on the map were determined by interpretations of subsurface hydrology, soil surveys of Harris County, and surface and subsurface geology.

Ground-water resources along the Blue Ridge Parkway, North Carolina Ground-water resources along the Blue Ridge Parkway, North Carolina

The best areas to develop ground water along the Blue Ridge Parkway in North Carolina are in broad draws and in stream valleys where draws open to the valleys. Saprolite thickness in these places can exceed 50 feet and provide adequate ground-water storage; draws are topographic expressions of fracture zones in the underlying bedrock, which transmit water from the overlying saprolite to...

Technique for estimating magnitude and frequency of floods in Illinois Technique for estimating magnitude and frequency of floods in Illinois

A technique is presented for estimating flood magnitudes at recurrence intervals ranging from 2 to 500 years, for unregulated rural streams in Illinois, with drainage areas ranging from 0.02 to 10,000 square miles. Multiple regression analyses, using streamflow data from 241 sampling sites, were used to define the flood-frequency relationships. The independent variables drainage area...

Development of ground water in the Houston District, Texas, 1970-74 Development of ground water in the Houston District, Texas, 1970-74

Total withdrawals of ground water in the Houston district, Texas , increased 9 percent from about 488 million gallons per day in 1970 to about 532 million gallons per day in 1974. The average annual rate of increase from 1960 to 1969 was about 6.3 percent. During 1970-74, increases in pumpage occurred in the Houston, Katy, and NASA areas; decreases occurred in the Pasadena and Alta Loma...
