Hydrologic data for Little Elm Creek, Trinity River Basin, Texas, 1974 Hydrologic data for Little Elm Creek, Trinity River Basin, Texas, 1974

The U.S. Soil Conservation Service is actively engaged in the implementation of flood- and soil-erosion reducing measures in Texas under the authority of "The Flood Control Act of 1936 and 1944" and "Watershed Protection and Flood Prevention Act" (Public Law 566), as amended. The Soil Conservation Service has found that approximately 3,500 floodwater-retarding structures would be...

Progress report on geology of the Edwards aquifer, San Antonio area, Texas, and preliminary interpretation of borehole geophysical and laboratory data on carbonate rocks Progress report on geology of the Edwards aquifer, San Antonio area, Texas, and preliminary interpretation of borehole geophysical and laboratory data on carbonate rocks

This report describes the geology and porosity of the rocks of the Edwards aquifer, with particular attention to the eastern half of the San Antonio area. The data were obtained from geologic and geophysical studies of nine cored test holes, from laboratory analyses of samples of the aquifer materials, and from recent stratigraphic studies by other investigators. The Georgetown Formation...

Test drilling for ground water in Hudspeth, Culberson, and Presidio Counties in westernmost Texas Test drilling for ground water in Hudspeth, Culberson, and Presidio Counties in westernmost Texas

From November 1973 to October 1974, the U.S. Geological Survey drilled four deep test holes to supplement hydrologic and geophysical studies evaluating fresh ground water in the basins of westernmost Texas. For each test, samples of drill cuttings were collect·ed, borehole geophysical logs were run, and water samples were collected from specific zones. The Leopold Guerra No. 1 test hole...

Sediment characteristics of streams in the eastern Piedmont and western Coastal Plain regions of North Carolina Sediment characteristics of streams in the eastern Piedmont and western Coastal Plain regions of North Carolina

The sediment-transport characteristics of streams were determined in a 15,500-square-kilometre (6,000-square-mile) area of the Coastal Plain and Piedmont regions of eastern North Carolina during 1969-73. The study covered all or parts of 21 counties and included data for 28 sediment-sampling stations in parts of 4 major river basins?the Roanoke, Pamlico, Neuse, and Cape Fear. Annual...

Hydrologic interpretation of geophysical data from the southeastern Hueco Bolson, El Paso, and Hudspeth Counties, Texas Hydrologic interpretation of geophysical data from the southeastern Hueco Bolson, El Paso, and Hudspeth Counties, Texas

Airborne-electromagnetic and earth-resistivity surveys were used to explore for fresh ground water in the Hueco Bolson southeast of El Paso, Texas. Aerial surveys were made along about 500 miles (800 km) of flight line, and 67 resistivity soundings were made along 110 miles (180 km) of profile. The surveys did not indicate the presence of any large bodies of fresh ground water, but...

Time of travel of solutes in the East Fork Trinity River, November 1975; and Elm Fork Trinity River, December 1975; Trinity River basin, Texas Time of travel of solutes in the East Fork Trinity River, November 1975; and Elm Fork Trinity River, December 1975; Trinity River basin, Texas

The U.S. Geological Survey, in cooperation with the North Central Texas Council of Governments, the Trinity River Authority of Texas, and the Texas Water Development Board, conducted two time-of-travel studies in the Trinity River basin in November and December, 1975. Field data were collected on the East Fork Trinity River during November 18-22, 1975, and on the Elm Fork Trinity River...

Heat flow near Charleston, South Carolina Heat flow near Charleston, South Carolina

As part of a study of the geology and geophysics of the Charleston, South Carolina, area, thermal conductivity, thermal gradient, and heat flow were determined in a 742 meter, continuously cored, test hole. The hole is located 41 km west-northwest of Charleston near Clubhouse Corners, Figure 1, directly over a gravity and magnetic high and the possible hypocenter of the 1889 Charleston...
