Hydrology of area 4, Eastern Coal Province, Pennsylvania, Ohio, and West Virginia
Donald K. Roth, Morris J. Engelke Jr., and others
1981, Open-File Report 81-343
Area 4 (one of the 24 hydrologic areas defining the Eastern Coal Province) is located at the northern end of the Eastern Coal Province in eastern Ohio, northern West Virginia, and western Pennsylvania. It is part of the upper Ohio River basin, which includes the Beaver, Mahoning, and Shenango Rivers....
Hydrology of area 32, Eastern Region, Interior Coal Province, Indiana
David J. Wangsness, R. L. Miller, Z. C. Bailey, Charles G. Crawford
1981, Open-File Report 81-498
Hydrologic and water-quality information from the coal region in parts of 11 counties in southwestern Indiana are summarized. Pennsylvanian and Mississippian bedrock are overlain by drift and till from the Kansan, Illinoian, and Wisconsinan glaciers that covered two-thirds of the area. Most of the coal is mined from Pennsylvanian coal...
Hydrology of area 14, Eastern Coal Province, Kentucky
F. Quinones
1981, Open-File Report 81-137
The general hydrology of Area 14, Eastern Coal Province, in Kentucky, is described. The area includes 4,423 square miles in the Kentucky, Licking, and Red River basins. Coal-bearing rocks of Pennsylvanian age underlie most of the area. Coal production in 1978 was about 38 million tons, 65% of which was...
Chemical quality of ground water in San Joaquin and part of Contra Costa Counties, California
Stephen K. Sorenson
1981, Water-Resources Investigations Report 81-26
Chemical water-quality conditions were investigated in San Joaquin and part of Contra Costa Counties by canvassing available wells and sampling water from 324 representative wells. Chemical water types varied, with 73 percent of the wells sampled containing either calcium-magnesium bicarbonate, or calcium-sodium bicarbonate type water. Substantial areas contain ground water...
Water type and suitability of Oklahoma surface waters for public supply and irrigation; Part I, Arkansas river mainstem and Verdigris, Neosho, and Illinois river basins through 1978
Jerry D. Stoner
1981, Water-Resources Investigations Report 81-33
Water-quality data in the Arkansas River mainstem and the Verdigris, Neosho, and Illnois River basins are examined for water type and suitability for public water supply and for irrigation use. The classification of water type is based on the relation of the major ions -- calcium, magnesium, sodium, bicarbonate/carbonate, sulfate,...
Gold placer and Quaternary stratigraphy of the Jabal Mokhyat area, southern Najd Province, Kingdom of Saudi Arabia
D. L. Schmidt, W.P. Puffett, W. L. Campbell, Z. H. Al-Koulak
1981, Open-File Report 82-414
An ancient gold placer at Jabal Mokhyat (lat 20?12.2'N., long 43?28'E.), about 90 km east of Qalat Bishah in the southern Najd Province, Kingdom of Saudi Arabia, was studied in 1973. Seven hundred and twenty-eight samples in 25 measured sections were collected along trenches and pits 2.5 m in depth...
Water type and suitability of Oklahoma surface waters for public supply and irrigation; Part 2: Salt Fork Arkansas and Cimarron River basins through 1978
Jerry D. Stoner
1981, Water-Resources Investigations Report 81-39
Water-quality data in the Salt Fork Arkansas and Cimarron River basins within Oklahoma, through 1978, were examined for water type and suitability for public water supply and irrigation use. Of 76 stations with available data, 32 stations or 42 percent were considered to have sufficient data for analysis. The classification...
Simulated hydrologic effects of possible ground-water and surface-water management alternatives in and near the Platte River, south-central Nebraska
Alan W. Burns
1981, Open-File Report 81-1116
Digital computer models were developed and used to simulate the hydrologic effects of hypothetical water-management alternatives on the wetland habitat area near Grand Island, Nebr. Areally distributed recharge to and discharge from the aquifer system adjacent to the Platte River between Overton and Grand Island were computed for four hypothetical...
