This collection of 37 short papers is the second published chapter of "Geological Survey Research 1972." The papers report on scientific and economic results of current work by members of the Conservation, Geologic, and Water Resources Divisions of the U.S. Geological Survey.Chapter A, to be published later in the year,...
Vegetation of prairie potholes, North Dakota, in relation to quality of water and other environmental factors
R. E. Stewart, H.A. Kantrud
1972, Professional Paper 585-D
Measurements of specific conductance provide an adequate indication of the average salinity of surface waters in natural ponds and lakes of the northern .prairie region. Yearly and seasonal variations in specific conductance were much greater in brackish and subsaline wetlands than in fresh-water areas. The principal vegetational types. Land-use practices...
The hydraulic geometry of some Alaskan streams south of the Yukon River
William W. Emmett
1972, Open-File Report 72-108
Channel geometry surveys were conducted to determine bankfull stage, discharge, and other hydraulic parameters at 22 locations along the proposed route of the trans-Alaska pipeline corridor south of the Yukon River. Combined with the records from gaging stations located at some of the sites, the data are sufficient to describe...
Ground-water hydrology of prairie potholes in North Dakota
C. E. Sloan
1972, Professional Paper 585-C
Prairie potholes (sloughs) are water-holding depressions of glacial origin in the prairies of the Northern United States and southern Canada. Water is supplied to the potholes by precipitation on the water surface, basin runoff, and seepage inflow of ground water. Depleticn of pothole water results from evapotranspiration, overflow, and seepage...
Records of water-level measurements in wells in the Oklahoma panhandle, 1966-70
Donald L. Hart Jr.
1972, Open-File Report 71-344
Investigations of the ground-water resources of the Oklahoma panhandle by the U.S. Geological Survey in cooperation with the Oklahoma Water Resources Board includes collection of water-level records; the systematic collection of these records began in 1937. Records of many shallow wells were compiled in 1937 and periodic measurements were made...
Heavy-minerals reconnaissance in the Fatimah Formation, near Jiddah, Saudi Arabia
Louis Gonzalez
1972, Open-File Report 72-135
Near Jiddah, Saudi Arabia, a heavy-minerals survey was made in the Precambrian sediments o# the Fatima Formation. Samples measuring 0.25 cubic meters were taken in a net related to the drainage system and. washed in a sluice. The concentrates were tested. for 29 elements which included precious and. base metals,...
Hydrologic investigations of prairie potholes in North Dakota, 1959-68
W. S. Eisenlohr Jr., editor(s)
1972, Professional Paper 585-A
A prairie pothole is a depression in the prau1e, capable of storing water, that is the result of glacial processes. Years ago, there were many hundreds of thousands of prairie potholes in the North-Central United States, but large numbers of them have been drained for agricultural use. This report is...
