Geological Survey research 1972
Water Resources Division, U.S. Geological Survey
1972, Professional Paper 800-D
This collection of 30 short papers is the third published chapter of "Geological Survey Research 1972." The papers report on scientific and economic results of current work by members of the Geologic and Water Resources Divisions of the U.S. Geological Survey.Chapter A, to be published later in the year, will...
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...
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...
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...
Reconnaissance geology of the Precambrian rocks in the Ayn Qunay quadrangle, Kingdom of Saudi Arabia
William C. Overstreet, Jesse William Whitlow, Abdullah O. Ankary
1972, Open-File Report 72-281
The Aya Qunay quadrangle covers an area of 2833 sq km in central Saudi Arabia, Only the western edge of the quadrangle is underlain by Precambrian rocks, which were the subject of this investigation. Toward the east the Precambrian rocks are unconformably overlain by Permian and younger sedimentary rocks. The...
Radiochemical analyses of surface water from U.S. Geological Survey hydrologic bench-mark stations
V.J. Janzer, L.G. Saindon
1972, Open-File Report 72-191
The U.S. Geological Survey's program for collecting and analyzing surface-water samples for radiochemical constituents at hydrologic bench-mark stations is described. Analytical methods used during the study are described briefly and data obtained from 55 of the network stations in the United States during the period from 1967 to 1971 are...
