Summary mineral resource appraisal of the Richfield 1° x 2° quadrangle, west-central Utah
Thomas August Steven, Hal T. Morris
1987, Circular 916
The mineral resource potential of the Richfield 1° x 2° quadrangle, Utah, has been appraised using geological, geophysical, geochemical, and remote-sensing techniques. These studies have led to many publications giving basic data and interpretations; of these, a series of 18 maps at 1:250,000 and 1:500,000 scales summarizing aspects of the...
Surface-water hydrology of the Little Black River basin, Missouri and Arkansas, before water-land improvement practices

1987, Water-Resources Investigations Report 87-4076
The U. S. Department of Agriculture, Soil Conservation Service, in accordance with Public Law 566, is implementing various types of water-land improvement practices in the Little Black River basin in southeastern Missouri. These practices are designed, in part, to decrease the suspended sediment (SS) transport in the basin, decrease flood...
Uranium resource assessment by the Geological Survey; methodology and plan to update the national resource base
Warren Irvin Finch, Richard B. McCammon
1987, Circular 994
Based on the Memorandum of Understanding {MOU) of September 20, 1984, between the U.S. Geological Survey of the U.S. Department of Interior and the Energy Information Administration {EIA) of the U.S. Department of Energy {DOE), the U.S. Geological Survey began to make estimates of the undiscovered uranium endowment of selected...
Streamflow characteristics at hydrologic bench-mark stations
C.L. Lawrence
1987, Circular 941
The Hydrologic Bench-Mark Network was established in the 1960's. Its objectives were to document the hydrologic characteristics of representative undeveloped watersheds nationwide and to provide a comparative base for studying the effects of man on the hydrologic environment. The network, which consists of 57 streamflow gaging stations and one lake-stage...

Traveltime and dispersion in the New River, Hinton to Gauley Bridge, West Virginia
David H. Appel, S. B. Moles
1987, Water-Resources Investigations Report 87-4012
Traveltime and dispersion studies were conducted on a 65-mile-long reach of the New River between Hinton and Gauley Bridge, West Virginia. Four sets of measurements were made from August 1985 to May 1986 at river discharges of about 2,220, 3 ,200, 9,200, and 18,000 cu ft/sec, which correspond to flow...
Ground-water resources of Jones County, Mississippi
E. H. Boswell, G.A. Bednar, Daphne Darden
1987, Water-Resources Investigations Report 85-4342
Jones County, Mississippi, is supplied with groundwater from aquifers in strata of Eocene and younger age. The largest groundwater withdrawals are from aquifers in the Catahoula Sandstone of the Miocene aquifer system that occur at depths of 200 and 400 ft in the Laurel area. Several public and industrial water...
Conference on Continental margin mass wasting and Pleistocene sea-level changes, August 13-15, 1980

The principle of superposition and its application in ground-water hydraulics
Thomas E. Reilly, O. Lehn Franke, Gordon D. Bennett
1987, Techniques of Water-Resources Investigations 03-B6
The principle of superposition, a powerful mathematical technique for analyzing certain types of complex problems in many areas of science and technology, has important applications in ground-water hydraulics and modeling of ground-water systems. The principle of superposition states that problem solutions can be added together to obtain composite solutions. This...
