Surface-water and water-quality data from selected streams and treated waters in the Greensboro Area, North Carolina, 1986-87
M.S. Davenport
1988, Open-File Report 88-169
Water and bottom-sediment samples were collected from April 1986 to September 1987 at 19 sites in Guilford County and the City of Greensboro, North Carolina. Sampling locations included 13 stream sites, two lakes that supply City of Greensboro drinking water, two City of Greensboro finished drinking-water filtration plants, and two...
Bathymetry of Lakes Marion and Moultrie, South Carolina, 1984-85
Glenn G. Patterson, S.W. Logan
1988, Water-Resources Investigations Report 88-4062
Lakes Marion and Moultrie are two large, interconnected reservoirs in the Coastal Plain of South Carolina. Bathymetric surveys during 1984-85 determined that, for the full-pool water surface elevation of 76.8 ft, the volume of Lake Marion is 1,425 ,000 acre-ft, and for the full-pool water surface elevation of 75.0 ft,...
Mineral resources and resource potential map of the Pyramid Peak Roadless Area, Riverside County, California
J.P. Calzia
1988, Miscellaneous Field Studies Map 1999
The Pyramid Peak Roadless Area is underlain by mid-Cretaceous plutonic rocks (granite, granodiorite, and tonalite) that intrude metasedimentary rocks of the Desert Divide Group. The granodiorite grades eastward into strongly deformed mylonitic rocks mapped as part of the Santa Rosa mylonite zone. Metasedimentary rocks, orthogneiss, and anatexites of the Palm...
Effects of fluctuating river-pool stages on ground-water levels in the adjacent alluvial aquifer in the lower Arkansas River, Arkansas
D.A. Freiwald, G.D. Grosz
1988, Water-Resources Investigations Report 87-4279
The U.S. Geological Survey conducted a study in cooperation with the U.S. Army Corps of Engineers to determine the effect of fluctuating the lower Arkansas River. A network of 41 wells was used to delineate 4 cross sections adjacent to river pools 2 and 5 of the McClellan-Kerr Arkansas River...
Map and tabulation of quaternary mass movements along the United States-Canadian Atlantic continental slope from 32 degrees 00 minutes to 47 degrees 00 minutes N. latitude
J.S. Booth, Dennis W. O’Leary, Peter Popenoe, James M. Robb, B.A. McGregor
1988, Miscellaneous Field Studies Map 2027
Since the initial report on the Grand Banks Slump off southern Newfoundland (Heezen and Ewing, 1952), a large body of data on submarine mass movement along the Atlantic continental margin of the United States and Canada has been published.  These data were compiled to provide this distribution map (sheet 1)...
Application of seismic-refraction techniques to hydrologic studies
F.P. Haeni
1988, Techniques of Water-Resources Investigations 02-D2
During the past 30 years, seismic-refraction methods have been used extensively in petroleum, mineral, and engineering investigations and to some extent for hydrologic applications. Recent advances in equipment, sound sources, and computer interpretation techniques make seismic refraction a highly effective and economical means of obtaining subsurface data in hydrologic...
A finite-element model for simulating hydraulic interchange of surface and ground water
K. C. Glover
1988, Water-Resources Investigations Report 86-4319
A model was developed to be useful for predicting changes in streamflow as a result of groundwater pumping. The stream aquifer model is especially useful for simulating streams that flow intermittently owing to leakage to the aquifer or diversion for irrigation or streams that become perched owing to declining hydraulic...
A modular three-dimensional finite-difference ground-water flow model
Michael G. McDonald, Arlen W. Harbaugh
1988, Techniques of Water-Resources Investigations 06-A1
This report presents a finite-difference model and its associated modular computer program. The model simulates flow in three dimensions. The report includes detailed explanations of physical and mathematical concepts on which the model is based and an explanation of how those concepts are incorporated in the modular structure of the...
Activities of the Water Resources Division, California District, in the 1987 fiscal year
C.A. Griner, P.W. Anttila
1988, Open-File Report 88-177
The mission of the Water Resources Division is to provide the hydrologic information and understanding needed for the optimum utilization and management of the Nation 's water resources for the overall benefit of the people of the United States. Several of the most relevant and visible studies being conducted by...
