Approximate potentiometric surfaces for the aquifers of the Texas coastal uplands system, 1980
Sergio Garza, B.D. Jones, E.T. Baker
1987, Hydrologic Atlas 704
The National Water Commission recommended that the U.S. Geological Survey conduct intensive studies of the important regional aquifer systems in the United States, particularly those with declining water levels and deteriorating water quality.  The result has been a series of Regional Aquifer-System Analysis (RASA) studies, one of which is the...
Water resources data, South Carolina, water year 1986
C.S. Bennett, R.D. Hayes, K.H. Jones, T.W. Cooney
1987, Water Data Report SC-86-1
Water resources data for the 1986 water year for South Carolina consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels of ground-water wells. This volume contains records for water discharge at 100 gaging stations, stage only...
Reconnaissance of hydrology, land use, ground-water chemistry, and effects of land use on ground-water chemistry in the Albuquerque-Belen basin, New Mexico
S. K. Anderholm
1987, Water-Resources Investigations Report 86-4174
In 1984, the U.S. Geological Survey began regional assessments of groundwater contamination in 14 areas, one of which was the Albuquerque-Belen basin. Groundwater recharge occurs along the basin margins. Groundwater discharge occurs as evapotranspiration in the Rio Grande valley, pumpage, and groundwater flow to the Socorro basin. Open-space land use,...
Late Mississippian gastropods of the Chainman Shale, west-central Utah
Mackenzie Gordon Jr., Ellis L. Yochelson
1987, Professional Paper 1368
The Chainman Shale of Mississippian (Osagean to late Chesterian) age, well exposed in the Confusion Range of western Utah, has yielded a profusion of fossils during investigations conducted by the U.S. Geological Survey in the past 30 years. Conspicuous among these fossils are gastropods, which range in age from latest...
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...
Runoff characteristics and washoff loads from rainfall-simulation experiments on a street surface and a native pasture in the Denver metropolitan area, Colorado
Martha H. Mustard, Sherman R. Ellis, Johnnie W. Gibbs
1987, Professional Paper 1441
Rainfall simulation studies were conducted in conjunction with the Denver Regional Urban Runoff Program to: (1) Compare runoff quantity and quality from two different intensities of rainfall on impervious plots having identical antecedent conditions, (2) document a first flush of constituent loads in runoff from l,000-square-foot street-surface plots, (3) compare...
Conference on Continental margin mass wasting and Pleistocene sea-level changes, August 13-15, 1980
David W. Folger, John C. Hathaway, editor(s)
1987, Circular 961
A conference on Continental Margin Mass Wasting and Pleistocene Sea-Level Changes was held in Woods Hole, Mass., August 13-15, 1980. Forty-seven participants, representing many government, academic, and industrial organizations, discussed the current state of knowledge of the features of marine mass wasting and of the interrelations of factors influencing them....
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
W.R. Berkas, Suzanne R. Femmer, T. O. Mesko, B. W. Thompson
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...
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...
Evaluation of the potential for artificial ground-water recharge in eastern San Joaquin County, California — Phase 3
S. N. Hamlin
1987, Water-Resources Investigations Report 87-4164
Infiltration tests were used to evaluate the potential of basin spreading surface water as a means of artificially recharging the aquifer system in eastern San Joaquin County, California. Two infiltration sites near Lockeford and Linden were selected on the basis of information collected during the first two phases of the...
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...
COGEOMAP; a new era in cooperative geologic mapping
Juergen Reinhardt, David M. Miller
1987, Circular 1003
A program of cooperative geologic mapping was established between the U.S. Geological Survey and the State geological surveys in fiscal year 1985. The main purpose of the program is to increase general-purpose geologic mapping throughout the Nation. By combining State and Federal resources for geologic mapping through this cooperative program,...
