Ground-water models for water resources planning
John E. Moore
1980, Open-File Report 80-581
In the past decade hydrologists have emphasized the development of computer-based mathematical models to aid in the understanding of flow, the transport of solutes, transport of heat, and deformation in the groundwater system. These models have been used to provide information and predictions for water managers. Too frequently, groundwater was...
Potential for using the Upper Coachella Valley ground-water basin, California, for storage of artificially recharged water
Michael J. Mallory, Lindsay A. Swain, Stephen J. Tyley
1980, Open-File Report 80-599
This report presents a preliminary evaluation of the geohydrologic factors affecting storage of water by artificial recharge in the upper Coachella Valley, Calif. The ground-water basin of the upper Coachella Valley seems to be geologically suitable for large-scale artificial recharge. A minimum of 900 ,000 acre-feet of water could probably...
Microorganisms in stormwater; a summary of recent investigations
Gail E. Mallard
1980, Open-File Report 80-1198
All storm runoff contains a variety of bacteria, including total coliform, fecal coliform, and fecal streptococci, which are derived from the land over which the water flows. Most total coliform are native soil organisms, whereas the fecal coliform and fecal streptococci originate from the feces of wild and domestic animals....
Cost effective stream-gaging strategies for the Lower Colorado River basin; the Blythe field office operations
Marshall E. Moss, Edward J. Gilroy
1980, Open-File Report 80-1048
This report describes the theoretical developments and illustrates the applications of techniques that recently have been assembled to analyze the cost-effectiveness of federally funded stream-gaging activities in support of the Colorado River compact and subsequent adjudications. The cost effectiveness of 19 stream gages in terms of minimizing the sum of...
Outer continental shelf oil and gas activities in the Pacific (Southern California) and their onshore impacts: a summary report, May 1980
George S. Macpherson, Janis Bernstein
1980, Open-File Report 80-645
Outer Continental Shelf (OCS) oil and gas exploration and development have been under way in the Pacific (Southern California) Region since 1966. During that time, there have been four Federal lease sales: in 1966, 1968, 1975 (Sale 35), and 1979 (Sale 48). Oil and gas production from three leases has...
Lemhi Pass drilling project, Montana
Mortimer Hay Staatz
1980, Open-File Report 80-312
The Lemhi Pass district has the largest thorium resources of any vein district in the United States (Staatz and others, 1979, p. 10). Most of the resources occur in veins that have an average grade of between 0.1 and 2.0 percent Th02. More than 200 thorium-bearing veins have been mapped...
Potentiometric map of the Lower Wilcox Aquifer in Mississippi, fall 1979
B. E. Wasson
1980, Open-File Report 80-597
The potentiometric map of the lower Wilcox aquifer is one of a series of maps, prepared by the U.S. Geological Survey in cooperation with the Mississippi Department of Natural Resources , delineating the potentiometric surfaces of the major aquifers in Mississippi. In the outcrop area of the lower Wilcox aquifer...
Graded storm sand layers offshore from the Yukon Delta, Alaska
C. Hans Nelson
1980, Open-File Report 80-712
The northern Bering Sea has a history of severe storm surges. The most recent, and perhaps the worst in historical times, occurred in November, 1974 (Fathauer, 1975). Evidence of storm surge events is exhibited in sea-floor stratigraphy as well as shoreline flooding and indicates that significant widespread changes in sea-floor...
