The United States Geological Survey in Alaska: Accomplishments during 1977
Kathleen M. Johnson, editor(s)
1978, Circular 772-B
United States Geological Survey projects in Alaska study a wide range of topics of economic and scientific interest. Work done in 1977 includes contributions to economic geology, regional geology, stratigraphy, engineering geology, hydrology, and marine geology. Many maps and reports covering various aspects of the geology and mineral and water...
Water resources data for West Virginia, water year 1977
Water Resources Division, U.S. Geological Survey
1978, Water Data Report WV-77-1
Water resources data for the 1977 water year for West Virginia consist of records of stage, discharge, and water quality of streams and springs; stage and contents of lakes and reservoirs; and water levels in wells. This report contains discharge records for 129 gaging stations; stage only records for 2...
Annual summary of ground-water conditions in Arizona, spring 1977 to spring 1978
Water Resources Division, U.S. Geological Survey
1978, Water-Resources Investigations Report 78-144
The withdrawal of ground water was about 5.5 million acre-feet in Arizona in 1977. About 4.7 million acre-feet of ground water was used for the irrigation of crops in 1977. The Salt River Valley and the lower Santa Cruz basin are the largest agricultural areas in the State. For 1973-77,...
Geological Survey research 1978
Water Resources Division, U.S. Geological Survey
1978, Professional Paper 1100
This U.S. Geological Survey activities report includes a summary of 1978 fiscal year scientific and economic results accompanied by a list of geologic and hydrologic investigations in progress and a report on the status of topographic mapping. The summary of results includes: (1) Mineral and water resources, (2) Engineering geology...
Application of digital profile modeling techniques to ground-water solute transport at Barstow, California
Stanley G. Robson
1978, Water Supply Paper 2050
This study investigated the use of a two-dimensional profile-oriented water-quality model for the simulation of head and water-quality changes through the saturated thickness of an aquifer. The profile model is able to simulate confined or unconfined aquifers with nonhomogeneous anisotropic hydraulic conductivity, nonhomogeneous specific storage and porosity, and nonuniform saturated...
Floods of September 1970 in Arizona, Utah, Colorado, and New Mexico
R.H. Roeske, Maurice E. Cooley, B. N. Aldridge
1978, Water Supply Paper 2052
During September 5-7, 1970, unusually large floods occurred in the mountains of central Arizona and in the Four Corners area of Arizona, Utah, Colorado, and New Mexico. Flooding also occurred in southern and northeastern Arizona. The record-high rainfall of September 5 occurred when a mass of moist tropical air from...
Distribution of dissolved nitrate and fluoride in ground water, Highland-East Highlands, San Bernardino County, California
Lawrence A. Eccles, John M. Klein
1978, Water-Resources Investigations Report 78-14
In the Highland-East Highlands area of southern California, concentrations of nitrate in water from many wells exceed the U.S. Environmental Protection Agency 's and the California Department of Health 's recommended limit for public water supplies. The nitrate standards for public water supplies in the study area are commonly met...
Low-flow characteristics of streams in the lower Wisconsin River basin
W.A. Gebert
1978, Water-Resources Investigations Report 77-118
Low-flow characteristics of streams in the lower Wisconsin River basin are presented. Included are estimates of low-flow frequency and flow duration at 11 gaging stations; low-flow frequency characteristics at 26 low-flow partial-record stations and 70 miscellaneous sites; and a list of low-flow discharge measurements at 155 miscellaneous sites where insufficient...
Program for evaluating stream quality in North Carolina
Hugh B. Wilder, Clyde E. Simmons
1978, Circular 764
The design and objectives of the program for evaluating stream quality in North Carolina are described. Using water-quality and streamflow data collected since the 1940's, a study is underway to define certain variations in water quality, to quantify the effects of man 's activities on water quality, and to determine...
A theoretical basis for exploration for native copper in northern Wisconsin
Walter S. White
1978, Circular 769
Exploration for native copper in the Keweenawan lavas of northern Wisconsin has been concentrated in areas of relatively shallow overburden that have sparse to numerous outcrops. Lack of success of this exploration suggests that if large deposits, comparable to those of northern Michigan, are present, they are more likely to...
Subsurface geology and porosity distribution, Madison Limestone and underlying formations, Powder River basin, northeastern Wyoming and southeastern Montana and adjacent areas
James A. Peterson
1978, Open-File Report 78-783
To evaluate the Madison Limestone and associated rocks as potential sources for water supplies in the Powder River Basin and adjacent areas, an understanding of the geologic framework of these units, their lithologic facies patterns, the distribution of porosity zones, and the relation between porosity development and stratigraphic facies is...
Water-quality investigation of the Tyronza River Watershed, Arkansas
T.E. Lamb
1978, Open-File Report 78-175
The results of a 1-year study of surface-water quality in the Tyronza River Watershed are presented to document conditions before implementation of Soil Conservation Service programs. The report includes a general description of the watershed's topography, geology, and aquifers, and the results of monthly measurements of discharge at five sites,...
Stormwater-runoff data for a highway area, Broward County, Florida
Jack Hardee, Robert A. Miller, Harold C. Mattraw Jr.
1978, Open-File Report 78-612
Rainfall, stormwater discharge, and water-quality data for both rainfall and runoff are summarized for a highway area near Pompano Beach, Florida. Loads for 20 water-quality constituents were computed for the runoff from 41 storms between April 1975, and July 1977. The basin of 58.3 acres contains a 3,000 ft segment...
Hydrologic data for North Creek, Trinity River basin, Texas, 1976
C.C. Kidwell
1978, Open-File Report 77-732
The U.S. Soil Conservation Service is actively engaged in the installation of flood- and soil-erosion reducing structures in Texas under the authority of "The Flood Control Act of 1936 and 1944" and Watershed Protection and Flood Prevention Act" (Public Law 566), as amended. The Soil Conservation Service has found that...
