Water level measurements in 52 shallow boreholes in the San Francisco Bay region
Edward F. Roth
1978, Open-File Report 78-935
Water-level measurements have been read in 52 cased boreholes in the San Francisco bay region. These measurements are compared to water-table depths determined by P-wave velocity. A velocity in excess of 1200 m/s is taken as the depth of the upper surface of the water table. This method works best...
Potential hazards from future eruptions of Mount St. Helens Volcano, Washington
Dwight Raymond Crandell, Donal Ray Mullineaux
1978, Bulletin 1383-C
Mount St. Helens has been more active and more explosive during the last 4,500 years than any other volcano in the conterminous United States. Eruptions of that period repeatedly formed domes, large volumes of pumice, hot pyroclastic flows, and, during the last 2,500 years, lava flows. Some of this activity...
Eolian sand and interbedded organic horizons at Kealok Creek on the Arctic Coastal Plain of Alaska: possible regional implications
L. David Carter, S.W. Robinson
1978, Open-File Report 78-320
Eolian sand has long been recognized as a widespread but minor facies of supposedly dominantly marine sediments of the Gubik Formation of the Arctic Coastal Plain (Smith and Mertie, 1930; Black, 1951 and 1964; O'Sullivan, 1961). Descriptions of eolian landforms of the coastal plain have been published by several authors,...
Evaluation of hydrogeologic aspects of proposed salinity control in Paradox Valley, Colorado
Leonard F. Konikow, M. S. Bedinger
1978, Open-File Report 78-27
The salt load in the Dolores River increases by about 200,000 tons per year where it crosses Paradox Valley, Colorado, because of the discharge of a sodium chloride brine from an underlying aquifer. A ground-water management program to nearly eliminate this major source of salt, which eventually enters the Colorado...
Hydrogeologic considerations for an interstate ground-water compact on the Madison aquifer, northern Great Plains
Leonard F. Konikow
1978, Open-File Report 78-138
The development of an interstate ground-water compact for the Madison aquifer in the Northern Great Plains may provide a framework to allocate equitably this large ground-water resource while avoiding possible future interstate legal conflicts. However, some technical problems will have to be resolved first. A compact designed to regulate or...
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,...
Linear ground-water flow, flood-wave response program for programmable calculators
John Michael Kernodle
1978, Open-File Report 78-356
Two programs are documented which solve a discretized analytical equation derived to determine head changes at a point in a one-dimensional ground-water flow system. The programs, written for programmable calculators, are in widely divergent but commonly encountered languages and serve to illustrate the adaptability of the linear model to use...
Geochemical map showing the distribution and abundance of copper in stream sediments in the Seward and Blying Sound quadrangles, Alaska
R. B. Tripp, W.D. Crim, E.F. Cooley, G.W. Day
1978, Miscellaneous Field Studies Map 880-E
Reconnaissance geochemical and mineralogical sampling was done in the Seward and Blying Sound quadrangles during 1975 and 1976 as part of the Alaska Mineral Resources Assessment Program (AMRAP). This map shows the distribution and abundance of copper in stream-sediment samples. Stream-sediment samples were collected at 569 sites from active stream channels...
The Coffee Sand and Ripley aquifers in Mississippi
E. H. Boswell
1978, Water-Resources Investigations Report 78-114
The Coffee Sand and Ripley aquifers, of Cretaceous age, are in the Selma Group in northern Mississippi. The aquifers contain freshwater in an area of about 4,400 square miles in northern Mississippi. Water produced from the aquifers by public water systems and numerous industries in 1975 averaged about 4 Mgal/d....
