Preliminary assessment of ground-water resources of Lauderdale County, Tennessee
W. S. Parks, J. K. Carmichael, D. D. Graham
1985, Water-Resources Investigations Report 84-4104
The ground-water resource in Lauderdale County is in a rudimentary stage of development. The principal shallow aquifers are the Mississippi alluvial deposits of Quaternary age and the Cockfield Formation, Memphis Sand, and Fort Pillow Sand of Tertiary age. Water levels fluctuate seasonally. High water levels generally occur in the winter,...
Small-area snow surveys on the northern plains of North Dakota
Douglas G. Emerson, T.R. Carroll, Harold Steppuhn
1985, Water-Resources Investigations Report 85-4026
Snow-cover data are needed for many facets of hydrology. The variation in snow cover over small areas is the focus of this study. The feasibility of using aerial surveys to obtain information on the snow water equivalent of the snow cover in order to minimize the necessity of labor intensive...
The flood of December 1982 and the 100- and 500-year flood on the Buffalo River, Arkansas
B.L. Neely
1985, Water-Resources Investigations Report 85-4192
Flood profiles, peak discharges, and stages were determined for the December 1982, the 100-year, and the 500-year floods at 17 sites along the Buffalo River, Arkansas. Typical synthetic stage hydrographs for the 100- and 500-year floods were determined for each site. Flow duration data for gaging stations at St. Joe...
Estimation of selected flow and water-quality characteristics of Alaskan streams
Bruce Parks, R. J. Madison
1985, Water-Resources Investigations Report 84-4247
Although hydrologic data are either sparse or nonexistent for large areas of Alaska, the drainage area, area of lakes, glacier and forest cover, and average precipitation in a hydrologic basin of interest can be measured or estimated from existing maps. Application of multiple linear regression techniques indicates that statistically significant...
Salinity characteristics and distribution and effects of alternative plans for freshwater withdrawal, Little Manatee River estuary and adjacent areas of Tampa Bay, Florida
Mario Fernandez
1985, Water-Resources Investigations Report 84-4301
The Little Manatee River, a coastal stream that empties into Tampa Bay, Florida, may be used as a source of freshwater. Reduction of streamflow will result in upstream movement of saltwater in the stream. Data on streamflow, tide stage, and specific conductance describe the salinity distribution of the estuary. Vertical...
Water-level declines in the Amargosa Valley area, Nye County, Nevada, 1962-84
W. D. Nichols, J. P. Akers
1985, Water-Resources Investigations Report 85-4273
Groundwater flow in the Amargosa Valley area is in Nevada complex and involves a valley fill aquifer and an underlying carbonate rock aquifer. Groundwater development in the area is in the valley fill aquifer, about 10 mi. south-west of Lathrop Wells. Water levels measured in selected wells in the area...
Time of travel, water quality, and bed-material quality in the Cuyahoga River within the Cuyahoga Valley National Recreation area, Ohio
C.J. Childress
1985, Water-Resources Investigations Report 85-4065
Three studies were conducted in the Cuyahoga Valley National Recreation by the U. S. Geological Survey to (1) establish the relationship between time of travel and discharge through the park reach of the Cuyahoga River, (2) characterize water quality of the Cuyahoga River within the park over a 24-hour period,...
Evaluating earthquake hazards in the Los Angeles region— An earth-science perspective
Joseph I. Ziony, editor(s)
1985, Professional Paper 1360
Potentially destructive earthquakes are inevitable in the Los Angeles region of California, but hazards prediction can provide a basis for reducing damage and loss. This volume identifies the principal geologically controlled earthquake hazards of the region (surface faulting, strong shaking, ground failure, and tsunamis), summarizes methods for characterizing their extent...
Estimation of natural streamflow characteristics in western Colorado
J. E. Kircher, Anne F. Choquette, B. D. Richter
1985, Water-Resources Investigations Report 85-4086
Regression relations were determined for estimating mean annual discharge, mean monthly discharge, minimum and maximum 7-day discharge, flow duration series, and peak discharge for natural streams in western Colorado. Multiple regression analyses were used to determine the best predictive relations for each of the streamflow characteristic; separate relations were developed...
Reconnaissance geochemical exploration of plutons of syenite and shonkinite, southern Asir, Kingdom of Saudi Arabia
W.C. Overstreet, A.B. Assegaff, M.A. Hussain, M.I. Naqvi, G.I. Selner, J.J. Matzko
1985, Open-File Report 85-7
Reconnaissance geochemical exploration for rare metals in plutons of syenite and shonkinite disclosed generally less than 20 ppm Nb in rocks, wadi sediments, and concentrates. The sparsity of Nb is accompanied by low values for La, Sn, W, Y, and Zr and relatively high but insignificant values for Be and...
Controls on ground-water chemistry in the Horse Heaven Hills, south-central Washington
W.C. Steinkampf, Gilbert C. Bortleson, F. A. Packard
1985, Water-Resources Investigations Report 85-4048
Miocene basaltic aquifers are the source of domestic and municipal water, and about 20,000 acre-feet of irrigation water annually, in the Horse Heaven Hills in south-central Washington State. Groundwater chemical variations derive from the hydraulic characteristics is of the geohydrologic system, from groundwater basalt reactions, and from irrigation. Some dissolved...
