Side-scan sonograph data from eastern Rhode Island Sound and Vineyard Sound, Massachusetts
Charles J. O’Hara
1980, Open-File Report 80-283
Two hundred twenty-four kilometers of closely spaced side-scan sono­graph data have been collected from eastern Rhode Island Sound and Vineyard Sound, Mass., by the U.S. Geological Survey in cooperation with the New England Division of the U.S. Army Corps of Engineers. These data were obtained during the August 1976 cruise...
A statistical analysis of the quality of surface water in Nebraska
R. A. Engberg
1980, Water-Resources Investigations Report 80-43
This report provides descriptive statistics for 29 chemical or biological constituents for 109 stream sites in Nebraska sampled by the U.S. Geological Survey beginning in 1946. Also provided for each site are regression equations relating specific conductance to each of 12 chemical constituents and a regression equation relating specific conductance...
Baseline water quality of Schmidt, Hornbeam, and Horseshoe Lakes, Dakota County, Minnesota
G. A. Payne
1980, Water-Resources Investigations Report 80-3
Three lakes in Dakota County were sampled five times during an 18-month period to determine baseline water quality prior to construction of an interstate highway. Results of physical measurements and chemical analyses showed that the lakes were shallow, nonstratified, and nutrient enriched. Considerable seasonal variations in dissolved solids, nutrient, and...
Calibration of a distributed routing rainfall-runoff model at four urban sites near Miami, Florida
W. Harry Doyle Jr., Jeffrey E. Miller
1980, Water-Resources Investigations Report 80-1
Urban stormwater data from four Miami, Fla. catchments were collected and compiled by the U.S. Geological Survey and were used for testing the applicability of deterministic modeling for characterizing stormwater flows from small land-use areas. A description of model calibration and verification is presented for: (1) A 40.8 acre single-family...
U.S. Geological Survey role in earthquake prediction
David P. Hill
1980, Open-File Report 80-144
Work in the Seismology Branch on the problem of earthquake prediction is based primarily on the recording and analysis of seismic (elastic) waves in the Earth generated either by earthquakes themselves or by artificial sources such as quarry blasts or explosions detonated in drill holes. At the present time this...
Water resources of the Cook Inlet Basin, Alaska
Geoffrey W. Freethey, David R. Scully
1980, Hydrologic Atlas 620
Ground-water and surface-water systems of Cook Inlet basin, Alaska, are analyzed. Geologic and topographic features that control the movement and regional availability of ground water are explained and illustrated. Five aquifer systems beneath the most populous areas are described. Estimates of ground-water yield were determined for the region by using...
Approximate water-level changes in wells in the Chicot and Evangeline aquifers in the Houston-Galveston region, Texas, 1977-80 and 1979-80
R.K. Gabrysch, C.E. Ranzau Jr.
1980, Open-File Report 80-337
This report, which was prepared in cooperation with the cities of Houston and Galveston, the Harris Galveston Coastal Subsidence Distract, and the Texas Department of Water Resources, presents data on water-level changes during 1977-80 and 1979-80 in the Chicot and Evangelina aquifers (figs. 1-4).  During these periods, ground water pumping...
Preliminary investigation of a shallow ground-water flow system associated with Connetquot Brook, Long Island, New York
Keith R. Prince
1980, Water-Resources Investigations Report 80-47
Under natural conditions, about 95 percent of the flow in Long Island streams is derived from ground-water seepage. The ground-water system that feeds the streams is a shallow subsystem that overlies the regional subsurface flow system. The Connetquot Brook basin was selected for study because it has not been appreciably...
