Water-quality investigation, Salinas River, California
George A. Irwin
1976, Water-Resources Investigations Report 76-110
Concentrations of dissolved solids in the Salinas River are variable and range from 164 to 494 milligrams per liter near Bradley and from 170 to 1,090 milligrams per liter near Spreckels. Higher concentrations near Spreckels are caused mainly by sewage inflow about 150 feet (50 meters) upstream. Concentrations of nitrogen,...
Estimating runoff volumes and flood hydrographs in the Colorado River Basin, southern Utah
James H. Eychaner
1976, Water-Resources Investigations Report 76-102
Hydrographs of 364 floods from 18 continuous-record gaging sites in the Colorado River basin in southern Utah were used to define a single relation of flood volume to peak discharge; the standard error of estimate of that relation . is 82 percent. Using the same data, a mean dimensionless hydrograph...
Mapping and measuring land-cover characteristics of New River Basin, Tennessee, using Landsat digital tapes
E. F. Hollyday, S.P. Sauer
1976, Water-Resources Investigations Report 76-106
Land-cover information is needed to select subbasins within the New River basin, Tennessee, for the study of hydrologic processes and also is needed to transfer study results to other sites affected by coal mining. It was believed that data recorded by the first Earth Resources Technology Satellite (Landsat-1) could be...

Geohydrology of the Oklahoma Panhandle, Beaver, Cimarron, and Texas Counties
D.L. Hart, G. L. Hoffman, Robert L. Goemaat
1976, Water-Resources Investigations Report 75-25
The Ogallala aquifer, which consists of semiconsolidated clay, sand, and gravel, is the principal source of ground water in the Oklahoma Panhandle. This aquifer commonly yields 500 to 1,000 gallons per minute (32 to 63 litres per second) and may yield as much as 2,500 gallons per minute (158 litres...

Dissolved solids, hardness, and orthophosphate of surface-water runoff in the Northwest Florida Water Management District
J.E. Earle
1976, Water-Resources Investigations Report 76-16
This atlas consists of three maps that show the general distribution of dissolved solids, hardness, and orthophosphate in the streams and lakes within the Northwest Florida Water Management District. The atlas was prepared in cooperation with the Water Management District to provide pertinent water-quality information relating to the objectives of...
Water-resources data for deep aquifers of eastern Montana
W.B. Hopkins
1976, Water-Resources Investigations Report 76-40
Water from aquifers of Mesozoic and Paleozoic age in eastern Montana is little used. This report presents maps and tables to assist in the evaluation of the water in terms of possible utility. In the southern third of eastern Montana water from the Madison Group or from the Tensleep Sandstone...
Availability of ground water near Carmel, Hamilton County, Indiana
D. C. Gillies
1976, Water-Resources Investigations Report 76-46

1976, Water-Resources Investigations Report 76-12
Several types of ring infiltrometers were used to determine infiltration rates in loessial soil near Scott City, Kansas. Test results were evaluated for consistency, and were compared with infiltration rates in the underlying loess and with hydraulic conductivities in the unsaturated zone.Average daily infiltration rates in the Richfield soil ranged...
