Numerical model of the salt-wedge reach of the Duwamish River estuary, King County, Washington
Edmund A. Prych, W.L. Haushild, J.D. Stoner
1976, Professional Paper 990
A numerical model of a salt-wedge estuary developed by Fischer (1974) has been expanded and used to calculate the distributions of salinity, temperature, chlorophyll a concentration, biochemical oxygen demand, and dissolved-oxygen concentration in the Duwamish River estuary, King County, Wash. The model was used to predict the dissolved-oxygen concentrations in...

Reconnaissance water sampling for radium-226 in central and northern Florida, December 1974-March 1976
G. A. Irwin, C. B. Hutchinson
1976, Water-Resources Investigations Report 76-103
Analyses of 115 water samples collected from December 1974 through March 1976 in eight Florida Counties indicated that 22 samples (19 percent) had radium-226 activities equal to or in excess of 3 piC/liter (picocuries per liter), the concentration limit recommended for drinking water by the U.S. Public Health Service. The...
Distribution and trend of nitrate, chloride, and total solids in water in the Magothy aquifer in southeast Nassau County, New York, from the 1950's through 1973
Henry F. Ku, Dennis J. Sulam
1976, Water-Resources Investigations Report 76-44
Concentrations of nitrate, chloride, and total solids in water in the Magothy aquifer, southeast Nassau County, N.Y., show a steadily increasing trend from the early 1950 's through 1973. Vertical distribution of nitrate, chloride, and total-solids concentrations as shown in cross sections of the study area indicate downward movement of...

Sediment discharge from highway cut-slopes in the Lake Tahoe Basin, California, 1972-74
Carl G. Kroll
1976, Water-Resources Investigations Report 76-19
Streamflow and fluvial-sediment discharge data were collected at selected streams and highway gutters in the Lake Tahoe basin to determine the extent of erosion from highway cuts and to attempt to evaluate the effects of various land-treatment practices to reduce erosion.Estimate of long-term annual total-sediment discharge from six streams into...
Lakes Marion-Moultrie stream system investigation, South Carolina : Part II-Simulation Studies
H.H. Jeffcoat, M.E. Jennings, D.L. Collins, J.O. Shearman
1976, Water-Resources Investigations Report 76-11
A stream-reservoir model was developed to simulate the operation of the Lakes Marion-Moultrie, South Carolina, reservoir system. The reservoir system is operated under the assumption of a 3-day prior knowledge of inflows. This information is attainable from the ooperational reservoir-inflow forecasting model developed in the Part I report. The model,...
Maps showing ground-water conditions in the San Bernardino Valley area, Cochise County, Arizona -- 1975
R. P. Wilson
1976, Water-Resources Investigations Report 76-81
Arizona is divided into 67 ground-water areas, and individual areas are selected for intensive data collection once every 6 years. The data collected in the San Bernardino Valley area are given on maps that show depth to water, well depth, and altitude of the water level; and dissolved-solids and fluoride...

Hydrologic relations between lakes and aquifers in a recharge area near Orlando, Florida
William F. Lichtler, G.H. Hughes, F. L. Pfischner
1976, Water-Resources Investigations Report 76-65
The three lakes investigated in Orange County, Florida, gain water from adjoining water-table aquifer and lose water to Floridan aquifer by downward leakage. Net seepage (net exchange of water between lake and aquifers) can be estimated by equation S = AX + BY, where S is net seepage, X represents...
