Flood frequency: expected and unexpected probabilities
D. M. Thomas
1976, Open-File Report 76-775
Flood-frequency curves may be defined either with or without an ' expeced probability ' adustment; and the two curves differ in the way that they attempt to average the time-sampling uncertainties. A curve with no adustment is shown to estimate a median value of both discharge and frequency of occurrence,...
A model for calculating effects of liquid waste disposal in deep saline aquifer
Inc. Intercomp Resource Development and Engineering
1976, Water-Resources Investigations Report 76-61
Injection of liquid industrial wastes into confined underground saline aquifers can offer a good disposal alternative from both environmental and economic considerations. One of the needs in choosing from among several disposal alternatives is a means of evaluating the influence such an injection will have on the aquifer system. This...
Water-quality investigation, Eel River, California
George A. Irwin
1976, Water-Resources Investigations Report 76-5
This report summarizes selected water-quality data collected in the Eel River, Calif., during a reconnaissance study from November 1971 through January 1975. It also includes a summary of the major inorganic chemical data collected near Dos Rios, at South Fork, and at Scotia since the early 1950's. The recent reconnaissance...
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,...
Magnitude and frequency of floods in North Carolina, technique for estimating the magnitude and frequency of floods on natural streams in North Carolina
N.M. Jackson Jr.
1976, Water-Resources Investigations Report 76-17
Methods are provided to estimate the magnitude and frequency of floods on natural North Carolina streams with drainage areas greater than 0.5 square mile (1.3 square kilometers). For 257 gaged sites, the magnitudes of floods having recurrence intervals from 2 to 100 years are provided in tables. For ungaged sites,...
Technique for estimating magnitude and frequency of floods in Kentucky
Curtis H. Hannum
1976, Water-Resources Investigations Report 76-62
Flood magnitude and frequency relations applicable to unregulated stream in Kentucky are based on flood data at 117 gaging stations in Kentucky and 14 in adjacent states having 10 or more years of record. Equations that related flood magnitude and frequency to contributing drainage area in 16 geographic areas may...
Measurement and prediction of sediment yields in Wisconsin streams
S. M. Hindall
1976, Water-Resources Investigations Report 75-54
Sediment data of some form have been collected by the U.S. Geological Survey at 118 stream-gaging sites throughout Wisconsin, beginning in 1935. The average concentration of suspended sediment for Wisconsin streams is low in comparison with that of many streams in the United States—110 milligrams per litre for Wisconsin, as...
