Sediment transport in the Feather River, Lake Oroville to Yuba City, California
George Porterfield, Robert D. Busch, Arvi O. Waananen
1978, Water-Resources Investigations Report 78-20
Regulation of the Feather River by Oroville Dam and reservoir in northeast California (beginning in 1967) changed the streamflow and sediment discharge downstream from the dam. Changes in channel geometry to adjust to the new regimen were still in process in 1975. Streamflow and sediment concentration and discharge had decreased....
Predictive analyses of ground-water discharges in the Willow Creek Watershed, northeast Nebraska
Jack T. Dugan, Eric G. Lappala
1978, Water-Resources Investigations Report 78-67
Ground-water discharge to Willow Creek, which drains a 204 mi2 watershed in northeast Nebraska was predicted for six combinations of conditions of climate and ground-water development. A digital model of the ground water/surface-water system was stressed with recharge and withdrawal functions determined from a linear reservoir model of the soil...
Gravity survey of the Tularosa Valley and adjacent areas, New Mexico
D.L. Healey, R. R. Wahl, F. E. Currey
1978, Open-File Report 78-309
The gravity survey of the Tularosa Valley and adjacent areas is a compilation of gravity data acquired from several sources and reduced to the 1971 International Gravity Standardization Network datum. In addition, three local surveys were made that helped to fill in gaps in the gravity coverage. The resulting complete...
Research and development program for outer continental shelf oil and gas operations, report for fiscal year 1978
John B. Gregory
1978, Open-File Report 78-902
This report summarizes the contract research program in support of the Geological Survey's Outer Continental Shelf oil and gas operations. The program is technological, though certain environmental investigations are being conducted as a necessary adjunct. The program manager provides a focal point for communicating with the research community in both...
