Water quality and bathymetry of Sand Lake, Anchorage, Alaska
Donald E. Donaldson
1976, Open-File Report 76-254
Sand Lake, a dimictic lowland lake in Anchorage, Alaska, has recently become as urban lake. Analyses indicate that the lake is oligotrophic, having low dissolved solids and nutrient concentrations. Snowmelt runoff from an adjacent residential area, however, has a dissolved-solids concentration 10 times that of the main body of Sand...
Preimpoundment water quality of Raystown Branch Juniata River and six tributary streams, south-central Pennsylvania
Donald R. Williams
1976, Water-Resources Investigations Report 76-57
The Raystown Branch Juniata River watershed, which is the main water source for Raystown Lake, is a 960-square-mile (2,490 square kilometres) drainage basin in south-central Pennsylvania. Preimpoundment water-quality data were collected on the Raystown Branch and six tributary st.reams in the basin. Specific conductance values varied inversely with water discharge....
Effects of urbanization on flood characteristics in Nashville-Davidson County, Tennessee
Herman C. Wibben
1976, Water-Resources Investigations Report 76-121
Streamflow data from 14 basins in Davidson County, Tenn., were extended in time by use of a digital model of the hydrologic system. The basins ranged in size from 1.58 to 64.0 square miles and ranged in extent of manmade impervious cover from 3 to 37 percent. The flood-frequency characteristics...
Geohydrology of the Anza-Terwilliger area, Riverside County, California
W. R. Moyle Jr.
1976, Water-Resources Investigations Report 76-10
The Anza-Terwilliger area consists of about 96 square miles (24-9 square kilometres) in the upper parts of the Santa Margarita River and Coyote Creek drainage basins in Riverside County, Calif., about 90 miles (145 kilometres) southeast of Los Angeles. This report deals with geology, steady state and transient state of...
Ground-water records for northeastern Oklahoma : Part 1, records of wells, test-holes, and springs
John S. Havens, DeRoy L. Bergman
1976, Open-File Report 76-890
The U. S. Geological Survey has collected data on Oklahoma's ground-water resources since 1934. Most of these data were collected as part of specific ground-water studies conducted in cooperation with various Federal, State, and local agencies. Although a large amount of ground-water data have been published, they are scattered through a...
Documentation of finite-difference model for simulation of three-dimensional ground-water flow
Peter C. Trescott, S. P. Larson
1976, Open-File Report 76-591
User experience has indicated that the documentation of the model of three-dimensional ground-water flow (Trescott and Larson, 1975) should be expanded. This supplement is intended to fulfill that need. The original report emphasized the theory of the strongly implicit procedure, instructions for using the groundwater-flow model, and practical considerations for...
