Data for calibrating unsteady-flow sediment-transport models, East Fork River, Wyoming, 1975
Holly A. Mahoney, Edmund D. Andrews, William W. Emmett, Luna Bergere Leopold, Robert H. Meade, Robert M. Myrick, Carl F. Nordin
1976, Open-File Report 76-22
In 1975, data to calibrate a one-dimensional unsteady-flow and sediment-transport routing model were collected on a reach of the East Fork River of western Wyoming. The reach, 3.1 miles (5 kilometers) in length, wan immediately upstream from a previously established bedload sampling station. Nineteen channel cross sections were sounded at...
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...
A hydrologic description of Keystone Lake near Tampa, Florida
R.C. Reichenbaugh
1976, Water-Resources Investigations Report 76-124
The terrain around Keystone Lake, a 388-acre lake in northwest Hillsborough County, Florida, near the Cosme well field, is dotted with sinks that promote leakage from the surficial aquifer to the underlying Floridan aquifer. The lake, an integral part of the Brooker Creek channel, receives overland runoff from cypress swamps,...
Hydrologic analysis and river-quality data programs
Walter G. Hines, David A. Rickert, Stuart W. McKenzie
1976, Circular 715-D
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...
Summary of some current and possible future environmental problems related to geology and hydrology at Memphis, Tennessee
William Scott Parks, Richard W. Lounsbury
1976, Water-Resources Investigations Report 76-4
This report summarizes information concerning many aspects of the geology and hydrology at Memphis, Tenn. It also outlines some of the current problems related to the local geology and hydrology or ones that may arise as a result of urbanization and industrialization of the area. The city is in the...
Water availability, quality, and use in Alaska
G. O. Balding
1976, Open-File Report 76-513
The Alaska Water Assessment, sponsored by the Water Resources Council, is a specific problem analysis for Alaska of the National Assessment of Water and Related Land Resources. The assessment addresses water and water-related land problems, present and future. It was felt that a supplementary report, as a part of the...
Predicted effects of a proposed water-resources management plan in the lower San Luis Rey River Valley, California, using digital ground-water flow models
James A. Skrivan
1976, Open-File Report 76-754
A proposed plan for water-resource management in the lower San Luis Rey River valley, Calif. has been evaluated using digital models of ground-water flow. Two projections of water-level changes and salt balance in 1977 were made. The first projection used 1972 climatic and pumping conditions. The second projection used these...
Digital-model analysis to predict water levels in a well field near Columbus, Indiana
Michael Planert
1976, Water-Resources Investigations Report 76-63
Columbus, Indiana, obtains its water supply from six municipally owned wells southwest of the city. The wells are screened in an outwash sand and gravel aquifer that was deposited by glacial melt water in a preglacial bedrock valley. The well field is midway between the East Fork White River and...
