Levels of lakes in the north Kenai area, Alaska 1970 to 1992
B. J. Bailey, J. A. McIntire
1993, Open-File Report 93-644
The water-surface elevations of 12 lakes near Kenai and Nikiski, Alaska, were measured periodically from 1970 through 1992 using differential leveling techniques. The study was done in cooperation with the Alaska Department of Natural Resources, to help determine seasonal and long-term changes in water storage. Hydrographs accompanied by tables show...
The Effect of mining and related activities on the sediment-trace element geochemistry of Lake Coeur d'Alene, Idaho, U.S.A.; Part II, Subsurface sediments
A. J. Horowitz, K. A. Elrick, J. A. Robbins, R.B. Cook
1993, Open-File Report 93-656
During the summer of 1990, 12 gravity cores were collected in Lake Coeur d'Alene, Idaho, at various depths and in a variety of depositional environments. All core subsamples were analyzed to determine bulk chemistry and selected subsamples were analyzed for trace-element partitioning and (137)Cs activity. The purpose of these analyses...
Statistical summaries of streamflow data for selected gaging stations on and near the Idaho National Engineering Laboratory, Idaho, through September 1990
M. A. J. Stone, Larry J. Mann, L.C. Kjelstrom
1993, Water-Resources Investigations Report 92-4196
Statistical summaries and graphs of streamflow data were prepared for 13 gaging stations with 5 or more years of continuous record on and near the Idaho National Engineering Laboratory. Statistical summaries of streamflow data for the Big and Little Lost Rivers and Birch Creek were analyzed as a requisite for...
TRIM—3D: a three-dimensional model for accurate simulation of shallow water flow
Vincenzo Casulli, Enrico Bertolazzi, Ralph T. Cheng
1993, Conference Paper, Hydraulic Engineering
A semi-implicit finite difference formulation for the numerical solution of three-dimensional tidal circulation is discussed. The governing equations are the three-dimensional Reynolds equations in which the pressure is assumed to be hydrostatic. A minimal degree of implicitness has been introduced in the finite difference formula so that the resulting algorithm...
Map showing sediment isopachs in the deep-sea basins of the Pacific Continental Margin, Strait of Juan de Fuca to Cape Mendocino
J.V. Gardner, D.A. Cacchione, D.E. Drake, B. D. Edwards, M.E. Field, M. A. Hampton, Herman A. Karl, Neil H. Kenyon, D.G. Masson, D. S. McCulloch, M. S. Grim
1993, IMAP 2091-A
The U.S. Geological Survey conducted a series of cruises, EEZSCAN 84 (EEZ-SCAN 84 Scientific Staff, 1986), to collect reconnaissance data on the newly proclaimed Exclusive Economic Zone (EEZ), the area out to 200 nautical miles from the coastline of the United States. The cruises systematically surveyed the entire conterminous United...
Geohydrology and simulation of flow and water levels in the aquifer system in the Mud Lake area of the eastern Snake River plain, eastern Idaho
Joseph M. Spinazola
1993, Water-Resources Investigations Report 93-4227
Water users rely on surface water and ground water to irrigate crops and to maintain lakes on wildlife refuges in the 2,200-square-mile Mud Lake study area. Ground-water development between the late 1970's and 1989 increased withdrawals from about 240,000 acre-feet in 1983 to about 370,000 acre-feet in 1990. Concurrent with...
Simulation of changes in water levels and ground-water flow in response to water-use alternatives in the Mud Lake area, eastern Snake River plain, eastern Idaho
Joseph M. Spinazola
1993, Water-Resources Investigations Report 93-4228
Water users rely on surface and ground water to irrigate crops and maintain wildlife refuges in the 2,200-square-mile Mud Lake study area. Water managers need the ability to evaluate the effects of water-use changes on the future supply of surface and ground water. A five-layer, three-dimensional, finite-difference, numerical ground-water flow...
