Flood profiles in the Calapooya Creek basin, Oregon
John Friday
1982, Open-File Report 82-439
Water-surface profiles were computed for a 19.4-mile reach of Calapooya Creek in Douglas County, Oregon. The data will enable the county to evaluate flood hazards in the floodprone areas in the reach. Profiles for floods having recurrence intervals of 2, 10, 50, 100, and 500 years are shown in graphic...
Delineation and hydrologic effects of a gasoline leak at Stovepipe Wells Hotel, Death Valley National Monument, California
A. Buono, Elaine M. Packard
1982, Water-Resources Investigations Report 82-45
Ground water is the only local source of water available to the Stovepipe Wells Hotel facilities of the Death Valley National Monument, California. A leak in a service station storage tank caused the formation of a gasoline layer overlying the water table, creating the potential for contamination of the water...
Thermal springs in the Boise River basin, south-central Idaho
R.E. Lewis, H.W. Young
1982, Water-Resources Investigations Report 82-4006
The Boise River Basin, characterized by steep, rugged mountains and narrow river valleys, drains an area of about 2,680 square miles in south-central Idaho. Granitic rocks of the Idaho batholith predominate in the basin. Temperature of waters from thermal springs in the basin range from 33 degrees to 87 degrees...
Evaluation of a predictive ground-water solute-transport model at the Idaho National Engineering Laboratory, Idaho
Barney D. Lewis, Flora J. Goldstein
1982, Water-Resources Investigations Report 82-25
Aqueous chemical and radioactive wastes discharged to shallow ponds and to shallow or deep wells on the Idaho National Engineering Laboratory (INEL) since 1952 have affected the quality of the ground water in the underlying Snake River Plain aquifer. The aqueous wastes have created large and laterally dispersed concentration plumes...
Geologic map of the Wenatchee 1:100,000 Quadrangle, central Washington
R. W. Tabor, R. B. Waitt Jr., V. A. Frizzell Jr., D. A. Swanson, G. R. Byerly, R. D. Bentley
1982, IMAP 1311
The rocks and deposits within the Wenatchee quadrangle can be grouped into six generalized units: (1) Precambrian(?) Swakane Biotite Gneiss in the northeastern part of the quadrangle and the probable Jurassic low-grade metamorphic suite, mostly composed of the Easton Schist, in the southwestern part; (2) the Mesozoic Ingalls Tectonic Complex;...
A three-dimensional ground-water-flow model modified to reduce computer-memory requirements and better simulate confining-bed and aquifer pinchouts
P.P. Leahy
1982, Water-Resources Investigations Report 82-4023
The Trescott computer program for modeling groundwater flow in three dimensions has been modified to (1) treat aquifer and confining bed pinchouts more realistically and (2) reduce the computer memory requirements needed for the input data. Using the original program, simulation of aquifer systems with nonrectangular external boundaries may result...
Results of deep-well injection testing at Mulberry, Florida
John J. Hickey, W.E. Wilson
1982, Water-Resources Investigations Report 81-75
At the Kaiser Aluminum and Chemical Corporation plant, Mulberry, Fla., high-chloride, acidic liquid wastes are injected into a dolomite section at depths below about 4,000 feet below land surface. In 1975, a satellite monitor well was drilled 2,291 feet from the injection well and a series of three injection tests...
Model modifications for simulation of flow through stratified rocks in eastern Ohio
J. O. Helgesen, A. C. Razem, S. P. Larson
1982, Water-Resources Investigations Report 82-4019
A quasi three-dimensional groundwater flow model is being used as part of a study to determine impacts of coal-strip mining on local hydrologic systems. Modifications to the model were necessary to simulate local hydrologic conditions properly. Perched water tables required that the method of calculating vertical flow rate be changed....
Preliminary evaluation of the ground-water-flow system in the Twin Cities Metropolitan area, Minnesota
John H. Guswa, Donald I. Siegel, Daniel C. Gillies
1982, Water-Resources Investigations Report 82-44
A preliminary quasi-three-dimensional finite-difference ground-water-flow model of the seven-county Twin Cities Metropolitan area was constructed and used to evaluate parameter sensitivity and adequacy of available data. Fourteen geologic units that underlie the study area were grouped into nine hydr,bgeologic units and were incorporated into a five-layer model. The layers in...
Progress report on geologic studies of the Ranger orebodies, Northern Territory, Australia
J. T. Nash, David Frishman
1982, Open-File Report 82-936
The Ranger No. 1 and No. 3 orebodies contain about 124,000 tonnes U3O8 in highly chloritized metasediments of the lower Proterozoic Cahill Formation within about 500 m of the projected sub-Kombolgie Formation unconformity. In both orebodies, oxidized and reduced uranium minerals occur chiefly in quartzose schists that have highly variable...
Water resources of Borrego Valley and vicinity, California: Phase 1— Definition of geologic and hydrologic characteristics of the basin
W. R. Moyle
1982, Open-File Report 82-855
This report is phase 1 of a 3-phase study and includes information needed to build a digital hydrologic model of Borrego Valley. It includes sources and amounts of recharge water to the basin, areas of water withdrawal, total ground water in storage at steady-state conditions (1945), net ground-water depletion, grid...
Small-stream flood investigations in Minnesota, October 1958 to September 1980
Kurt T. Gunard, C.J. Smith
1982, Open-File Report 82-433
An investigation of flood flows from small drainage basins in Minnesota is being made to aid in the design of bridges, culverts and other highway drainage structures. Results of the investigation provide peak-flow data on streams generally with drainage areas less than 200 square miles, placing particular emphasis on those...
Algal conditions in the Caloosahatchee River (1975-79), Lake Okeechobee to Franklin Lock, Florida
Benjamin F. McPherson, Henry R. La Rose
1982, Water-Resources Investigations Report 81-81
Maximum numbers of suspended algae occurred in late spring and early summer, in each of the years 1975-79, in the Caloosahatchee River. Numbers exceeded 100,000 cells per milliliter at all stations sometime during the study. Concentrations decreased during late summer and autumn and were low during winter, except in January...
Hydrology of the Prairie Dog Creek drainage basin, Rosebud and Big Horn Counties, Montana
N. E. McClymonds
1982, Water-Resources Investigations Report 81-37
The Prairie Dog Creek drainage basin in southeastern Montana was investigated during 1978-79 to assess the surface-water and ground-water resources and the quality of water in an area having coal-mining potential. The area, a 24.2-square-mile basin, is located 30 miles southwest of Ash-land, Montana. The principal mineable coal is the...
Ground-water applications of remote sensing
Gerald K. Moore
1982, Open-File Report 82-240
Remote sensing can be used as a tool to inventory springs and seeps and to interpret lithology, structure, and ground-water occurrence and quality. Thermograms are the best images for inventory of seeps and springs. The steps in aquifer mapping are image analysis and interpretation and ground-water interpretation. A ground-water interpretation...
