Water-level records for the northern High Plains of Colorado, 1973-77
Thomas J. Major, Ronald G. Borman, Kenneth D. Vaught
1977, Open-File Report 77-160
Water-level measurements were made in more than 600 wells during January 1977 in the northern High Plains of Colorado which includes about 9,500 square miles. Most of these wells were irrigation wells, but several stock and government-owned wells were also measured, especially in areas where there is little irrigation. Changes...
Seepage tests on No Name Creek, Colville Indian Reservation, Washington, May 12-13, 1977
Robert D. MacNish
1977, Open-File Report 77-618
To gain information for a water-management situation, a seepage test was performed on May 12-13, 1977, on a reach of No Name Creek on the Colville Indian Reservation in north-central Washington. On May 13, injection of a concentrated brine at the head of the test reach permitted chloride-concentration data to...
Water resources data for Kansas, water year 1976
Water Resources Division, U.S. Geological Survey
1977, Water Data Report KS-76-1
Water resources data for the 1976 water year for Kansas consists of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality in wells. This report contains discharge records for 148 gaging stations; stage and contents...
Ground-water resources of the Riviera Beach area, Palm Beach County, Florida
L. F. Land
1977, Water-Resources Investigations Report 77-47
The principal source of freshwater that has been developed in the Riviera Beach area is the so-called shallow aquifer, which is composed of sand, shells, sandstone, limestone, marl, and occasionally clay strata. Often a stratum contains mixtures of two or more of these materials and occasionally they are cemented. The...
Chemical, isotopic, and gas compositions of selected thermal springs in Arizona, New Mexico, and Utah
Robert H. Mariner, T. S. Presser, William C. Evans
1977, Open-File Report 77-654
Twenty-seven thermal springs in Arizona, New Mexico, and Utah were sampled for detailed chemical and isotopic analysis. The springs issue sodium chloride, sodium bicarbonate, or sodium mixed-anion waters of near neutral (6.2) to alkaline (9.2) pH. High concentrations of fluoride, more than 8 milligrams per liter, occur in Arizona in...
Lateral migration of the Middle Sacramento River, California
James Coble Brice
1977, Water-Resources Investigations Report 77-43
Rates and processes of lateral erosion were studied for the middle Sacramento River between Chico Landing and Colusa, Calif. , a river distance of about 50 miles which is bordered by valuable agricultural land. The study is based on comparison of maps made during 1867-1949 and on aerial photographs made...
Hot springs of the central Sierra Nevada, California
Robert H. Mariner, T. S. Presser, William C. Evans
1977, Open-File Report 77-559
Thermal springs of the central Sierra Nevada issue dilute to slightly saline sodium chloride, sodium bicarbonate, or sodium mixed-anion waters ranging in pH from 6.4 to 9.3. The solubility of chalcedony appears to control the silica concentration in most of the spring waters. Fales Hot Springs may be associated with...
Background studies for appraising subsidence in the Texas Gulf Coast region
B. E. Lofgren
1977, Open-File Report 77-412
Significant ground movement has accompanied the extraction of large quantities of fluids from the subsurface at many localities. The possibility of both horizontal and vertical ground movement--subsidence, fissuring, growth faulting--in the Gulf Coast region, caused by the withdrawal of large volumes of deep formation fluids, is of major concern.Although widespread...
Lithium in the brines of Fish Lake Valley and Columbus Salt Marsh, Nevada
C. L. Smith, Allen L. Meier, H.D. Downey
1977, Open-File Report 77-54
Analyses of waters-from springs in Nevada have led to the identification of an area containing anomalous amounts of lithium northwest of the Clayton Valley-area. Fish Lake Valley and Columbus Salt Marsh contain waters having, relatively high lithium and potassium concentrations. At least a part of these waters is probably derived...
Water-level records for Adams, Larimer, Logan, Morgan, Sedgwick, Washington, and Weld Counties, Colorado, 1973-77
Thomas J. Major, Kenneth D. Vaught
1977, Open-File Report 77-461
Water levels measured during March 1977 in 350 wells tapping alluvial aquifers in Adams, Larimer, Logan, Morgan, Sedgwick, Washington, and Weld Counties, Colo., are included in this report. Water-level records for the 4 preceding years also are included to serve as references illustrating declining or rising water levels.Water-level measurements made...
Clinical methods for the assessment of the effects of environmental stress on fish health
Gary A. Wedemeyer, William T. Yasutake
1977, Technical Paper 89
Clinical methods are presented for biological monitoring of hatchery and native fish populations to assess the effects of environmental stress on fish health. The choice of methods is based on the experience of the authors and the judgment of colleagues at fishery laboratories of the U.S. Fish and Wildlife Service....
Application of a rainfall-runoff model in estimating flood peaks for selected small natural drainage basins in Texas
B.C. Massey, Elmer E. Schroeder
1977, Open-File Report 77-792
A parametric rainfall-runoff simulation model was used to synthesize long-term records of annual peak discharges for small natural drainage basins in Texas. Optimum model-parameter values were determined for each of the 40 basins studied by using short-term rainfall, evaporation, and discharge data. The calibrated model was used in conjunction with...
Analyses of water, core material, and elutriate samples collected near Buras, Louisiana (New Orleans to Venice, Louisiana, Hurricane Protection Project)
Harold A. Leone
1977, Open-File Report 77-310
Eight core-material-sampling sites were chosen by the U.S. Army Corps of Engineers as possible borrow areas for fill material to be used in levee contruction near Buras, La. Eleven receiving-water sites also were selected to represent the water that will contact the porposed levees. Analyses of selected nutrients, metals, pesticides,...
Analyses of water, core material, and elutriate samples collected near Galliano, Louisiana: Larose to Golden Meadow, Louisiana, Hurricane Protection Project
Harold L. Leone
1977, Open-File Report 77-576
Seven core-material-sampling sites were chosen by the U.S. Army Corps of Engineers as possible borrow areas for fill material to be used in levee construction near Galliano La. Four receiving-water sites also were selected to represent the water that will contact the proposed levees. Analyses of selected nutrients, metals, pesticides,...
Computer simulation of two-dimensional unsteady flows in estuaries and embayments by the method of characteristics : Basic theory and the formulation of the numerical method
Chintu Lai
1977, Water-Resources Investigations Report 77-85
Two-dimensional unsteady flows of homogeneous density in estuaries and embayments can be described by hyperbolic, quasi-linear partial differential equations involving three dependent and three independent variables. A linear combination of these equations leads to a parametric equation of characteristic form, which consists of two parts: total differentiation along the bicharacteristics...
