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;...
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...
Magnitude and frequency of floods in eastern Oregon
D.D. Harris, L.E. Hubbard
1982, Water-Resources Investigations Report 82-4078
A method for estimating the magnitude and frequency of floods is presented for unregulated streams in eastern Oregon. Equations relating flood magnitude to basin characteristics were developed for exceedance probabilities of 0.5 to 0.01 (2- to 100-year recurrence intervals). Separate equations are presented for four regions: Southeast, Northeast, North Central,...
Methodologies for extraction of dissolved inorganic carbon for stable carbon isotope studies: Evaluation and alternatives
Afifa Afifi Hassan
1982, Water-Resources Investigations Report 82-6
The gas evolution and the strontium carbonate precipitation techniques to extract dissolved inorganic carbon (DIC) for stable carbon isotope analysis were investigated. Theoretical considerations, involving thermodynamic calculations and computer simulation pointed out several possible sources of error in delta carbon-13 measurements of the DIC and demonstrated the need for experimental...
Hydrology of the sand-and-gravel aquifer, southern Okaloosa and Walton Counties, northwest Florida
L. R. Hayes, D. E. Barr
1982, Water-Resources Investigations Report 82-4110
The sand-and-gravel aquifer in southern Okaloosa and Walton Counties, northwest Florida, extends from land surface to depth of 50 to 150 feet. Intervening layers of clay generally separate the aquifer into an unconfined surficial zone, composed principally of fine to medium sand, and a lower confined zone, consisting of variable...
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...
Automation of an ion chromatograph for precipitation analysis with computerized data reduction
Arthur G. Hedley, Marvin J. Fishman
1982, Water-Resources Investigations Report 81-78
Interconnection of an ion chromatograph, an autosampler, and a computing integrator to form an analytical system for simultaneous determination of fluoride, chloride, orthophosphate, bromide, nitrate, and sulfate in precipitation samples is described. Computer programs provided with the integrator are modified to implement ionchromatographic data reduction and data storage. The liquid-flow...
Method for estimating historical irrigation requirements from ground water in the High Plains in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming
Frederick J. Heimes, Richard R. Luckey
1982, Water-Resources Investigations Report 82-40
Historical information on ground-water pumpage for irrigation is required for use with a computer model of the High Plains aquifer. Available historical data on ground-water pumpage in the High Plains were inadequate for use with the computer model. Consequently, a method was developed to estimate historical pumpage data.Two principal components...
Water resources data for Missouri, water year 1981
Water Resources Division, U.S. Geological Survey
1982, Water Data Report MO-81-1
Water resources data for the 1981 water year for Missouri consist of records of stage, discharge, and water quality of lakes and reservoirs; contains records for water discharge at 124 gaging stations; stage and contents at 7 lakes and reservoirs; water quality at 33 gaging stations (including 1 lake); 11...
Flood of June 13-15, 1981, in the Blanchard River basin, northwestern Ohio
E.E. Webber
1982, Water-Resources Investigations Report 82-4044
The flood of June 13-15, 1981, in the Blanchard River basin in northwestern Ohio caused major damage in Findlay, Ottawa, and adjacent rural areas. Approximately 25 percent of Findlay and 55 percent of Ottawa were flooded. Estimated crop damage was $12 million in Hancock Country, $7 million in Wyandot Country,...
Geologic and well-construction data for the H-8 borehole complex near the proposed Waste Isolation Pilot Plant site, southeastern New Mexico
J.G. Wells, S.L. Drellack
1982, Water-Resources Investigations Report 82-4118
The H-8 complex, a group of three closely-spaced boreholes, is located 9 miles south of the proposed Waste Isolation Pilot Plant site in southeastern Eddy County, New Mexico. The holes were drilled during July, August, and September of 1979 to obtain geologic and hydrologic data to better define the regional...
Water-quality characteristics of Everglades National Park, 1959-77, with reference to the effects of water management
Bradley G. Waller
1982, Water-Resources Investigations Report 82-34
The U.S. Geological Survey has collected water-quality data in the Everglades National Park since 1959. Major ions, macronutrients, trace elements, and pesticides are the primary chemical groups analyzed. The period of record and frequency of sampling vary for each chemical group, with the longest record for the major ions and...
