Dye tracing techniques used to determine ground-water flow in a carbonate aquifer system near Elizabethtown, Kentucky
D. S. Mull, J. L. Smoot, T.D. Liebermann
1988, Water-Resources Investigations Report 87-4174
Because of the vulnerability of karst aquifers to contamination and the need for water managers to know recharge areas and groundwater flow characteristics for springs and wells used for public water supply, qualitative and quantitative dye tracing techniques were used during a groundwater investigation in the Elizabethtown area, Hardin County,...
Low-flow profiles of the upper Oconee River and tributaries in Georgia
R.F. Carter, E. H. Hopkins, H.A. Perlman
1988, Water-Resources Investigations Report 88-4048
Low flow information is provided for use in an evaluation of the capacity of streams to permit withdrawals or to accept waste loads without exceeding the limits of State water quality standards. The purpose of this report is to present the results of a compilation of available low flow data...
Sedimentation and water quality in the West Branch Shade River basin, Ohio, 1983-85
C. J. Oblinger Childress, R.L. Jones
1988, Water-Resources Investigations Report 87-4262
Loss of channel conveyance from deposition of sediment from abandoned surface mines in the West Branch Shade River basin has resulted in frequent flooding. In addition, water quality in the West Branch Shade River and some of its tributaries is typical of streams affected by acid mine drainage. About 938...
Habitat Suitability Index Models: American eider (breeding)
A. K. Blumton, Ray B. Owen Jr., William B. Krohn
1988, FWS/OBS 82/10.149
INTRODUCTION The common eider (Somateria mollissima) consists of five subspecies; four are found in North America (Palmer 1976). Six management populations of common eiders have recently been defined in eastern Canada and the United States (Reed and Erskine 1986). The American edier (S. mollissima dresseri), of which three populations are recognized...
Statistical summaries of streamflow records in Oklahoma and parts of Arkansas, Missouri, and Texas through 1984
D. C. Heimann, R. L. Tortorelli
1988, Water-Resources Investigations Report 87-4205
Statistical summaries of streamflow records through 1984 for gaging stations in Oklahoma and parts of adjacent states are presented in this report. Records are presented for 148 stations with at least 10 years of unregulated or regulated streamflow. Streamflow at 70 of the stations is regulated for certain perdiods. Data...
Simulation of quantity and quality of storm runoff for urban catchments in Fresno, California
J. R. Guay, P. E. Smith
1988, Water-Resources Investigations Report 88-4125
Rainfall-runoff models were developed for a multiple-dwelling residential catchment (2 applications), a single-dwelling residential catchment, and a commercial catchment in Fresno, California, using the U.S. Geological Survey Distributed Routing Rainfall-Runoff Model (DR3M-II). A runoff-quality model also was developed at the commercial catchment using the Survey 's Multiple-Event Urban Runoff Quality...
Mines, prospects, and mineral sites, wilderness and RARE II areas, White Mountain National Forest, New Hampshire
G. C. Gazdik, Gazdik Harris, R. A. Welsh, V. P. Girol
1988, Miscellaneous Field Studies Map 1594-E
The Wilderness Act (Public Law 88-577, September 3, 1964) and related acts require the U.S. Geological Survey and the U.S. Bureau of Mines to survey certain areas on Federal lands to determine their mineral value, if any, that may be present. Results must be made available to the public and...
Description and hydrogeologic evaluation of nine hazardous-waste sites in Kansas, 1984-86
R. J. Hart, T.B. Spruill
1988, Water-Resources Investigations Report 88-4015
Wastes generated at nine hazardous-waste sites in Kansas were disposed in open pits, 55-gal drums, or large storage tanks. These disposal methods have the potential to contaminate groundwater beneath the sites, the soil on the sites, and nearby surface water bodies. Various activities on the nine sites included production of...
Habitat Suitability Index Models: Black-bellied whistling-duck (breeding)
Paul M. McKenzie, Phillip J. Zwank
1988, FWS/OBS 82/10.150
A review and synthesis of existing information were used to develop a model for evaluating the quality of habitat for breeding black-bellied whistling-ducks. The model is scaled to produce an index between 0.0 (unsuitable habitat) to 1.0 (optimal habitat). Habitat suitability index models are designed to be used with Habitat...
Estimating flood hydrographs and volumes for Alabama streams
D.A. Olin, J.B. Atkins
1988, Water-Resources Investigations Report 88-4041
The hydraulic design of highway drainage structures involves an evaluation of the effect of the proposed highway structures on lives, property, and stream stability. Flood hydrographs and associated flood volumes are useful tools in evaluating these effects. For design purposes, the Alabama Highway Department needs information on flood hydrographs and...
Habitat Suitability Index Models: Diamondback terrapin (nesting) - Atlantic coast
William M. Palmer, Carroll L. Cordes
1988, FWS/OBS 82/10.151
A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model for the diamondback terrapin (Malaclemys terrapin). The model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index between 0.0 (unsuitable habitat) to 1.0 (optimum...
A modification of the U.S. Geological Survey one-sixth order semiquantitative spectrographic method for the analysis of geologic materials that improves limits of determination of some volatile to moderately volatile elements
D.E. Detra, Elmo F. Cooley
1988, Circular 996
A modification of the one-sixth order semi-quantitative emission spectrographic method for the analysis of 30 elements in geologic materials (Grimes and Marranzino 1968) improves the limits of determination of some volatile to moderately volatile elements. The modification uses a compound-pendulum-mounted filter to regulate the amount of emitted light passing into...
Potential hydrologic effects of a drainage system in McMillan delta and water impoundment in Brantley Reservoir, Eddy County, New Mexico
T. M. Crouch, G. E. Welder
1988, Water-Resources Investigations Report 88-4054
Construction of a proposed drainage system could result in a moderate flow increase in the Pecos River downstream from the McMillan delta. The potential effect of a new line channel of the Pecos River in McMillan delta in southeastern New Mexico would be an increase of less than 11,000 acre-ft/year....
Recharge to the Eagle Valley ground-water basin by streamflow in Vicee Canyon, west-central Nevada
D. K. Maurer, J.M. Fischer
1988, Water-Resources Investigations Report 88-4158
Recharge to groundwater could be increased by adding imported water to natural surface water flow in Vicee Canyon, in Eagle Valley, Nevada, where municipal pumping has caused as much as 50 ft of water level decline since 1972. Measurements of infiltration rates, percolation rates, and hydraulic conductivity indicate that the...
Geohydrology of the Flathead Indian Reservation, northwestern Montana
S.E. Slagle
1988, Water-Resources Investigations Report 88-4142
The geohydrology of the Flathead Indian Reservation was studied to provide information needed to formulate groundwater development plans. Bedrock in the area consists predominantly of slightly metamorphosed carbonate and fine-grained clasitc rocks of the Precambrian Belt Supergroup. Valley-fill deposits consist of alluvium of Holocene age; glacial and glaciolacustrine boulders, cobbles,...
U.S. Geological Survey ground-water studies in Nevada
M. D. Dettinger, A. S. Van Denburgh
1988, Open-File Report 88-119
Groundwater is an important natural resource in Nevada. In 1985, groundwater provided 24% of the total water withdrawn, and supplied about 40% of the State 's population. Public supply and self-supplied domestic use accounted for about 12% of the groundwater withdrawn, and self-supplied industrial and mining use was about 3%....
