John L. Fio, Roger Fujii
1988, Open-File Report 88-458
Methods to determine soluble concentrations of selenite, selenate, and organic selenium were compared on saturation extracts of soil samples collected from three sites on the Panache Creek alluvial fan in the western San Joaquin Valley, California. The methods were used in combination with hydridegeneration atomic-absorption spectrometry for detection of selenium...

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...
Evaluation of the flood hydrology in the Colorado Front Range using precipitation, streamflow, and paleoflood data for the Big Thompson River basin
R.D. Jarrett, J. E. Costa
1988, Water-Resources Investigations Report 87-4117
A multidisciplinary study of precipitation and streamflow data and paleohydrologic studies of channel features was made to analyze the flood hydrology of foothill and mountain streams in the Front Range of Colorado, with emphasis on the Big Thompson River basin, because conventional hydrologic analyses do not adequately characterize the flood...
Effects of coal mine drainage on the water quality of small receiving streams in Washington, 1975-77
F. A. Packard, E.L. Skinner, L. A. Fuste
1988, Water-Resources Investigations Report 85-4274
Drainage from abandoned coal mines in western and central Washington has minimal environmental impact. Water quality characteristics that have the most significant environmental impact are suspended sediment and turbidity. Water quality data from 51 abandoned coal mines representing 11 major coal bearing areas indicate that less than 1% of the...

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...
Nomenclature of regional hydrogeologic units of the Southeastern Coastal Plain aquifer system
J. A. Miller, R.A. Renken
1988, Water-Resources Investigations Report 87-4202
Clastic sediments of the Southeastern Coastal Plain aquifer system can be divided into four regional aquifers separated by three regional confining units. The four regional aquifers have been named for major rivers that cut across their outcrop areas and expose the aquifer materials. From youngest to oldest, the aquifers are...
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...
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...
Geohydrology and susceptibility of major aquifers to surface contamination in Alabama; area 13
W. S. Mooty
1988, Water-Resources Investigations Report 88-4080
The geohydrology and susceptibility to surface contamination of the major aquifers in Area 13--Baldwin and Mobile Counties Alabama--are described. Within this area are two major aquifers. The Pliocene-Miocene aquifer occurs throughout the study area. The Alluvial-Coastal aquifer is found near the major rivers and coastal areas and overlies the Pliocene-Miocene...
Potential effects of surface coal mining on the hydrology of the upper Otter Creek-Pasture Creek area, Moorhead coal field, southeastern Montana

1988, Water-Resources Investigations Report 88-4187
The combined upper Otter Creek-Pasture Creek area, south of Ashland, Montana, contains large reserves of Federal coal for potential lease sale. A hydrologic study was conducted in the area to describe existing hydrologic systems and generalized groundwater quality, to assess potential effects of surface mining on local water resources, and...

Potential flood and debris hazards at Katherine Landing and Telephone Cove, Lake Mead National Recreation Area, Mohave County, Arizona
Otto Moosburner
1988, Water-Resources Investigations Report 87-4081
Katherine Landing is a recreation site on the east shore of Lake Mohave, an impoundment on the Colorado River southeast of Las Vegas, Nevada. With proper inspection and maintenance, the present (1979) channel and diking system at Katherine Landing is judged adequate to confine and restrain floods up to 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...
