Habitat Suitability Index Models: Blue Grouse
Richard L. Schroeder
1984, FWS/OBS 82/10.81
A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model for the blue grouse (Dendragapus obscurus). 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...
Gazetteer of hydrologic characteristics of streams in Massachusetts — Coastal river basins of the South Shore and Buzzards Bay
S. W. Wandle, M. A. Morgan
1984, Water-Resources Investigations Report 84-4288
The coastal river basins include the minor river basins draining into Massachusetts Bay along the South Shore or into Buzzards Bay. The larger of these basins are the North, South, Jones, Wareham, Weweantic, Mattapoisett, Acushnet, and Slocums River basins. Drainage areas, using the latest available 1:24,000 scale topographic maps, were...
Water quality of the tidal Potomac River and Estuary; hydrologic data report supplement, 1979 through 1981 water years
R.H. Coupe, W.E. Webb
1984, Open-File Report 84-132
This report is a companion report to the U.S. Geological Survey 1979, 1980, and 1981 Hydrologic Data Reports of the tidal Potomac River and Estuary. It contains values of biochemical oxygen demand and specific rate constants, incident light and light attenuation measurements; numbers of phytoplankton, fecal coliform and fecal streptococci,...
Habitat Suitability Index Models: Larval and juvenile red drum
Jack Buckley
1984, FWS/OBS 82/10.74
A review and synthesis of existing information were used to develop a habitat model for larval and juvenile red drum. The model is scaled to produce an index of habitat suitability between 0 (unsuitable habitat) and 1 (optimally suitable habitat) for estuarine areas along the Gulf of Mexico and Atlantic...
Evaluation of the hydrologic system and potential effects of mining in the Dickinson lignite area, eastern slope and western Stark and Hettinger counties, North Dakota
C. A. Armstrong
1984, Water-Resources Investigations Report 84-4194
The investigation of the water resources of the Dickinson lignite area, an area of about 500 square miles, was undertaken to define the hydrologic system of the area and to project probable effects of coal mining on the system.Aquifers occur in sandstone beds in: the Fox Hills Sandstone and the...
Nitrate in the Columbia Aquifer, central Delmarva Peninsula, Maryland
L. J. Bachman
1984, Water-Resources Investigations Report 84-4322
A study of nitrate in water from 604 wells tapping the Columbia aquifer on the Delmarva Peninsula in eastern Maryland describes the factors that affect nitrate variability. Samples were collected from 196 randomly selected wells and analyzed for nitrogen species. Many were also analyzed for major ions. In addition, results...
Hydrologic characteristics of Nebraska soils
Jack T. Dugan
1984, Water Supply Paper 2222
The influence of the physical characteristics of soil on hydrology is frequently neglected. In this report, the effects of five characteristics on the hydrologic responses of soils in Nebraska are evaluated quantitatively, soils are grouped through use of a simplified coding system according to similarities in hydrologic responses, and are...
