AQUIFEM-SALT; a finite-element model for aquifers containing a seawater interface
C.I. Voss
1984, Water-Resources Investigations Report 84-4263
Described are modifications to AQUIFEM, a finite element areal ground-water flow model for aquifer evaluation. The modified model, AQUIFEM-SALT, simulates an aquifer containing a freshwater body that freely floats on seawater. Parts of the freshwater lens may be confined above and below by less permeable units. Theory, code modifications, and...
Ground-water-quality monitoring network design for the San Joaquin Valley ground-water basin, California
William E. Templin
1984, Water-Resources Investigations Report 83-4080
Ideal and actual ground-water-quality monitoring networks are proposed for the San Joaquin Valley basin in California. The ideal network, which comprises several subnetworks, provides direction in the development of an actual network of wells currently monitored by known operating agencies. The ideal network can serve as a basis for the...
Appraisal of the surficial aquifers in the Pomme de Terre and Chippewa River Valleys, western Minnesota
W.G. Soukup, D. C. Gillies, C. F. Myette
1984, Water-Resources Investigations Report 84-4086
The surf icial sands in the Pomme de Terre and Chippewa River valleys in Grant, Pope, Stevens, and Swift Counties have been studied to determine the occurrence, availability, and quality of ground water in these aquifers. In the northern part of the Pomme de Terre and Chippewa River valleys, the aquifers...
Sanitary quality of the Jordan River in Salt Lake County, Utah
K. R. Thompson
1984, Water-Resources Investigations Report 83-4252
This investigation of the sanitary quality of the Jordan River was conducted from July 1980 to October 1982 using indicator bacteria rather than specific pathogens. A serious sanitary problem was identified. Concentrations of total coliform bacteria often exceeded 5,000 colonies per 100 milliliters and concentrations of fecal coliform bacteria often...
Water resources of Kosrae, Caroline Islands
Otto Van der Brug
1984, Water-Resources Investigations Report 83-4161
Kosrae is a high volcanic island about 42 square miles in area and the easternmost of the Caroline Islands. Mount Finkol (Mt. Crozer), at 2,065 feet, is the highest point on the island. Mountainous ridges descend sharply to narrow coastal strips which support a population of 5,500 people. Many streams,...
Habitat Suitability Index Models: Rainbow trout
Robert F. Raleigh, Terry Hickman, R. Charles Solomon, Patrick C. Nelson
1984, FWS/OBS 82/10.60
A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for rainbow trout (Salmo gairdneri), a freshwater species. The models are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) to 1 (optimally suitable habitat) for freshwater areas of the continental...
Habitat Suitability Index Models: Great egret
Brian R. Chapman, Rebecca J. Howard
1984, FWS/OBS 82/10.78
The great egret, also called common egret or American egret, is a large white heron tn the order Ciconiiformes, family Ardeidae. Great egrets stand 94.0-104.1 cm (37-41 inches) tall and have a wing spread to 139.7 cm (55 inches) (Terres 1980). The species is associated with streams, ponds, lakes, mud...
Water resources data, Massachusetts and Rhode Island, water year 1982
R. A. Gadoury, G.G. Girouard, D.F. Letty
1984, Water Data Report MA-RI-82-1
Water-resources data for the 1982 water year for Massachusetts and Rhode Island consist of records of stage, discharge, and water quality of streams; contents of lakes and reservoirs; and ground-water levels. This report contains discharge records for 97 gaging stations, monthend contents for 30 lakes and reservoirs, water quality for...
Habitat Suitability Index Models: Pronghorn
Arthur W. Allen, John G. Cook, Michael J. Armbruster
1984, FWS/OBS 82/10.65
This is one of a series of publications that provide information on the habitat requirements of selected fish and wildlife species. Literature describing the relationship between habitat variables related to life requisites and habitat suitability for the pronghorn (Antilocapra americana) are synthesized. These data are subsequently used to develop Habitat Suitability Index (HSI) models. The...
Appraisal of data for ground-water quality in Nebraska
R. A. Engberg
1984, Water Supply Paper 2245
This report summarizes existing data for groundwater quality in Nebraska and indicates their adequacy as a data base. Analyses have been made of water from nearly 10,000 wells by 8 agencies. Those analyses that meet reliability criteria have been aggregated by geologic source of water into four principal aquifer groupings--Holocene-Pleistocene...
