Storage analyses for ephemeral streams in semiarid regions
K. C. Glover
1984, Water-Resources Investigations Report 83-4078
A model has been developed for determining the probability of a reservoir being unable to provide a specified downstream water supply. By applying the model with a number of assumed storage capacities, the long-term water supply potential of a stream below a reservoir can be evaluated. Previous methods for determining...
Low-flow transport models for conservative and sorbed solutes — Uvas Creek, near Morgan Hill, California
A. P. Jackman, R. A. Walters, V. C. Kennedy
1984, Water-Resources Investigations Report 84-4041
Models describing low-flow transport of conservative (nonreactive) and reactive solutes, which adsorb on the streambed, are developed and tested. Temporary storage within the bed plays an important role in solute movement. Three different models of bed-storage processes are developed for conservative solutes. One model assumes the bed is a well-mixed,...
Hydrologic conditions in the Chicod Creek basin, North Carolina, before and during channel modifications, 1975-81
S.A. Watkins, C.E. Simmons
1984, Water-Resources Investigations Report 84-4025
Beginning in late 1978, stream channels throughout the 60-square mile Chicod Creek basin underwent extensive modification to increase drainage efficiency and reduce flooding potential. Drainage modifications in this Coastal Plain basin, consisting primarily of channel excavation and clearing of channel blockages, were completed in December 1981. The hydrologic condition of...
Basic concepts of kinematic-wave models
J.E. Miller
1984, Professional Paper 1302
The kinematic-wave model is one of a number of approximations of the dynamic-wave model. The dynamic-wave model describes onedimensional shallow-water waves (unsteady, gradually varied, openchannel flow). This report provides a basic reference on the theory and applications of the kinematic-wave model and describes the limitations of the model in relation...
Flood-discharge profiles of selected streams in Rockland County, New York
Richard Lumia
1984, Water-Resources Investigations Report 84-4049
Flood-discharge profiles of 10 streams in Rockland County at six recurrence intervals ranging from 2 to 100 years are presented. Synthetic flood-frequency estimates were derived for nine rainfall-runoff sites from calibrated models; observed flood-frequency estimates were derived for three sites having long-term discharge records. A variance-weighting technique was applied to...
Glastonbury Gneiss and mantling rocks (a modified Oliverian dome) in south-central Massachusetts and north-central Connecticut: Geochemistry, petrogenesis, and isotopic age
G. W. Leo, R. E. Zartman, D. G. Brookins
1984, Professional Paper 1295
The Glastonbury dome is a long, narrow structure trending approximately 70 km north-northeast through Connecticut and Massachusetts along the west side of the Bronson Hill anticlinorium. Structurally and stratigraphically the dome is analogous to the Oliverian domes of New Hampshire. It is cored by Glastonbury Gneiss and is mantled by...
Synthesized flood frequency for small urban streams in Tennessee
C. H. Robbins
1984, Water-Resources Investigations Report 84-4182
Bridge, culvert, and highway design often require knowledge of the magnitude and frequency of flood discharge from small streams where the drainage basin is urbanized. The results of a 6-year study by the U.S. Geological Survey provide methods for estimating flood magnitudes for selected frequencies on small streams draining urban...
Habitat Suitability Index Models: Pink shrimp
Rosemarie Mulholland
1984, FWS/OBS 82/10.76
Shrimp support the most valuable seafood industry in the United States (Roedel 1973; National Marine Fisheries Service 1983). The three most important commercial species are the white shrimp (Penaeus setiferus L.), brown shrimp (P. aztecus Ives), and pink shrimp (P. duorarum Burkenroad). Adult pink shdmp are caught "in commercial quantities...
Habitat Suitability Index Models and Instream Flow Suitability Curves: Redear sunfish
Kathleen A. Twomey, Glen Gebhart, O. Eugene Maughan, Patrick C. Nelson
1984, FWS/OBS 82/10.79
The redear sunfish (Lepomis microlophus), commonly referred to as the shellcracker, is native from the Mississippi River in Missouri and southern Indiana to North Carolina, south through Florida, and west to eastern Texas (Cole 1951; Trautman 1957; Hubbs and Lagler 1964; Wilbur 1969; Pflieger 1975). The species has been successfully...
Habitat Suitability Index Models and Instream Flow Suitability Curves: Paddlefish
Wayne A. Hubert, Stanley H. Anderson, Peter D. Southall, Johnie H. Crance
1984, FWS/OBS 82/10.80
The original range of the paddlefish was the Mississippi River drainage and adjacent Gul f Coast dra i nage. It was once found in some of the Great Lakes (Carlson and Bonislawsky 1981). The paddlefish is generally an inhabitant of large rivers, but it occurs in reservoirs and natural lakes...
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...
Habitat Suitability Index Models: Canvasback (breeding habitat)
Richard L. Schroeder
1984, FWS/OBS 82/10.82
Canvasbacks (Aythya valisineria) breed from Alaska south to Montana and the Dakotas, with the highest breeding densities found in the parklands of Southcentral Canada (Bellrose 1976). Canvasbacks nest over water in a variety of wetland habitats, including large marshes, ponds, sloughs, and potholes. Their preferred breeding habitat is shallow prairie...
Habitat Suitability Index Models: Lake trout (exclusive of the Great Lakes)
Michael D. Marcus, Wayne A. Hubert, Stanley H. Anderson
1984, FWS/OBS 82/10.84
The lake trout is an important commercial and sport fish in North America. In the Central Rocky Mountain regi on, 1ake trout are common ly referred to as "mackinaw". There is good evidence that lake trout should be called "1 ake charr" (Morton 1980). No subspecies of lake trout is...
Habitat Suitability Index Models: The Arizona guild and layers of habitat models
Henry L. Short
1984, FWS/OBS 82/10.70
This document is part of the Habitat Suitability Index Models Series, which provides habitat information useful for impact assessment and habitat management. Both of the models described in this report are based on the significant association of Wildlife species with vegetation structure. The models compare the structure in the study...

Paul T. Kostecki
1984, FWS/OBS 82/10.75
The estuarine spotted seatrout, a primarily estuarine species, is one of the most important sport and commercial fishes in coastal Gulf of Mexico waters (Arnold et a1. 1976). Spotted seatrout rank second by weight in catches by U.S. saltwater sport fishermen (National Marine Fisheries Services 1981) ....
Techniques for estimating magnitude and frequency of floods on streams in Indiana
D.R. Glatfelter
1984, Water-Resources Investigations Report 84-4134
Equations are presented for estimating the magnitude and frequency of floods at ungaged sites on unregulated and nonurban streams in Indiana. The equations were developed by multiple-regression, analysis of basin characteristics and peak-flow statistical data from 242 gaged locations in Indiana, Ohio, and Illinois. The State of Indiana was divided...

Ground-water models as a management tool in Florida
C. B. Hutchinson
1984, Water-Resources Investigations Report 84-4016
Highly sophisticated computer models provide powerful tools for analyzing historic data and for simulating future water levels, water movement, and water chemistry under stressed conditions throughout the ground-water system in Florida. Models that simulate the movement of heat and subsidence of land in response to aquifer pumping also have potential...
