Henry L. Short, Robert J. Cooper
1985, FWS/OBS 82/10.99
The great blue heron is the largest, most widely distributed, and best known of the American herons (Henny 1972). Great blue herons occur in a variety of habitats from freshwater lakes and rivers to brackish marshes, lagoons, mangrove areas, and coastal wetlands (Spendelow and Patton in prep.)....
Habitat Suitability Index Models: Lesser snow goose (wintering)
John C. Leslie, Phillip J. Zwank
1985, FWS/OBS 82/10.97
The lesser snow goose may have the largest population of any goose in the world (Cooch 1958; Kerbes 1975; Ogilvie 1978). Its arctic breeding range has greatly expanded since the mid-1950's (Bellrose 1976). In the United States, it normally ranks behind only the Canada goose (Branta canadensis) in population size...

Habitat Suitability Index Models: Southern and gulf flounders
Kevin M. Enge, Rosemarie Mulholland
1985, FWS/OBS 82/10.92
Both the southern and gulf flounders (paralichthrS lethostigma, f. albi~utta) are important commercial and recreationa species. Catch statlstics for flounder do not differentiate between species; however, southern flounders are more common than gulf flounders except on the gulf coast of Florida (Topp and Hoff 1972). The commercial fishery consists of...

A kinematic model for the structure of lee-side (dune-like) deposits
Ralph E. Hunter
1985, Sedimentology (32) 409-422
A kinematic model for the structure of the lee-side deposit of a dune-like bedform, Gilbert-type delta, or similar step is developed, based on the assumptions that initial deposition is entirely by grainfall, that the rate of deposition decreases as a power function of distance downflow from the brink of the...
Accretion tectonics and crustal structure in Alaska
P.J. Coney, D. L. Jones
1985, Tectonophysics (119) 265-283
The entire width of the North American Cordillera in Alaska is made up of "suspect terranes". Pre-Late Cretaceous paleogeography is poorly constrained and the ultimate origins of the many fragments which make up the state are unclear. The Prince William and Chugach terranes accreted since Late Cretaceous time and represent...

1985, Precambrian Research (30) 27-41
Samples of 20 chromitite, 14 ultramafic and mafic rock, and 9 laterite and soil samples from the Precambrian Sukinda and Nausahi ultramafic complexes, Orissa, India were analyzed for platinum-group elements (PGE). The maximum concentrations are: palladium, 13 parts per billion (ppb); platinum, 120 ppb; rhodium, 21 ppb; iridium, 210 ppb;...
Hydraulic gradient control for groundwater contaminant removal
Atwood D. Fisher, S.M. Gorelick
1985, Journal of Hydrology (76) 85-106
The Rocky Mountain Arsenal near Denver, Colorado, U.S.A., is used as a realistic setting for a hypothetical test of a procedure that plans the hydraulic stabilization and removal of a groundwater contaminant plume. A two-stage planning procedure successfully selects the best wells and their optimal pumping/recharge schedules to contain the...
Evaluating the hydraulic effects of changes in aquifer elevation using curvilinear coordinates
E. Weiss
1985, Journal of Hydrology (81) 253-275
The groundwater flow equation is written in curvilinear coordinates whose coordinate surfaces coincide with the top and bottom surfaces of folded layers of aquifers. The coordinates are general enough for these surfaces to coincide for almost all groundwater systems. The terms of the finite-difference approximation for the flow equation can...

Quaternary sedimentation of the Alaskan Beaufort shelf: Influence of regional tectonics, fluctuating sea levels, and glacial sediment sources
David A. Dinter
1985, Tectonophysics (114) 133-161
The offshore stratigraphy of the Quaternary Gubik Formation of Arctic Alaska has been studied on high-resolution seismic profiles with a maximum sub-seafloor penetration of about 100 m. In general, marine transgressive subunits of the Gubik Formation are wedge-shaped on the shelf, thickening slightly seaward to the shelf break, beyond which...

The alluvial aquifer occurs in the South Fork Solomon River valley between Webster Reservoir and Waconda Lake...
Water quality and streamflow data for the West Fork Trinity River in Fort Worth, Texas
S. C. McCutcheon
1985, Water-Resources Investigations Report 84-4330
Water-quality data were collected on a 13.6-mile reach of the West Fork Trinity River in Fort Worth, Texas to test a dynamic Lagrangian model. Flow was steady. Loads of dissolved constituents varied with time at the beginning of the study reach and in the reach, primarily because of photosynthesis. River...
Evaluation of major dike-impounded ground-water reservoirs, Island of Oahu
Kiyoshi J. Takasaki, John Francis Mink
1985, Water Supply Paper 2217
Ground-water reservoirs impounded by volcanic dikes receive a substantial part of the total recharge to ground water on the island of Oahu because they generally underlie the rainiest areas. These reservoirs accumulate the infiltration from rainfall, store it temporarily, and steadily leak it to abutting basal reservoirs or to streams...

The quality of water in the principal aquifers of southwestern Washington
J.C. Ebbert, K. L. Payne
1985, Water-Resources Investigations Report 84-4093
The quality of water in major aquifers in southwestern Washington was addressed in terms of inorganic-constituent, trace-metal, and fecal-coliform concentrations. Results of this assessment indicate that the groundwater in southwestern Washington can be characterized as soft to moderately hard with a low concentration of dissolved solids. Nitrate was the only...

Evaluation of the ground-water resources of the lower Susquehanna River basin, Pennsylvania and Maryland
James M. Gerhart, George J. Lazorchick
1985, Open-File Report 84-748
Ground water in the 3,458-square-mile lower Susquehanna River basin occupies secondary openings in bedrock. The distribution of openings is a function of lithology, depth, and topography. Local flow systems account for most of the total ground-water flow. Average annual recharge for the lower basin is 1,857 million gallons per day,...
