Habitat Suitability Index Models: Gray partridge
Arthur W. Allen
1984, FWS/OBS 82/10.73
This report is part of the Habitat Suitability Index model series which provides habitat information useful for impact assessment and habitat management. The Habitat Use Information section is largely constrained to those data that can be used to derive quantitative relationships between key environmental variables and habitat suitability. The habitat use information provides the...
Evaluation of the efficiency of streamflow data collection strategies for alluvial rivers
P.K. Kitanidis, O. G. Lara, R.W. Lane
1984, Journal of Hydrology (72) 85-103
Streamflow discharge is usually determined indirectly from measurements of the river stage at gaging stations and through the use of stage-discharge relationships (rating curves). However, in alluvial streams, stage-discharge relationships change continually and, sometimes, quite markedly. Such changes may be caused by major floods, seasonal variations, or long-term secular trends...
Distribution and ecology of deep-water benthic foraminifera in the Gulf of Mexico
C. W. Poag
1984, Palaeogeography, Palaeoclimatology, Palaeoecology (48) 25-37
Bathyal and abyssal foraminifera in the Gulf of Mexico are distributed among thirteen generic predominance facies. Five predominance facies nearly encircle the Gulf basin along the slope and rise; a sixth predominance facies blankets the Sigsbee Plain, and a seventh is restricted to the Mississippi Fan. The remaining eight predominance...
Unzipping of the volcano arc, Japan
R. J. Stern, N. C. Smoot, M. Rubin
1984, Tectonophysics (102) 153-174
A working hypothesis for the recent evolution of the southern Volcano Arc, Japan, is presented which calls upon a northward-progressing sundering of the arc in response to a northward-propagating back-arc basin extensional regime. This model appears to explain several localized and recent changes in the tectonic and magrnatic evolution...
Oligocene tectonics and sedimentation, California
Tor H. Nilsen
1984, Sedimentary Geology (38) 305-336
During the Oligocene epoch, California was marked by extensive nonmarine sedimentation, in contrast to its pre-Oligocene and post-Oligocene depositional history. The Oligocene continental deposits are especially widespread in southern California and fill a number of small and generally partly restricted basins. Fluvial facies in many basins prograded over previously deposited...
Crustal structure of the Appalachian Highlands in Tennessee
C. Prodehl, J. Schlittenhardt, S.W. Stewart
1984, Tectonophysics (109) 61-76
Crustal structure of the southern Appalachians and adjacent Interior Low Plateaus in Tennessee is derived from seismic-refraction measurements observed by the U.S. Geological Survey in 1965 along reversed lines, normal (NW-SE) and parallel (NE-SW) to the structure of the Appalachian Highlands' major geologic divisions. Its easternmost part is located approximately...
A review of crust and upper mantle structure studies of the Snake River Plain-Yellowstone volcanic system: A major lithospheric anomaly in the western U.S.A.
H. M. Iyer
1984, Tectonophysics (105) 291-308
The Snake River Plain-Yellowstone volcanic system is one of the largest, basaltic, volcanic field in the world. Here, there is clear evidence for northeasterly progression of rhyolitic volcanism with its present position in Yellowstone. Many theories have been advanced for the origin of the Snake River Plain-Yellowstone system. Yellowstone and...
Transport and concentration controls for chloride, strontium, potassium and lead in Uvas Creek, a small cobble-bed stream in Santa Clara County, California, U.S.A.: 1. Conceptual model
V. C. Kennedy, A. P. Jackman, S.M. Zand, G. W. Zellweger, R.J. Avanzino
1984, Journal of Hydrology (75) 67-110
Stream sediments adsorb certain solutes from streams, thereby significantly changing the solute composition; but little is known about the details and rates of these adsorptive processes. To investigate such processes, a 24-hr. injection of a solution containing chloride, strontium, potassium, sodium and lead was made at the head of a...

1984, Journal of Hydrology (75) 167-194
The Hyde Park landfill is a 15-acre (6.1 ha) chemical waste disposal site located north of Niagara Falls, New York. Underlying the site in descending order are: (1) low-permeability glacial till and lacustrine deposits; (2) a moderately permeable fractured rock aquifer - the Lockport Dolomite; and (3) a low-permeability unit...
Transport and concentration controls for chloride, strontium, potassium and lead in Uvas Creek, a small cobble-bed stream in Santa Clara County, California, U.S.A.: 2. Mathematical modeling
A. P. Jackman, R. A. Walters, V. C. Kennedy
1984, Journal of Hydrology (75) 111-141
Three models describing solute transport of conservative ion species and another describing transport of species which adsorb linearly and reversibly on bed sediments are developed and tested. The conservative models are based on three different conceptual models of the transient storage of solute in the bed. One model assumes the...
Groundwater-flow parameter estimation and quality modeling of the Equus Beds aquifer in Kansas, U.S.A.
M.A. Sophocleous
1984, Journal of Hydrology (69) 197-222
The salinity problems created in the Burrton area as a result of poor oil-field brine disposal practices of the past continue to be a major concern to the area depending on the Equus Beds aquifer for water, including the City of Wichita, Kansas. In this paper, an attempt is made...
Experimental studies in natural groundwater recharge dynamics: Assessment of recent advances in instrumentation
M. Sophocleous, C. A. Perry
1984, Journal of Hydrology (70) 369-382
To quantify and model the natural groundwater-recharge process, two sites in south-central Kansas, U.S.A., were instrumented with various modern sensors and data microloggers. The atmospheric-boundary layer and the unsaturated and saturated soil zones were monitored as a unified regime. Data from the various sensors were collected using microloggers in combination...

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.

Evaluation of future base-flow water-quality conditions in the Hillsborough River, Florida
Mario Fernandez Jr., C. L. Goetz, J.E. Miller
1984, Water-Resources Investigations Report 83-4182
A one-dimensional, steady-state, water-quality model was developed for a 30.0 mile reach of the Hillsborough River to evaluate water-quality conditions to be expected from future development. The model was calibrated and verified using data collected under critical base-flow conditions in April and December 1978. Dissolved organic nitrogen, nitrate nitrogen, and...
Water-quality assessment of the Illinois River basin, Arkansas
J. E. Terry, E. E. Morris, Jim C. Petersen, M.E. Darling
1984, Water-Resources Investigations Report 83-4092
A water-quality assessment was made of Illinois River, Muddy Fork, Spring Creek, and Osage Creek in northwest Arkansas. Data were collected to calibrate and verify steady-state digital, stream, water-quality models. The models were then used to simulate changes in instream diel-minimum dissolved-oxygen resulting from changes in nutrient loading. The city...
Runoff, sediment transport, and water quality in a northern Illinois agricultural watershed before urban development, 1979-81
H.E. Allen Jr., J. R. Gray
1984, Water-Resources Investigations Report 82-4073
A study designed to quantify and evaluate changes in runoff and sediment transport attributable to construction activities during urban development of a watershed required identification of pre-construction hydrologic conditions. Data collected before construction on a 2.81 sq m (7.28 sq km) agricultural watershed (upper Spring Creek) near Rockford, IL, show...
Floods of March 1982, Indiana, Michigan, and Ohio
D.R. Glatfelter, G.K. Butch, J. A. Stewart
1984, Water-Resources Investigations Report 83-4201
Rapid melting of a snowpack containing 2 to 6 inches of water equivalent coinciding with moderate rainfall caused flooding in March 1982 across northern Indiana, southern Michigan, and northwestern Ohio. Millions of dollars in property damage and the loss of four lives resulted from the flooding. Peak discharges at several...

S. G. Robson
1984, Open-File Report 84-431
The Denver metropolitan area is experiencing a rapid population growth that is requiring increasing supplies of potable water to be pumped from bedrock aquifers in order to meet demand. In an effort to determine the ability of the aquifers to continue to meet this demand, the Colorado Department of Natural...
