Ground-water-level trends in Idaho, 1971-82
H.W. Young, R.F. Norvitch
1984, Water-Resources Investigations Report 83-4245
Water-level trends, net water-level changes, and major causes governing these water-level fluctuations are presented for 366 wells in the Idaho statewide observation-well network. Water-level trends were determined for 293 wells. Downward trends in 176 of these wells ranged from less than 1 foot per year to a maximum of 7...
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...
Geologic map of southeastern Alaska
George E. Gehrels, Henry C. Berg
1984, Open-File Report 84-886
Southeastern Alaska is underlain by sedimentary, volcanic, intrusive, and metamorphic rocks of Quaternary to Cambrian, and probable Proterozoic age. These rocks have been classified on the geologic map and in this pamphlet into units that emphasize the regional distribution of lithically similar and generally coeval geologic units. The distribution, age,...
Habitat Suitability Index Models and Instream Flow Suitability Curves: White bass
Karen Hamilton, Patrick C. Nelson
1984, FWS/OBS 82/10.89
Habitat characteristics important to white bass (Morone chrysops) are reviewed in this report using two techniques developed by the U.S. Fish and Wildlife Service, the Habitat Evaluation Procedures (HEP) and the Instream Flow Incremental Methodology (IFIM). The Suitability Index (SI) curves and graphs and Habitat Suitability Index (HSI) models developed...
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...
Development of a model to predict the adsorption of lead from solution on a natural streambed sediment
David Wayne Brown, John David Hem
1984, Water Supply Paper 2187
Adsorption of solutes by solid mineral surfaces commonly influences the dissolved ionic composition of natural waters. A model based on electrical double-layer theory has been developed which appears to be capable of characterizing the surface chemical behavior of a natural fine-grained sediment containing mostly quartz and feldspar. This variable surface...
Preliminary assessment of climatic change during Late Wisconsin time, southern Great Basin and vicinity, Arizona, California, and Nevada
W. G. Spaulding, S.W. Robinson, Frederick L. Paillet
1984, Water-Resources Investigations Report 84-4328
Nine plant macrofossil assemblages from the Eleana Range-2 packrat (Neotoma sp.) midden span 6,500 radiocarbon years and record local vegetational changes in the southern Great Basin of Nevada during the last one-half of the Late Wisconsin glacial age. Climatic reconstructions were developed to account for these changes. During the late...
Ground-water contamination by crude oil at the Bemidji, Minnesota, research site; US Geological Survey Toxic Waste--ground-water contamination study
M. F. Hult, editor(s)
1984, Water-Resources Investigations Report 84-4188
The U.S. Geological Survey has begun a research project to improve understanding of the mobilization, transport, and fate of petroleum contaminants in the shallow subsurface and to use this understanding to develop predictive models of contaminant behavior. The project site is near Bemidji in northern Minnesota where an accidental spill of...
