Radioactive mineral spring precipitates, their analytical and statistical data and the uranium connection
R. A. Cadigan, J.K. Felmlee
1982, Open-File Report 82-743
Major radioactive mineral springs are probably related to deep zones of active metamorphism in areas of orogenic tectonism. The most common precipitate is travertine, a chemically precipitated rock composed chiefly of calcium carbonate, but also containing other minerals. The mineral springs are surface manifestations of hydrothermal conduit systems which extend...
Water-quality characteristics of streams in forested and rural areas of North Carolina
Clyde E. Simmons, Ralph C. Heath
1982, Water Supply Paper 2185-B
Data collected in North Carolina during 1973-78 from a statewide network of 39 rural sampling sites were used to define unpolluted or baseline stream quality. The basins were 90 to 100 percent forested and, except for the unknown effects of air pollution, were relatively unaffected by man 's activities. Five...
Estimating peak flow characteristics at ungaged sites by ridge regression
Gary D. Tasker
1982, Open-File Report 82-333
A regression simulation model, is combined with a multisite streamflow generator to simulate a regional regression of 50-year peak discharge against a set of basin characteristics. Monte Carlo experiments are used to compare the unbiased ordinary lease squares parameter estimator with Hoerl and Kennard's (1970a) ridge estimator in which the...
Water quality of the Barataria Unit; Jean Lafitte National Historical Park, Louisiana
Charles R. Garrison
1982, Open-File Report 82-691
Surface-water samples were collected on a monthly basis for the period April 1981-March 1982 from six sites within the Barataria Marsh Unit of the Jean Lafitte National Historic Park, Louisiana. The sites were located on Bayou Segnette, Kenta Canal , and Millaudon Canal. Biological, chemical, and physical analyses were performed....
U.S. Geological Survey research in radioactive waste disposal - Fiscal year 1979
Robert Schneider, E.H. Roseboom, J.B. Robertson, P. R. Stevens
1982, Circular 847
The report summarizes progress on geologic and hydrologic research related to the disposal of radioactive wastes. The research is described according to whether it is related most directly to: (1) high-level and transuranic wastes; (2) low-level wastes, or (3) uranium mill tailings. Included is research applicable to the identification and...
Electrical studies at the proposed Wahmonie and Calico Hills nuclear waste sites, Nevada Test Site, Nye County, Nevada
D.B. Hoover, Michael P. Chornack, K.H. Nervick, M. M. Broker
1982, Open-File Report 82-466
Two sites in the southwest quadrant of the Nevada Test Site (NTS) were investigated as potential repositories for high-level nuclear waste. These are designated the Wahmonie and Calico Hills sites. The emplacement medium at both sites was to be an inferred intrusive body at shallow depth; the inference of the...
A recommended procedure for the preparation of oriented clay-mineral specimens for X-ray diffraction analysis; modifications to Drever's filter-membrane peel technique
R. M. Pollastro
1982, Open-File Report 82-71
Extremely well-oriented clay mineral mounts for X-ray diffraction analysis can be prepared quickly and without introducing segregation using the filter-membrane peel technique. Mounting problems encountered with smectite-rich samples can be resolved by using minimal sample and partial air-drying of the clay film before transfer to a glass slide. Samples containing...
A Numerical model to evaluate proposed ground-water allocations in southwest Kansas
D. G. Jorgensen, H. F. Grubb, C.H. Baker, G.E. Hilmes, E. D. Jenkins
1982, Water-Resources Investigations Report 82-4095
A computer model was developed to assist the Southwest Kansas Groundwater Management District No. 3 in the evaluation of applications to appropriate ground water. The model calculated the drawdown due from a proposed well at all existing wells in the section of the proposed well and at all wells in...
Habitat Suitability Index Models: Brook trout
Robert F. Raleigh
1982, FWS/OBS 82/10.24
The habitat use information and Habitat Suitability Index (HSI) models presented in this document are an aid for impact assessment and habitat management activities. Literature concerning a species' habitat requirements and preferences is reviewed and then synthesized into HSI models, which are scaled to produce an index between 0 (unsuitable...
Habitat suitability index models: Coastal stocks of striped bass
Mark B. Bain, Jane L. Bain
1982, FWS/OBS 82/10.1
A review and synthesis of existing information were used to develop estuarine habitat models for coastal stocks of striped bass (Morone saxatilis). Models for five life stages are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) and 1 (optimally suitable habitat) for estuarine areas of the...
