Urban storm-runoff modelling; Madison, Wisconsin
R. Stephen Grant, Gerald Goddard
1979, Open-File Report 79-1273
The Illinois Urban Drainage Area Simulator was used to analyze the effects that (1) physical changes to storm-sewer conduits, and (2) increased runoff detention and infiltration would have on storm runoff in four urban basins in Madison, Wisconsin. The model was calibrated using monitoring data for the four basins collected...
Enhancement of Landsat images for lineament analysis in the area of the Salina Basin, New York and Pennsylvania
M. Dennis Krohn
1979, Open-File Report 79-533
Digital image processing of Landsat images of New York and Pennsylvania was undertaken to provide optimum images for lineament analysis in the area of the Salina Basin. Preliminary examination of Landsat images from photographic prints indicated sufficient differences between the spectral bands of the Landsat Multispectral Scanner (MSS) to warrant...
Seismic, magnetic, and geotechnical properties of a landslide and clinker deposits, Powder River basin, Wyoming and Montana
C.H. Miller
1979, Open-File Report 79-952
Exploitation of vast coal and other resources in the Powder River Basin has caused recent, rapid increases in population and in commercial and residential development and has prompted land utilization studies. Two aspects of land utilization were studied for this report: (1) the seismic and geotechnical properties of a landslide...
Summary of references to mineral occurrences (other than mineral fuels and construction materials) in the Kenai and Tyonek quadrangles, Alaska
Edward Huntington Cobb
1979, Open-File Report 80-86
This summary of references is designed to aid in library research on metallic and nonmetallic (other than mineral fuels and construction materials) mineral deposits in the Kenai and Tyonek quadrangles, Alaska. References to most reports of the Geological Survey, U.S. Bureau of Mines, and State of Alaska Division of Geological...
Summary of references to mineral occurrences (other than mineral fuels and construction materials) in the Cordova Quadrangle, Alaska
Edward Huntington Cobb
1979, Open-File Report 79-973
This summary of references is designed to aid in library research on metallic and nonmetallic (other than mineral fuels and construction materials) mineral occurrences in the Cordova quadrangle, Alaska. References to most reports of the Geological Survey, U. S. Bureau of Mines, and State of Alaska Division of Geological and...
Availability of single channel seismic refraction profiles collected over U.S. Atlantic continental slope and rise north of Cape Hatteras - USGS cruises FAY 20 and FAY 21 - August/September 1976
Kim D. Klitgord
1979, Open-File Report 79-578
A series of single channel seismic reflection profiles were collected by the U.S. Geological Survey aboard the R.V. FAY from August 10, 1976 through September 7, 1976 during cruises FAY 20 and FAY 21. The chief scientist was, Dr. Kim D. Klitgord, U.S. Geological Survey, Woods Hole, MA 02543. The...
Progress in remote sensing as it applies to missions of Committee for Coordination of Joint Prospecting for Mineral Resources in Asian Offshore Areas
William A. Fischer
1979, Open-File Report 79-598
The major thrusts of investigations of the use of space data for understanding our Earth continue to focus on the land and near-shore environments. This is expectable; people live on the land, draw most of their resources from the land or near-shore areas, and in these areas environmental degradation or...
In situ bulk density and porosity estimates from borehole gravity data in limestones of the Madison Group; test well No. 1, Crook County, Wyoming
Bruce A. Kososki, Stephen L. Robbins
1979, Open-File Report 79-1514
In 1975 the U.S. Geological Survey, in cooperation with the Old West Regional Commission, prepared a plan of study (U.S. Geological Survey, 1975) for evaluating the water-supply potential of limestone of the Madison Group and associated rocks. To obtain better subsurface hydrologic and geologic information it was recognized that Madison...
Geology and porphyry copper-type alteration-mineralization of igneous rocks at the Christmas Mine, Gila County, Arizona
Randolph A. Koski
1979, Open-File Report 79-844
The Christmas copper deposit, located in southern Gila County, Arizona, is part of the major porphyry copper province of southwestern North America. Although Christmas is known for skarn deposits in Paleozoic carbonate rocks, ore-grade porphyry-type copper mineralization also occurs in a composite granodioritic intrusive complex and adjacent mafic volcanic country...
Downhole pumps for water sampling in small diameter wells
F. C. Koopman
1979, Open-File Report 79-1264
The relatively high cost and difficulty in locating a source of pumps for use in obtaining ground-water samples from small-diameter wells has demonstrated a need for this report. Criteria for selection of a pump and pumping equipment to meet specific requirements has been tabulated to assist field personnel in making...
The concentration and mobility of elements in subalpine forest soils in Colorado and Idaho
Gary C. Curtin, Harley D. King, J. M. Nishi
1979, Open-File Report 79-710
Leaching studies of subalpine forest soils collected at seven sites in Colorado and Idaho show that copper, cobalt, chromium, magnesium, barium, tin, strontium, and yttrium are highly mobile elements in these soils; that zirconium, lanthanum, nickel, and scandium are moderately mobile; and that titanium is rather immobile. Furthermore, the results...
