Small-stream flood investigations in Minnesota, October 1958 to September 1977
George H. Carlson, Kurt T. Gunard
1979, Open-File Report 79-1061
An investigation of flood flows from small drainage basins in Minnesota is being made to aid in the design of bridges, culverts and other highway drainage structures. Results of the investigation provide peak-flow data on streams generally with drainage areas less than 50 square miles, placing particular emphasis on those...
Maps showing ground-water conditions in the New Driver-Cave Creek area, Maricopa and Yavapai counties, Arizona; 1977
G. R. Littin
1979, Water-Resources Investigations Report 79-1068
The New River-Cave Creek area includes about 500 square miles in central Arizona. The ground-water conditions vary greatly owing to large differences in rock type and extent of fracturing. Information shown on the maps includes depth to water, altitude of the water level, well depth, and specific conductance and fluoride...
Tertiary volcanic rocks of the Mineral Mountain and Teapot Mountain quadrangles, Pinal County, Arizona
William J. Keith, Ted G. Theodore
1979, Open-File Report 79-716
The widespread distribution of Tertiary volcanic rocks in south-central Arizona is controlled in part by prevolcanic structures along which volcanic vents were localized. Volcanic rocks in the Mineral Mountain and Teapot Mountain quadrangles mark the site of a major northwest-trending structural hingeline. This hingeline divides an older Precambrian X terrane...
Radiocarbon dates from the Hawaiian Islands: A compilation
M. Lea Kelley
1979, Open-File Report 79-1700
Radiocarbon dating has proved to be a useful tool for the correlation of events and their timing during the Quaternary. In the Hawaiian Islands, the application of this technique is providing a chronology of the geologic history that will serve as a framework for studies of volcanologic and related hazards,...
Programs EMCUPL and SCHCOPL: computation of electromagnetic coupling on a layered halfspace with complex conductivities
James P. Kauahikaua, Walter L. Anderson
1979, Open-File Report 79-1430
A number of efficient numerical computer algorithms are incorporated into a general program called EMCUPL, which calculates the electromagnetic (EM) coupling between two straight wires on the surface of a multilayered half space. Each layer has an isotropic conductivity which may be either real or complex. A second computer program,...
Marine seismic sonobuoy data from the Bering Sea region
Jonathan R. Childs, Alan K. Cooper
1979, Open-File Report 79-371
Throughout the field seasons of 1975 to 1978, the Geological Survey carried out an extensive program of seismic sonobuoy research aboard the R/V S.P. LEE over the entire Bering Sea region. 75 successful sonobuoy refraction and wide angle reflection stations were recorded over the shelf areas of Navarin Basin, St....
A methodology for post-EIS (environmental impact statement) monitoring
Linda Graves Marcus
1979, Circular 782
A methodology for monitoring the impacts predicted in environmental impact statements (EIS's) was developed using the EIS on phosphate development in southeastern Idaho as a case study. A monitoring system based on this methodology: (1) coordinates a comprehensive, intergovernmental monitoring effort; (2) documents the major impacts that result, thereby improving...
