Use and interpretation of strong-motion records from highway bridges
J.D. Raggett, Christopher Rojahn
1978, Open-File Report 78-707
This report describes how strong-motion records obtained from the earthquake-induced motions of highway bridges may be analyzed for use in the evaluation of bridge designs and bridge design procedures.This report is divided into five principal sections. The first section describes strong-motion instrumentation and strong-motion records. In the second section, a...
Monitoring water-quality during pilot-dredging operations in the Willamette and Columbia Rivers, Oregon
Joseph F. Rinella, Stuart W. McKenzie
1978, Open-File Report 78-554
Water quality was monitored in the Willamette and Columbia Rivers during a pilot dredging operation on December 16, 1977. Monitoring included in-situ measurements of pH, temperature, dissolved oxygen, and conductivity in the Willamette and Columbia Rivers; analyses of dissolved ammonia, dissolved manganese, suspended-sediment concentration and particle size, loss on ignition,...
Water quality in the Old Plantation Water Control District, Broward County, Florida; progress report, July 1976-June 1977
Gary M. Russell, Chris E. Hanson, William A.J. Pitt
1978, Open-File Report 78-411
Water quality in the Old Plantation Water Control District in Broward County, Florida has been affected by effluent from sewage-treatment plants, agriculture, and storm-water runoff. Effect of the effluent from sewage-treatment plants on water quality was evident at 3 sites where concentrations of nutrients and bacteria in the Broward County...
Preliminary sulfur isotope investigations of mineral deposits in the Precambrian shield, Kingdom of Saudi Arabia
Ralph Jackson Roberts, Robert O. Rye, Mustafa M. Mawad
1978, Open-File Report 78-776
Massive sulfide deposits and sulfide-bearing veins in Saudi Arabia show a wide range in δ34S values from very negative to strongly positive and cover almost the entire range observed for ore deposits in nature.Massive sulfide deposits that have very negative values (Wadi Wassat and Wadi Qatan) formed as syngenetic sedimentary...
Fluvial sediment study of Fishtrap and Dewey Lakes drainage basins, Kentucky-Virginia
William F. Curtis, Russell F. Flint, Frederick H. George, John F. Santos
1978, Water-Resources Investigations Report 77-123
Fourteen drainage basins above Fishtrap and Dewey Lakes in the Levisa Fork and Johns Creek drainage basins of eastern Kentucky and southwestern Virginia were studied to determine sedimentation rates and origin of sediment entering the two lakes. The basins ranged in size from 1.68 to 297 square miles. Sediment yields...
A 500-volt pulse transmitter for ice sounding
Charles J. Roubique
1978, Open-File Report 78-372
A high-voltage pulser developed by the U.S. Geological Survey for glacier soundings is a small battery-operated unit that weighs about one kg and was packaged in a case measuring 8.2 X 12 X 18.8 cm. It operates from an external 12 volt battery and supplies a 500-V pulse to a...
Report on the beach dynamics, geology, and oil spill susceptibility of the Gulf of Alaska coastline in Glacier Bay National Monument -- Sea Otter Creek to Icy Point
Bruce Molnia, Mark C. Wheeler
1978, Open-File Report 78-284
Observations of the Gulf of Alaska coastline in Glacier Bay National Monument were conducted between June 1975 and July 1977 to: (1) characterize the beach environment, and (2) assess the effects of an oil spill (fig. 1). These included overflights in June 1975, June 1976, July 1976, January 1977, May...
Ground water withdrawn for municipal, industrial, and irrigation use in the Upper Peace and Alafia River basins, west-central Florida, 1970-74
Alton F. Robertson, L. R. Mills, D.C. Parsons
1978, Open-File Report 78-29
Data are presented for ground-water withdrawals for municipal, industrial and irrigation use in the upper Peace and Alafia River basins during 1970-71. Within the 1,160-square-mile study area, the principal source of ground water is the Floridan aquifer. Methods used to determine ground-water withdrawal include: metering water use; relating measured well...
Geologic setting of the lead and zinc deposits, Drenchwater Creek area, Howard Pass Quadrangle, Western Brooks Range, Alaska
Warren J. Nokleberg, Gary R. Winkler
1978, Open-File Report 78-70-C
Significant concentrations of galena, sphalerite, and minor barite are present in the Drenchwater Creek area, Howard Pass quadrangle, western Brooks Range, Alaska. Detailed geologic mapping indicates that galena, sphalerite and pyrite occur sporadically in a zone at least 1,830 m. long and 6-30 m. wide. The sulfides occur in tuff,...
Stamukhi shoals of the Arctic - some observations from the Beaufort Sea
Erk Reimnitz, Douglas K. Maurer
1978, Open-File Report 78-666
A number of linear shoals, representing pronounced topographic anomalies on the surface of the Arctic shelf, have been studied in the Prudhoe Bay area. These shoals have been referred to in several previous studies. Based on seismic reflection records, Reimnitz et al., (1972a), stated that the shoals are constructional features...
Impact of coastal processes on resource development with an example from Icy Bay, Alaska
Bruce F. Molnia
1978, Open-File Report 79-1693
The coastline of Alaska is dynamic and continually readjusting to changes in the many processes that operate in the coastal zone. Because of this dynamic nature, special consideration must be made in planning for development, and. caution must be exercised in site selection for facilities to be emplaced in the...
Geologic map of the Boulder-Fort Collins-Greeley area, Colorado
Roger B. Colton
1978, IMAP 855-G
This digital map shows the geographic extent of rock stratigraphic units (formations) as compiled by Colton in 1976 under the Front Range Urban Corridor Geology Program. Colton used his own geologic mapping and previously published geologic maps to compile one map having a single classification of geologic units....
