Simulation of dissolved oxygen and biochemical oxygen demand, Plantation Canal, Broward County, Florida with an evaluation of the QUAL-I model for use in south Florida
Thomas N. Russo, Raul S. McQuivey
1975, Water-Resources Investigations Report 75-59
A mathematical model; QUAL-I, developed by the Texas Water Development Board, was evaluated as a management tool in predicting the spatial and temporal distribution of dissolved oxygen and biochemical oxygen demand in Plantation Canal. Predictions based on the QUAL-I model, which was verified only against midday summer-flow conditions, showed that...
Geologic framework of the Alaskan Continental Terrace in the Chukchi and Beaufort seas
Arthur Grantz, Mark L. Holmes, B. A. Kososki
1975, Open-File Report 75-124
Seismic, magnetic and gravity data indicate that the Chukchi and Beaufort epicontinental seas off northern Alaska overlie three sedimentary basins, or provinces, separated by structural highs of regional extent. The basins trend west to northwest and become increasingly marine from south to north. The Chukchi-Beaufort continental margin is similar to...
Studies for seismic zonation of the San Francisco Bay region
Roger D. Borcherdt
1975, Professional Paper 941-A
The analyses presented in the preceding six papers show that the geologic setting of the San Francisco Bay region has a dominant influence on potential earthquake hazards. The strong correlation between geologic conditions and the amount of earthquake damage in 1906 emphasizes the importance of this influence and demonstrates the...
Erosion and sediment transport in the Owens River near Bishop, California
Rhea P. Williams
1975, Water-Resources Investigations Report 75-49
Closure of Pleasant Valley Dam in 1954 has almost eliminated the supply of gravel to the 16-mile (25.7-kilometre) study reach of the Owens River. Because of armoring of the channel, scour has been limited to approximately 1 foot (0.3 metre) in the upper 2.3 miles (3.7 kilometres).This report presents information...
Notes on some experiments on the application of subtractive compensation to USGS seismic magnetic tape recording and playback systems
Jerry P. Eaton
1975, Open-File Report 75-663
The purpose of these experiments is to lay the groundwork for the implementation of subtractive compensation of the USGS seismic network tape playbacks utilizing the Develco model 6203 discriminators at a x1 playback speed. Although the Develco discriminators were designed for this application and a matching Develco compensation discriminator was...
Satellite relay and processing of hydrologic data in south Florida
E.T. Wimberly
1975, Water-Resources Investigations Report 75-12
Management of water in south Florida requires current hydrologic data on water levels and rainfall. This need is being met by a data processing system which provides near-real-time data from remote areas. The flow of data is from data-collection platforms at field sites via LANDSAT-1 satellite to the National Aeronautics...
Bibliography of United States Geological Survey reports on the geology and water resources of Texas, 1887-1974
1975, Water-Resources Investigations Report 75-20
Water-resources investigations in Texas consist of the collection of basic records through the hydrologic-data network, interpretive studies, and research projects. An office was established in Austin, Texas, in 1915 for surface-water studies, for ground-water studies in 1929, and water-quality studies in 1937. Previous investigations of the water resources of Texas...
Availability of ground water in Marion County, Indiana
William R. Meyer, J. P. Reussow, D. C. Gillies, W. J. Shampine
1975, Open-File Report 75-312
County constitute the most extensive aquifers in the county. Four areally distinct sand and gravel aquifers were mapped in the drift during the course of this study. The aquifer of greatest economic importance consists of sand and gravel deposits of glacial-outwash origin which coincide with the courses of the White...
Experimental results of atomic absorption analyses for indium and thallium in 803 nonmagnetic concentrates from Alaska
William C. Overstreet, George L. Crenshaw, Arthur E. Hubert, Sam Rosenblum, Ricke J. Smith
1975, Open-File Report 75-253
The development in the U.S. Geological Survey of rapid methods for the determination by atomic absorption spectrophotometry of indium and thallium at limits of detection as low as 0.2 ppm each in geologic materials affords great advantages over spectrographic methods in studies concerned with values at or near the crustal...
Water resources data for Missouri, water year 1974
Water Resources Division, U.S. Geological Survey
1975, Water Data Report MO-74-1
Water resources data for the 1974 water year for Missouri including records of streamflow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites, and records of water-quality data on the chemical and physical characteristics of surface water, are given in this report. In Part 1, records are included...
