Hydrologic Data for Urban Studies in the Fort Worth, Texas Metropolitan Area, 1975
R.M. Slade Jr., J.M. Taylor
1977, Open-File Report 77-266
This report contains rainfall and runoff data collected during the 1975 water year for Sycamore Creek, Sycamore Creek tributary , Dry Branch, and Little Fossil Creek study areas in Fort Worth, Texas. The information will be useful in determining the extent to which progressive urbanization will affect the yield and...
Paleozoic-Mesozoic boundary in the Berry Creek Quadrangle, northwestern Sierra Nevada, California
Anna Martta Hietanen
1977, Professional Paper 1027
Structural and petrologic studies in the Berry Creek quadrangle at the north end of the western metamorphic belt of the Sierra Nevada have yielded new information that helps in distinguishing between the chemically similar Paleozoic and Mesozoic rocks. The distinguishing features are structural and textural and result from different degrees...
Thermal loading of natural streams
Alan P. Jackman, Nobuhiro Yotsukura
1977, Professional Paper 991
The impact of thermal loading on the temperature regime of natural streams is investigated by mathematical models, which describe both transport (convection-diffusion) and decay (surface dissipation) of waste heat over 1-hour or shorter time intervals. The models are derived from the principle of conservation of thermal energy for application to...
Density and porosity estimates from borehole gravity data in the Castle Pines #3, #2, and #1 water wells, Douglas County, Colorado
Keith A. Byerley, J. W. Schmoker
1977, Open-File Report 77-875
Borehole gravity surveys were carried out in the Castle Pines #3, #2, and #1 water wells using the U.S. Geological Survey-LaCoste and Romberg borehole gravity meter (McCulloh and others, 1967a; McCulloh and others, 1967b). The objectives were to estimate the density and porosity of the formations penetrated, and to determine...
Stochastic analysis of particle movement over a dune bed
Baum K. Lee, Harvey E. Jobson
1977, Professional Paper 1040
Stochastic models are available that can be used to predict the transport and dispersion of bed-material sediment particles in an alluvial channel. These models are based on the proposition that the movement of a single bed-material sediment particle consists of a series of steps of random length separated by rest...
Quality of rivers of the United States, 1975 water year; based on the National Stream Quality Accounting Network (NASQAN)
John C. Briggs, John F. Ficke
1977, Open-File Report 78-200
The National Stream Quality Accounting Network (NASQAN) was established by the U.S. Geological Survey to provide a nationally uniform basis for continuously assessing the quality of U.S. rivers. Stations generally are at the downstream end of hydrologic accounting units in order to measure the quantity and quality of water flowing...
