Genesis of a zoned granite stock, Seward Peninsula, Alaska
Travis Hudson
1977, Open-File Report 77-35
A composite epizonal stock of biotite granite has intruded a diverse assemblage of metamorphic rocks in the Serpentine Hot Springs area of north-central Seward Peninsula, Alaska. The metamorphic rocks include amphibolite-facies orthogneiss and paragneiss, greenschist-facies fine-grained siliceous and graphitic metasediments, and a variety of carbonate rocks. Lithologic units within the...
A compilation of data from the July, 1976 Oroville, California seismic-refraction experiment
Mary Ann Spieth, David P. Hill
1977, Open-File Report 77-881
The August 1, 1975, Oroville, California, earthquake (Mb = 5.7) and its aftershocks focused considerable interest on current tectonic processes operating in the western foothills of the Sierra Nevada range. As part of an intensive study of this earthquake sequence, the United States Geological Survey with support from the California...
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...
Directory of local assistance centers of the National Water Data Exchange (NAWDEX)
Melvin D. Edwards
1977, Open-File Report 76-880
The National Water Data Exchange (NAWDEX), managed by the U.S. Geological Survey, has established a network of Local Assistance Centers throughout the United States and Puerto Rico to assist users of water data in identifying and locating the data they need. This Directory provides the information needed to contact any...
Water-level records for the northern High Plains of Colorado, 1973-77
Thomas J. Major, Ronald G. Borman, Kenneth D. Vaught
1977, Open-File Report 77-160
Water-level measurements were made in more than 600 wells during January 1977 in the northern High Plains of Colorado which includes about 9,500 square miles. Most of these wells were irrigation wells, but several stock and government-owned wells were also measured, especially in areas where there is little irrigation. Changes...
Trap-efficiency investigation, Bernalillo Floodwater Retarding Reservoir No. 1 (Piedra Lisa Arroyo) near Bernalillo, New Mexico, water years 1956-1974
D.E. Funderburg
1977, Open-File Report 77-261
The U.S. Geological Survey, in cooperation with the U.S. Soil Conservation Service, began an investigation of sedimentation of Bernalillo Floodwater Retarding Reservoir No. 1 (Piedra Lisa Arroyo) near Bernalillo, New Mexico in 1956. This investigation was part of a nationwide investigation of the trap efficiency of detention reservoirs. Reservoirs No....
Finite-difference model of two-dimensional, single, and two-phase heat transport in a porous medium - Version I
Charles R. Faust, James W. Mercer
1977, Open-File Report 77-234
Model documentation is presented for a two-dimensional (areal) heat-transport model capable of simulating both water- and vapor-dominated geothermal reservoirs that conform with the assumptions of the model. Finite-difference techniques are used to solve for the dependent variables pressure and enthalpy. The program is designed to simulate time-dependent problems such as...
Hydrologic data for the Vamoosa Aquifer, east-central Oklahoma
Joseph J. D’Lugosz, Roger G. McClaflin
1977, Open-File Report 77-487
Most of the data presented in this report were collected by the U.S. Geological Survey as part of a study of the geohydrology of the Vamoosa aquifer, in east-central Oklahoma, in cooperation with the Oklahoma Geological Survey. Some of the data listed in the tables were collected by Bingham and...
User's guide for U.S. Geological Survey rainfall-runoff models; revised 1977
Philip Hadley Carrigan Jr., David E. Bower, G.R. Dempster
1977, Open-File Report 77-884
Modified versions of the rainfall-runoff model described by Dawdy, Lichty, and Bergmann (1972) (see W72-11754) are used in the U.S. Geological Survey as a means of synthesizing flood discharges for small drainage areas. Synthesized flood discharges derived through use of long-term (60-70 year) rainfall and evaporation data, provide a more...
