Analysis of urban storm-water quality for seven basins near Portland, Oregon
Timothy L. Miller, Stuart W. McKenzie
1978, Open-File Report 78-662
Over a 1.5-year period, water-quality data were collected for seven small drainage basins in urban aeas of Portland, Oreg. Analysis of the data followed three approaches. First, the constituent concentrations were analyzed. Average concentrations of suspended sediment, settleable solids, and fecal coliform bacteria generally exceeded levels expected for secondary waste-treatment...
A statistical summary and listing of the spectrographic analyses of heavy mineral concentrate and conventional, sieved stream-sediment samples, Silver City area, New Mexico
K. C. Watts, J.R. Hassemer, D. F. Siems, J. M. Nishi
1978, Open-File Report 78-801
Geochemical sampling of a tier of eight 7 1/2-minute quadrangles bordered by latitudes 32° 45'and 33° 00' N. and longitudes 108° 00' and 108° 30' W. was begun in the fall of 1974 and continued seasonally until completion in the fall of 1976. These quadrangles are in southwest New Mexico...
Analyses and description of geochemical samples, Cranberry Wilderness Study Area, Pocahontas and Webster counties, West Virginia
J. M. Motooka, J.C. Negri, J. D. Sharkey, F. G. Lesure
1978, Open-File Report 78-215
Semiquantitative spectrographic and other analyses on 104 stream sediment and 100 rock and mineral samples are reported here in detail. Location for all samples are in universal Transverse Mercator (UTM) coordinates. Brief descriptions of rock and mineral samples are included. Rocks analyzed include sandstone and shale; two samples of pyrite...
Hydrologic information for land-use planning, Fairbanks vicinity, Alaska
Gordon L. Nelson
1978, Open-File Report 78-959
The flood plain on the Chena and Tanana Rivers near Fairbanks, Alaska, has abundant water in rivers and in an unconfined alluvial aquifer. The principal source of ground water is the Tanana River, from which ground water flows northwesterly to the Chena River. Transmissivity of the aquifer commonly exceed 100...
Water resources of the Lake Superior watershed, northeastern Minnesota
Perry G. Olcott, D.W. Ericson, P.E. Felsheim, W.L. Broussard
1978, Hydrologic Atlas 582
The Lake Superior watershed is mostly a highland, generally 1,200 feet (366 meters) to 2,000 feet (610 meters) above mean sea level. It extends from Duluth to the Canadian border. Both maximum and minimum altitudes for Minnesota occur in the watershed; 2.301 ft (701 ) at Eagle Mountain, about 12 mi...
Analyses of water, core material, and elutriate samples collected near Yazoo City, Mississippi (Yazoo Headwater Project)
Harold L. Leone, Alton J. Dupuy
1978, Open-File Report 78-792
Five core-material-sampling sites were chosen by the U.S. Army Corps of Engineers to represent areas of proposed dredging activity. Four receiving-water sites also were selected to represent the water that will contact the proposed dredged material. Chemical and physical analyses were performed upon core material and native-water samples from these...
Allocation of subsamples of Apollo 17 lunar rocks from the boulder at station 7, for study by the International Consortium
Jean A. Minkin, Carolyn L. Thompson, E. C. T. Chao
1978, Open-File Report 78-511
The International Consortium was organized, under the leadership of E. C. T. Chao, to conduct a systematic interdisciplinary study of four lunar rock samples (77135, 77115, 77075 and 77215) collected by the Apollo 17 astronauts as representative of the four lithologies they recognized in the boulder at station 7. Tables...
Mineral resources of the Craggy Mountain Wilderness Study Area, Buncombe County, North Carolina
Frank Gardner Lesure, A. E. Grosz, B. B. Williams, Gertrude C. Gazdik
1978, Open-File Report 78-1091
The Craggy Mountain Wilderness Study Area covers about 550 hectares of the Pisgah National Forest in the Blue Ridge Mountains of western North Carolina (fig. 1). The area is 21 km northeast of Asheville, Buncombe County, N.C., and 11 km southwest of Mount Mitchell, the highest point in eastern North...
Backwater at bridges and densely wooded flood plains, Bogue Chitto near Summit, Mississippi
B.E. Colson, C. O. Ming, George J. Arcement
1978, Hydrologic Atlas 592
New techniques for predicting water-surface profiles, needed in the design of economical, structurally sound, and environmentally compatible stream crossings, are under investigation.  The investigation has accelerated with the advent of digital computers capable of analyzing large quatities of data.  Among the techniques is the development of two-dimensional (2-D) digital models....
Users guide for distributed routing rainfall-runoff model
D.R. Dawdy, John C. Schaake Jr., William M. Alley
1978, Water-Resources Investigations Report 78-90
A computer program of a watershed model for routing urban flood discharges through a branched system of pipes or natural channels using rainfall as input has been developed and documented. The model combines soil-moisture-accounting and rainfall-excess components developed by Dawdy and others (1972) with the kinematic-wave routing method presented by...
