Flood-prone area maps of three sites along the Trans-Alaska Pipeline, Alaska
Robert D. Lamke, Stanley H. Jones
1980, Open-File Report 80-209
The Bureau of Land Management requested on May 3, 1979 that the U.S. Geological Survey determine the base (100-year) flood-plain limits at three sites (fig. 1) along the Trans-Alaska Pipeline System Highway (Haul Road) between the Yukon River and Prudhoe Bay in order to issue land-use permits. The Alaska Department...
Channel erosion and sediment transport in Pheasant Branch basin near Middleton, Wisconsin; a preliminary report
R. Stephen Grant, Gerald Goddard
1980, Open-File Report 80-161
The purpose of this 5-year study is to (1) evaluate the sediment transport, streamflow characteristics, and stream-channel morphology, (2) relate the above to land-use practices; and (3) evaluate the effect that changes in land-use practices will have on Pheasant Branch basin near Middleton, Wis. This report presents findings of sediment...
Behavioral and catastrophic drift of invertebrates in two streams in northeastern Wyoming
David J. Wangsness, David A. Peterson
1980, Open-File Report 80-1101
Invertebrate drift samples were collected in August 1977 from two streams in the Powder River structural basin in northeastern Wyoming. The streams are Clear Creek, a mountain stream, and the Little Powder River, a plains stream. Two major patterns of drift were recognized. Clear Creek was sampled during a period...
Distribution of nitrate in the unsaturated zone, Highland-East Highlands area, San Bernardino County, California
John M. Klein, Wesley L. Bradford
1980, Water-Resources Investigations Report 80-48
Nitrogen in the unsaturated soil zone in the Highland-East Highlands area of San Bernardino County, Calif., has been suspected as the source of nitrate in water from wells. Plans to recharge the local aquifers with imported surface water would raise the water table and intercept that nitrogen. This study was...
Statistical analyses of surface-water-quality variables in the coal area of southeastern Montana
J. R. Knapton, Rodger F. Ferreira
1980, Water-Resources Investigations Report 80-40
Since 1974 a network of water-quality stations has been operated in the coal area of southeastern Montana. This report updates a previous report with 2 years of additional data collection and presents statistics and regression equations for water-quality variables. The most apparent feature of the study is the variability of...
Streamflow characteristics of the Yellowstone River Basin, Montana, through 1976
L. Grady Moore, Ronald R. Shields
1980, Water-Resources Investigations Report 80-41
Statistical summaries of streamflow data for selected stream-gaging and crest-stage gage sites are presented in this report to aid in appraising the hydrology of the Yellowstone River basin, Montana. Streamflow records presented for 45 gaging stations and 45 crest-stage gages for the period of record. Streamflow record collection in the...
Summary appraisals of the nation's ground-water resources – Caribbean region
Fernando Gómez-Gómez, James E. Heisel
1980, Professional Paper 813-U
The Caribbean Region consists of the Commonwealth of Puerto Rico (8,990 km2 (square kilometers)) and the U.S. Virgin Islands (350 km2). The mean annual precipitation varies locally from a high of 5,000 mm (millimeters) to a low of 730 mm. Maximum precipitation occurs within the peaks of Sierra de Luquillo,...
