Estimation of flood peaks from channel characteristics in Ohio
D.K. Roth
1985, Water-Resources Investigations Report 85-4175
Regression equations were developed to estimate flood peaks with selected recurrence intervals of 2 to 100 years for Ohio streams with alluvial and bedrock channels. CHannel-geometry characteristics, rather than basin characteristics, were used as independent variables. Width of active channel was the only channel-geometry characteristic significant at the 5-percent level...
Trend analysis of weekly acid rain data, 1978-83
Terry L. Schertz, Robert M. Hirsch
1985, Water-Resources Investigations Report 85-4211
There are 19 stations in the National Atmospheric Deposition Program which operated over the period 1978-83 and were subsequently incorporated into the National Trends Network in 1983. The precipitation chemistry data for these stations for this period were analyzed for trend, spatial correlation, seasonality, and relationship to precipitation volume. The...
Annual suspended-sediment loads in the Colorado River near Cisco, Utah, 1930-82
K. R. Thompson
1985, Water-Resources Investigations Report 85-4011
The Colorado River upstream of gaging station 09180500 near Cisco, Utah, drains about 24,100 square miles in Utah and Colorado. Altitudes in the basin range from 12,480 feet near the headwaters to 4,090 feet at station 09180500. The average annual precipitation for 1894-1982 near the station was 7.94 inches. The...
Water-quality characteristics of streams in the Piceance Creek and Yellow Creek drainage basins, northwestern Colorado, water years 1977-81
R.L. Tobin, H.E. Stranathan, K.J. Covay
1985, Water-Resources Investigations Report 84-4261
Physical and chemical data for streams in the Piceance Creek and Yellow Creek drainage basins, Colorado collected during the 1977-81 water years are summarized. Stream temperatures ranged from -0.5 to 35.0 degrees Celsius and were warmest near the downstream reaches of Piceance and Yellow Creeks. Minimum concentrations of dissolved oxygen...
Hydrology of the Reelfoot Lake basin, Obion and Lake counties, northwestern Tennessee
C. H. Robbins
1985, Water-Resources Investigations Report 85-4097
Nine maps describe the following water resources aspects of the Reelfoot Lake watershed: Map 1-Surface water gaging stations, lake level, and locations of observation wells, rainfall stations and National Weather Service rainfall stations; Maps 2 and 3-water level contours, river stage, groundwater movement; Maps 4 and 5-grid blocks simulating constant...
Geohydrology of test well USW H-3, Yucca Mountain, Nye County, Nevada
William Thordarson, F. E. Rush, S. J. Waddell
1985, Water-Resources Investigations Report 84-4272
Test well USW H-3 is one of several wells drilled in the southwestern part of the Nevada Test Site for hydraulic testing, hydrologic monitoring, and geophysical logging. The work was performed in cooperation with the U.S. Department of Energy. The rocks penetrated by the well to a total depth of...
Phase I summary and phase II plan for comparing regulated with unregulated streamflow in the Yakima River at Union Gap, Washington
C.H. Swift
1985, Water-Resources Investigations Report 83-4015
A preliminary investigation of the effects of reservoir storage and canal diversion on the flow of the Yakima River at Union Gap , Washington indicates that those effects are measurable and substantial--on the average causing a reduction of roughly one-quarter from the unregulated flow. Preliminary computations of the unregulated flow...
Cost-effectiveness of the stream-gaging program in the Hawaii District
I. Matsuoka, R. Lee, W. O. Thomas
1985, Water-Resources Investigations Report 84-4126
This project documents the results of a study of the cost-effectiveness of the stream-gaging program in the Hawaii District. The stream gages in the District were divided into two groups, the State of Hawaii and the Other Pacific Areas. Data uses and funding sources were identified for the 124 continuous...
Distribution of polychlorinated biphenyls in the Housatonic River and adjacent aquifer, Massachusetts
Frederick B. Gay, Michael H. Frimpter
1985, Water Supply Paper 2266
Polychlorinated biphenyls (PCB's) are sorbed to the fine-grained stream-bottom sediments along the Housatonic River from Pittsfield, Massachusetts, southward to the Massachusetts-Connecticut boundary. The highest PCB concentrations, up to 140,000 micrograms per kilogram, were found in samples of bottom material from a reach of the river between Pittsfield and Woods Pond...
Hydrologic factors affecting lake-level fluctuations in Big Marine Lake, Washington County, Minnesota
R. G. Brown
1985, Water-Resources Investigations Report 85-4176
A study by the U.S. Geological Survey from 1981 through 1984, in cooperation with the Carnelian-Marine Watershed District and the Minnesota Department of Natural Resources, investigated the causes of large lake-level fluctuations at Big Marine Lake. Historic records document that Big Marine Lake has changed substantially in surface area during...
Design of a sediment data-collection program in Kansas as affected by time trends
P. R. Jordan
1985, Water-Resources Investigations Report 85-4204
Data collection programs need to be re-examined periodically in order to insure their usefulness, efficiency, and applicability. The possibility of time trends in sediment concentration, in particular, makes the examination with new statistical techniques desirable. After adjusting sediment concentrations for their relation to streamflow rates and by using a seasonal...
Estimating annual suspended-sediment loads in the northern and central Appalachian Coal region
G. F. Koltun
1985, Water-Resources Investigations Report 85-4215
Multiple-regression equations were developed for estimating the annual suspended-sediment load, for a given year, from small to medium-sized basins in the northern and central parts of the Appalachian coal region. The regression analysis was performed with data for land use, basin characteristics, streamflow, rainfall, and suspended-sediment load for 15 sites...
Seismicity map of the State of Montana
B.G. Reagor, C. W. Stover, S. T. Algermissen
1985, Miscellaneous Field Studies Map 1819
This map is one of a series of seismicity maps produced by the U. S. Geological Survey that show earthquake data of individual states or groups of states at the scale of 1:1,000,000. This map shows only those earthquakes with epicenters located within the boundaries of Montana, even though earthquakes...
