Use of selected basin characteristics to estimate mean annual runoff and peak discharges for ungaged streams in drainage basins containing strippable coal resources, northwestern New Mexico
H.R. Hejl
1984, Water-Resources Investigations Report 84-4260
Equations in this report can be used to estimate mean annual runoff and peak discharges for 2-, 5-, 10-, 25-, and 100-year recurrence intervals for ungaged streams in drainage basins containing strippable coal resources in northwestern New Mexico. These streamflow characteristics are related to basin characteristics that were found to...
Availability of ground water from the alluvial aquifer on the Nisqually Indian Reservation, Washington
W. E. Lum II
1984, Water-Resources Investigations Report 83-4185
A digital model using finite-difference techniques was constructed to simulate ground-water flow in an alluvial aquifer on the Nisqually Indian Reservation. The maximum long-term rate of pumping from individual wells, based on available data, is about 0.75 cubic feet per second (340 gallons per minute). Data on the extent, hydraulic...
Ground-water resources of the White River basin, Randolph County, Indiana
W.W. Lapham, L. D. Arihood
1984, Water-Resources Investigations Report 83-4267
The two major aquifer systems in Randolph County, Indiana are sand and gravel and bedrock (limestone, dolomite, and shale of Silurian to Odovician age). The average thickness of the sands and gravels is 15 ft, and the aquifers are areally discontinuous. The bedrock aquifer underlies the entire study area and...
A reconnaissance of the water resources of the Shoalwater Bay Indian Reservation and adjacent areas, Pacific County, Washington, 1978-1979
W. E. Lum
1984, Water-Resources Investigations Report 83-4165
A 1978-79 reconnaissance of the quantity and quality of water in the Shoalwater Bay Indian Reservation yielded information needed by the Shoalwater Bay Indian Tribe to plan future use of these resources. Ground water from the local artesian aquifer is suitable for most uses and it is estimated that yield...
International Strategic Minerals Inventory summary report; phosphate
Ulrich H. Krauss, Henning G. Saam, Helmut Schmidt
1984, Circular 930-C
Major world resources of phosphate, a strategic mineral commodity, are described in this summary report of information in the International Strategic Minerals Inventory {ISMI}. ISMI is a cooperative data-collection effort of earth-science and mineral-resource agencies in Australia, Canada, the Federal Republic of Germany, the Republic of South Africa, and the...
Physical basis and potential estimation techniques for soil erosion parameters in the Precipitation-Runoff Modeling System (PRMS)
W. P. Carey, Andrew Simon
1984, Water-Resources Investigations Report 84-4218
Simulation of upland-soil erosion by the Precipitation-Runoff Modeling System currently requires the user to estimate two rainfall detachment parameters and three hydraulic detachmment paramenters. One rainfall detachment parameter can be estimated from rainfall simulator tests. A reformulation of the rainfall detachment equation allows the second parameter to be computed directly....
Potential ground-water level changes in the Mississippi River alluvial aquifer in response to proposed navigation improvements on the Yazoo River in Mississippi
A. G. Lamonds, J. M. Kernodle
1984, Water-Resources Investigations Report 84-4039
A proposed navigation project on the Yazoo River between Vicksburg and Greenwood, Mississippi, will increase minimum river stages by more than 19 feet at the site of the proposed lock and dam near Vicksburg, and will decrease minimum river stages by 2 to 7 feet in much of the upper...
Cost-effectiveness of the stream-gaging program in Alaska
R. D. Lamke
1984, Water-Resources Investigations Report 84-4096
This report documents the results of a study of the cost-effectiveness of the stream-gaging program in Alaska. Data uses and funding sources were identified for the 110 continuous stream-gaging stations that were being operated in September 1983 with a budget of about $1,700,000 per year.However, for the purposes of the...
Planning report for the Gulf Coast Regional Aquifer-System Analysis in the Gulf of Mexico coastal plain, United States
Hayes F. Grubb
1984, Water-Resources Investigations Report 84-4219
Large quantities of water for municipal, industrial and agriculture use are supplied from the aquifers in Tertiary and younger sediments over an area of about 225,000 square miles in the Coastal Plain of Alabama, Arkansas, Florida, Illinois, Kentucky, Louisiana, Mississippi, Missouri, Tennessee, and Texas. Three regional aquifer systems, the Mississippi...
Flood-discharge profiles of selected streams in Rockland County, New York
Richard Lumia
1984, Water-Resources Investigations Report 84-4049
Flood-discharge profiles of 10 streams in Rockland County at six recurrence intervals ranging from 2 to 100 years are presented. Synthetic flood-frequency estimates were derived for nine rainfall-runoff sites from calibrated models; observed flood-frequency estimates were derived for three sites having long-term discharge records. A variance-weighting technique was applied to...
Ground water in the Fresno area, California; preliminary report
H. T. Mitten
1984, Water-Resources Investigations Report 83-4246
The U.S. Geological Survey, in cooperation with Fresno County, is developing a computer model of the unconfined aquifer system in the Fresno area. In the area, consolidated rocks are overlain by unconsolidated deposits. The unconsolidated deposits are divided into a lower fine-grained unit and an overlying coarse-grained unit. The system...
Interpolating water-table altitudes in west-central Kansas using kriging techniques
L. E. Dunlap, Joseph M. Spinazola
1984, Water Supply Paper 2238
Kriging is a regionalization technique that incorporates the autocorrelation between known data values in its estimation of values at unmeasured sites. This technique is reproducible, accepts irregularly spaced data, uses only measured values closely surrounding points at which values are estimated, is an exact interpolator at measured data points, and...
Hydrogeology of eastern Michaud Flats, Fort Hall Indian Reservation, Idaho
N.D. Jacobson
1984, Water-Resources Investigations Report 84-4201
Groundwater in Michaud Flats, southeastern Idaho, is developed extensively for irrigation and industry. Extensive clay beds overlie the Bighole Basalt and Sunbeam Formation, which yield most of the water for irrigation and industrial wells; artesian aquifers in these rock units have heads below land surface and near those in the...
