Quality of streams in the Bull Mountains region, south-central Montana
J. R. Knapton
1982, Water-Resources Investigations Report 82-2
In October 1977, water-quality monitoring stations were established on five small streams that drain the Bull Mountains and also on the Musselshell River to document present water-quality conditions in a coal area of south-central Montana. Relatively static water-quality conditions exist throughout the annual flow cycle on the small streams but...
Water levels in Nassau County Sewer Districts 2 and 3, Long Island, New York, 1978-79
H. F. Ku, D. L. Simmons
1982, Water-Resources Investigations Report 82-4017
Prior to development on Long Island, about 95 percent of total streamflow originated as groundwater seepage from the upper glacial aquifer; the remaining 5 percent consisted of direct storm runoff. Thus, the streams on Long Island function as groundwater drains. Their flow in dry weather is directly controlled by groundwater...
Analysis of three tests of the unconfined aquifer in southern Nassau County, Long Island, New York
J.B. Lindner, T. E. Reilly
1982, Water-Resources Investigations Report 82-4021
Drawdown and recovery data from three 2-day aquifer tests (OF) the unconfined (water-table) aquifer in southern Nassau County, N.Y., during the fall of 1979, were analyzed. Several simple analytical solutions, a typecurve-matching procedure, and a Galerkin finite-element radial-flow model were used to determine hydraulic conductivity, ratio of horizontal to vertical...
Map showing the potentiometric surface of the Magothy Aquifer in southern Maryland, September 1982
Frederick K. Mack, Judith C. Wheeler, Stephen E. Curtin
1982, Water-Resources Investigations Report 83-4282
A map was prepared that shows the potentiometric surface of the Magothy aquifer in southern Maryland in September 1982. The map is based on measurements from a network of 83 observation wells. The highest levels of the potentiometric surface, 57 and 58 feet above sea level, were measured near the...
Suspended sediment in selected streams of southeastern Montana
D. W. Litke
1982, Water-Resources Investigations Report 82-4087
The relatively flat Badger Road area near Fairbanks occupies part of the alluvial plain of the Chena and Tanana Rivers and is underlain by scattered areas of permafrost. The water table of the high-transmissivity aquifer that underlies the area is generally shallower than 15 feet, fluctuates seasonally about 2 feet,...
A data-management system for areal interpretive data for the High Plains in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming
R. R. Luckey, C.F. Ferrigno
1982, Water-Resources Investigations Report 82-4072
The High Plains Regional Aquifer System Analysis has developed a regional water-resources (and related) data storage and retrieval system to organize and preserve areal interpretative data. The system is general and can easily be adapted for other studies. This report documents the High Plains data base as well as the...
Streamflows and channels of the Green River basin, Wyoming
H. W. Lowham
1982, Water-Resources Investigations Report 81-71
Width, depth, cross-sectional area, and velocity of streamflow were depicted for 51 gaged sites in or near the Green River basin of Wyoming by summarizing data obtained from current-meter discharge measurements. Using these at-a-station relations as a base, regional relations were then developed that characterize hydraulic features of streams throughout...
Percentage change in saturated thickness of the High Plains Aquifer, west-central Kansas, 1950 to average 1980-82
Marilyn E. Pabst
1982, Open-File Report 82-1010
A statistical technique, called kriging, was programmed for a computer to interpolate hydrologic data based on a network of 296 measured values in west-central Kansas and eastern Colorado. The computer program generated estimated values of selected hydrologic data at the center of each 1-mile section in the Western Kansas Groundwater...
Characteristics of suspended sediment in the San Juan River near Bluff, Utah
K. R. Thompson, J. C. Mundorff
1982, Water-Resources Investigations Report 82-4104
Fluvial-sediment data were collected for the San Juan River near Bluff beginning in 1914 and terminating in 1980. A double-mass curve showed a change in relationship between annual suspended-sediment discharge and annual stream discharge between the water years 1941-44 and 73. Possible causes for these changes in laboratory procedures, and...
Techniques for estimating flood discharges for unregulated streams in New Mexico
Richard P. Thomas, Robert L. Gold
1982, Water-Resources Investigations Report 82-24
Equations for estimating flood magnitudes at selected recurrence intervals from 2 to 500 years were developed using multiple-regression analyses. These equations relate flood magnitudes to basin characteristics, contributing drainage area and site altitude, and only are applicable to unregulated streams in New Mexico that are relatively unaffected by urban runoff....
