Basin-margin depositional environments of the Fort Union and Wasatch Formations in the Buffalo-Lake De Smet area, Johnson County, Wyoming
Stanley L. Obernyer
1979, Open-File Report 79-712
The Paleocene Fort Union and Eocene Wasatch Formations along the east flank of the Bighorn Mountains in the Buffalo-Lake De Smet area, Wyoming, consist of continental alluvial fan, braided stream, and poorly drained alluvial plain deposits. The Fort Union conformably overlies the Cretaceous Lance Formation, which is marine in its...
Variation of alluvial-channel width with discharge and character of sediment
W. R. Osterkamp
1979, Water-Resources Investigations Report 79-15
Use of channel measurements to estimate discharge characteristics of alluvial streams has shown that little agreement exists for the exponent of the width-discharge relation. For the equation Q = aWAb, where Q is mean discharge and WA is active-channel width, it is proposed that the exponent, b, should be of...
Water quality of selected streams in the coal area of east-central Montana
P. W. McKinley
1979, Water-Resources Investigations Report 78-142
In October 1975 the U.S. Geological Survey established a network of nine data-collection stations on eight streams in Montana to monitor water quality in potential coal-mining areas. The report summarizes and evaluates the water-quality data that have been collected during the first 2 years (3 years for 1 station) of...
Reconnaissance geology of the Wadi Shuqub Quadrangle, sheet 20/41 A, Kingdom of Saudi Arabia
Robert C. Greene, Louis Gonzalez
1979, Open-File Report 79-1353
The Wadi Shuqub quadrangle (sheet 20/41 A) lies in the high mountainous part of the Hijaz plateau in west-central Saudi Arabia. The quadrangle is underlain chiefly by Precambrian layered metasedimentary and metavolcanic rocks that are intruded by plutons ranging in composition from gabbroic to granitic. The metasedimentary rocks include quartzite,...
Status of surface-water modeling in the U.S. Geological Survey
Marshall E. Jennings, Nobuhiro Yotsukura
1979, Circular 809
The U.S. Geological Survey is active in the development and use of models for the analysis of various types of surface-water problems. Types of problems for which models have been, or are being developed, include categories such as the following: (1)specialized hydraulics, (2)flow routing in streams, estuaries, lakes, and reservoirs,...
Effects of seepage from fly-ash settling ponds and construction dewatering on ground-water levels in the Cowles unit, Indiana Dunes National Lakeshore, Indiana
William R. Meyer, Patrick Tucci
1979, Water-Resources Investigations Report 78-138
Part of the Indiana Dunes National Lakeshore shares a common boundary with the Northern Indiana Public Service Company (NIPSCO). This area is underlain by unconsolidated deposits approximately 180 feet thick. NIPSCO accumulates fly ash from the burning of coal in electric-power generating units in settling ponds. Seepage from the ponds...
Experimental salinity alleviation at Malaga Bend of the Pecos River, Eddy County, New Mexico
John S. Havens, D. W. Wilkins
1979, Water-Resources Investigations Report 80-4
Upward-leaking brine, from a confined aquifer at the base of the Rustler Formation, mixes with fresher water in a shallow aquifer, resulting in discharge to the Pecos River in southern Eddy County, New Mexico, of about 0.5 cubic feet per second of saturated brine. Pumping brine from the aquifer at...
Estimation of floods of various frequencies for the small ephemeral streams in eastern Washington
W.L. Haushild
1979, Water-Resources Investigations Report 79-81
Equations were developed to estimate the magnitude of floods for various occurrence frequencies at ungaged sites on ephemeral streams that drain small, relatively undeveloped basins in the semiarid part of eastern Washington. The equations were developed from regression analyses that used the logarithms of the longitude indexes of gaged sites,...
Ground water in the vicinity of Capulin, New Mexico
D.L. Hart Jr., Christian Smith
1979, Water-Resources Investigations Report 79-79
The alluvial deposits within a closed basin near Capulin, New Mexico, are estimated to have 189,000 acre-feet of water in storage. These deposits have an estimated average transmissivity of 400 feet squared per day and represent the major source of ground water. Well yields range from a few gallons per...
