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,...
Saline-seep development in the Hailstone Basin, northern Stillwater County, Montana
Barney D. Lewis, Stephen G. Custer, Marvin R. Miller
1979, Water-Resources Investigations Report 79-107
As a result of an increase in saline seep occurrence in Montana, a study was begun in 1974 to determine the hydrogeology of saline seeps in the Hailstone basin. The aquifer is composed of colluvium of Holocene age. The impermeable Cretaceous Niobrara Formation underlies the saturated zone basinwide. The ground-water...

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,...

The Alaskan Mineral Resource Assessment Program: Background information to accompany folio of geologic and mineral resource maps of the Talkeetna quadrangle, Alaska
Bruce L. Reed, G.C. Curtin, Andrew Griscom, S.W. Nelson, D.A. Singer, W. C. Steele
1979, Circular 775
The Talkeetna 1° by 3° quadrangle, which consists of about 17,155 km2 in south-central Alaska, was investigated by integrated field and laboratory studies in the disciplines of geology, geochemistry, geophysics, and Landsat data interpretation for the purpose of assessing its mineral resource potential. Past mineral production has been limited to...

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...
Distribution of nitrate and related nitrogen species in the unsaturated zone, Redlands and vicinity, San Bernardino County, California
John M. Klein, Wesley L. Bradford
1979, Water-Resources Investigations Report 79-60
Nitrogen in the unsaturated soil zone in the vicinity of Redlands in San Bernardino County, Calif., has been suspected as the source of nitrate in water from wells. Plans have been made to recharge the aquifer with imported surface water. If this occurs, the rising water table will intercept soluble...

An appraisal of pumping effects on the Edgeley Aquifer, La Moure County, North Dakota, as determined by a digital model
M. R. Burkart
1979, Open-File Report 79-748
A finite-difference digital model simulated hydrologic conditions in the Edgeley aquifer, which is an unconfined glacial-drift aquifer. The calibrated model supported the hypothesis that under natural steady-state conditions, recharge is from precipitation and discharge is through evapotranspiration. This hypothesis was further supported by comparing simulated water levels to observed water...
New geologic, ground magnetic, E-mode VLF, and radiometric surveys at Phillips Mine-Camp Smith uranium prospect, Westchester and Putnam Counties, New York
David L. Campbell, Richard I. Grauch, Connie J. Nutt
1979, Open-File Report 79-1078
This report updates U.S. Geological Survey Open-File Report 77-780 by including new field data taken in July 1978. A revised geologic map is included, as are new geophysical data from an approximately 0.3-km by 0.5-km area just northeast of and adjoining the area surveyed earlier. The pattern which had been...

Hydrogeologic features of the alluvial deposits in the Nowood River drainage area, Bighorn Basin, Wyoming
M. E. Cooley, William J. Head
1979, Open-File Report 79-1291
In the Nowood River drainage area, Wyoming, the principal deposits comprising the alluvial aquifer include the flood-plain and younger (generally undissected) alluvial-fan deposits and a unique boulder-fan gravel. Other deposits mapped, but virtually nonwater yielding, are the older (dissected) alluvial-fan, pediment, and terrace deposits. Terraces are capped by gravel and...
