Geohydrologic framework of the Snake River plain regional aquifer system, Idaho and eastern Oregon
R.L. Whitehead
1992, Professional Paper 1408-B
The Snake River Plain in southern Idaho is a major geologic structure of uncertain origin. Surface geology is generally well defined, but subsurface geology is poorly defined below about 500 feet. Rocks that underlie the plain form the framework for a regional ground-water system that supplies large quantities of water...

Chemistry of the subalkalic silicic obsidians
Ray MacDonald, Robert L. Smith, John E. Thomas
1992, Professional Paper 1523
Nonhydrated obsidians are quenched magmatic liquids that record in their chemical compositions details of the tectonic environment of formation and of the differentiation mechanisms that affected their subsequent evolution. This study attempts to analyze, in terms of geologic processes, the compositional variations in the subalkalic silicic obsidians (Si02≥70 percent by...
Simulation of regional ground-water flow in the Cambrian-Ordovician aquifer system in the northern Midwest, United States: in Regional aquifer-system analysis
R.J. Mandle, A.L. Kontis
1992, Professional Paper 1405-C
A six-State area in the northern Midwest of the United States has become increasingly dependent on ground water from the Cambrian-Ordovician aquifer system, which consists of a sequence of sandstones, carbonate rocks, and shales. Ground-water withdrawals from the aquifer system began in the late 1800's and increased to approximately 684...
Numerical simulation of ground-water flow in the central part of the western San Joaquin Valley, California

The occurrence of selenium in agricultural drain-water in the central part of the western San Joaquin Valley, California, has focused concern on strategies for managing shallow, saline ground water. In order to assess alternatives to agricultural drains, a three-dimensional, finite-difference numerical model of the regional ground-water flow system was developed....

A generalized finite-difference formulation for the U.S. Geological Survey modular three-dimensional finite-difference ground-water flow model
Arlen W. Harbaugh
1992, Open-File Report 91-494
The U.S. Geological Survey's Modular Ground-Water Flow Model assumes that model nodes are in the center of cells and that transmissivity is constant within a cell. Based on these assumptions, the model calculates coefficients, called conductance, that are multiplied by head difference to determine flow between cells. Although these are...

1992, Water Supply Paper 2378
Seventeen methods for estimating ice-affected streamflow are evaluated for potential use with the U.S. Geological Survey streamflow-gaging station network. The methods evaluated were identified by written responses from U.S. Geological Survey field offices and by a comprehensive literature search. The methods selected and techniques used for applying the methods are...
