A finite-element model for simulation of two-dimensional steady-state ground-water flow in confined aquifers
E. L. Kuniansky
1990, Open-File Report 90-187
A computer program based on the Galerkin finite-element method was developed to simulate two-dimensional steady-state ground-water flow in either isotropic or anisotropic confined aquifers. The program may also be used for unconfined aquifers of constant saturated thickness. Constant head, constant flux, and head-dependent flux boundary conditions can be specified in...

Evaluation of selected methods for determining streamflow during periods of ice effect
N.B. Melcher, J.F. Walker
1990, Open-File Report 90-554
Seventeen methods for estimating ice-affected streamflow are evaluated for potential use for 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 described...

Records of wells and chemical analyses of ground water in Deuel and Hamlin counties, South Dakota
K.M. Neitzert, D. S. Hansen
1990, Open-File Report 90-391
Well and chemical groundwater data contained in three tables were collected during a 5-year study started in 1971 to determine the geology and water resources of Deuel and Hamlin Counties, South Dakota. Physical, hydrologic, and geologic data for 3,228 wells and test holes have been entered into computer storage in...

Geologic mapping combined with structural, petrographic, and geochemical investigations were used to evaluate the motion and paleogeographic setting of the northern Nabitah fault zone. The orientation and asymmetry of small structures in three areas along the fault zone suggest that motion was primarily left-lateral strike slip. East of the fault...
