A data input program (MFI2K) for the U.S. Geological Survey modular ground-water model (MODFLOW-2000)
Arlen W. Harbaugh
2002, Open-File Report 2002-41
MFI2K is a data-input (entry) program for the U.S. Geological Survey modular three-dimensional finite-difference ground-water model, MODFLOW-2000. MFI2K runs on personal computers. MFI2K supports the solute transport and parameter-estimation capabilities that are incorporated in MODFLOW-2000. Data for MODPATH, a particle-tracking program for use with MODFLOW-2000, also can be entered using...

Stephen E. Curtin, David C. Andreasen, Judith C. Wheeler
2002, Open-File Report 2002-445
This report presents a map showing the change in the potentiometric surface of the Magothy aquifer in the Magothy Formation of Cretaceous age in Southern Maryland for September 1975 and September 2001. The map, based on water level measurements in 54 wells, shows that during the 26-year period, the potentiometric...
SutraPrep, a pre-processor for SUTRA, a model for ground-water flow with solute or energy transport
Alden M. Provost
2002, Open-File Report 2002-376
SutraPrep facilitates the creation of three-dimensional (3D) input datasets for the USGS ground-water flow and transport model SUTRA Version 2D3D.1. It is most useful for applications in which the geometry of the 3D model domain and the spatial distribution of physical properties and boundary conditions is relatively simple. SutraPrep can...

Evaluation of artificial recharge in the Mojave River Ground-Water Basin, California
Christina L. Stamos, Peter Martin, Steven K. Predmore
2002, Open-File Report 2002-430
The Mojave River Basin relies almost entirely on ground water to meet the needs of its growing population and agriculture, which has resulted in overdraft conditions. Some of the ground-water management alternatives being proposed to mitigate the effects of overdraft include artificial recharge using water from the California State Water...
