1. MFI2005 - Data Input (Entry) Program [USGS_MFI2005]
MFI2005 is a data input (entry) program for the U.S. Geological Survey modular three-dimensional finite-difference ground-water model called MODFLOW-2005. Data for MODPATH, a particle tracking program ...

2. MODFLOW-CDSS, a Version of MODFLOW-2005 with Modifications for Colorado Decision Support Systems [USGS_MODFLOW-CDSS]   PARENT SERF
MODFLOW-CDSS is a three-dimensional, finite-difference groundwater-flow model based on MODFLOW-2005, with two modifications. The first modification is the introduction of a Partition Stress Boundaries ...

3. MODOPTIM: A General Optimization Program for Ground-Water Flow Model Calibration and Ground-Water Management with MODFLOW [USGS_MODOPTIM]
MODOPTIM is a non-linear ground-water model calibration and management tool that simulates flow with MODFLOW-96 as a subroutine. A weighted sum-of-squares objective function defines optimal solutions ...

4. ModelMuse - A Graphical User Interface for MODFLOW-2005, PHAST, MODPATH, and ZONEBUDGET [USGS_ModelMuse]
ModelMuse is a graphical user interface (GUI) for the U.S. Geological Survey (USGS) models MODFLOW–2005 and PHAST. This software package provides a GUI for creating the flow and transport input file ...

5. WTAQ: Computer program for calculating drawdowns and estimating hydraulic properties for confined and water-table aquifers [USGS_WTAQ]
The computer program WTAQ calculates hydraulic-head drawdowns in a confined or water-table aquifer that result from pumping at a well of finite or infinitesimal diameter. The program is ...

6. An Excel Workbook for Identifying Redox Processes in Ground Water [USGS_Redox]
The reduction/oxidation (redox) condition of ground water affects the concentration, transport, and fate of many anthropogenic and natural contaminants. The redox state of a ground-water sample is ...

7. TracerLPM - An Excel Workbook for Interpreting Groundwater Age Distributions from Environmental Tracer Data [USGS_TracerLPM]
TracerLPM is an interactive Excel (2007 or later) workbook program for evaluating groundwater age distributions from environmental tracer data by using lumped parameter models (LPMs). Lumped parameter ...

8. BIOPLUMEIII - A 2D, Finite Diffference Model for Simulating the Natural Attenuation of Organic Contaminants in Ground-Water [USEPA_BIOPLUMEIII]
BIOPLUME III is a 2D, finite difference model for simulating the natural attenuation of organic contaminants in ground-water due to the processes of advection, dispersion, sorption, and ...

9. Arc Hydro Groundwater Data Model [CRWR_Arc_Hydro]
Arc Hydro is one of a number of data models developed for users of ArcGIS. Such models include transportation, geology, marine, petroleum, water utilities, and others, describing a variety of disciplines ...
