The Groundwater Toolbox: A Graphical and Mapping Interface for Analysis of Hydrologic Data
The Groundwater Toolbox is a graphical and mapping interface for analysis of hydrologic data. It provides methods to estimate many of the components of the water budget for a hydrologic basin, including precipitation, streamflow, base flow, runoff, groundwater recharge and evapotranspiration.
MODFLOW-GUI Version 4
MODFLOW-GUI is a preprocessor and postprocessor graphical-user interface for preparing MODFLOW-96, MODFLOW-2000, MODFLOW-2005, MOC3D, MODPATH, and ZONEBDGT input data and viewing model output for use within Argus Open Numerical Environments (Argus ONE).
MF2KtoMF05UC
MF2KtoMF05UC is a program to convert MODFLOW-2000 files to MODFLOW-2005 and UCODE_2005 files.
Model Viewer: A Program For Three-Dimensional Visualization of Ground-water Model Results
ModelViewer is a program for three-dimensional visualization of groundwater model results.
Wellfootprint - A Map App for Visualizing Groundwater Withdrawals
Wellfootprint computes a raster map of groundwater withdrawals relative to a user-defined "Depth-Rate Index" (DRI), such as a recharge rate. Dividing each well's withdrawal rate by the length per time DRI yields an area for display for each well's 'footprint' as a circle around each well. Symbols for closely spaced wells are merged to visualize the combined withdrawals equitably.
VS2DI Version 1.3
VS2DI is a graphical software package for simulating fluid flow and solute or energy transport in variably saturated porous media.
Water, Energy, and Biogeochemical Model (WEBMOD)
The Water, Energy, and Biogeochemical Model (WEBMOD) uses the framework of the U.S. Geological Survey (USGS) Modular Modeling System (MMS) to simulate fluxes of water and solutes through watersheds. WEBMOD divides watersheds into model response units (MRU) where fluxes and reactions are simulated for several hillslope reservoir types.
Groundwater Transport Process (GWT)
Groundwater Transport Process (GWT) is a three-dimensional ground-water flow and solute-transport model integrated with MODFLOW-2000.
MoisturEC: R-based GUI to combine electrical conductivity data with point moisture measurements
MoisturEC is an R-based GUI used to combine electrical conductivity (EC) data with point moisture measurements for an updated moisture estimate capitalizing on the accuracy of point moisture measurements and the spatial coverage of EC data.
FloPy: Python Package for Creating, Running, and Post-Processing MODFLOW-Based Models
FloPy is a Python package for creating, running, and post-processing MODFLOW-based models.
MODPATH: A Particle-Tracking Model for MODFLOW
MODPATH is a particle-tracking post-processing model that computes flow paths using output from MODFLOW.
CE-QUAL-W2 - Hydrodynamic and Water Quality Model
CE-QUAL-W2 is a water quality and hydrodynamic model in 2D (longitudinal-vertical) for rivers, estuaries, lakes, reservoirs and river basin systems. W2 models basic eutrophication processes such as temperature-nutrient-algae-dissolved oxygen-organic matter and sediment relationships.
