GEOPACK - A comprehensive U.S. EPA geostatistical software system for conducting analysis of the spatial variability of one or more random functions. |
 |
HEC-HMS |
HEC-HMS - Hydrologic Modeling System flood hydrology software. Determine peak flow hydrographs for rainfall-runoff events in large river basins or small urban watersheds. |
 |
HEC-RAS |
HEC-RAS - 1D hydraulic water surface profile model for steady and unsteady flow for a full network of natural and constructed channels. |
| |
HSPF |
The HSPF Model (Hydrologic Simulation Program Fortran) is a U.S. EPA program for simulation of watershed hydrology and water quality for both conventional and toxic organic pollutants. |

HSSM (Hydrocarbon Spill Screening Model) is a U.S. EPA model which simulates subsurface releases of light nonaqueous phase liquids |
 |
HST3D |
HST3D - A Computer Code for Simulation of Heat and Solute Transport in Three-Dimensional Ground-Water Flow Systems |
| |
MOC |
MOC simulates 2D solute transport in flowing ground water |
| |
MOCDENSE |
MOCDENSE is a variable density ground-water flow and solute-transport model. This version of MOCDENSE simulates the flow in a cross-sectional plane rather than in an areal plane. |
 |
MODFLOW |
MODFLOW - USGS Modular Three-Dimensional Ground-Water Flow Model |
| |
Multimed |
MULTIMED (MULTIMEDia Assessment Model) simulates the fate and transport of contaminants leaching from a waste disposal facility into the multimedia (soil and air) environment. |
 |
PEST |
PEST - non-linear parameter estimation software for any numerical model. |
| |
PESTAN |
PESTAN- Pesticide Transport is a U.S. EPA program for evaluating the transport of organic solutes through the vadose zone to ground water. |
| |
PHREEQE |
PHREEQE is a USGS computer program designed to model geochemical reactions. |
| |
PLOTCHEM |
PLOTCHEM - A Water-quality data plotting software package |
| |
PRZM3 |
PRZM3 links PRZM and VADOFT to predict pesticide transport and transformation down through the crop root and vadose zone. |
| |
QUAL2EU |
Enhanced Stream Water Quality Model with Uncertainty Analysis is a U.S. EPA model for conventional pollutants in branching streams and well mixed lakes. |
| |
RECESS |
RECESS is a group of six computer programs (RECESS, RORA, PART, TRANS, CURV and STREAM) for describing the Recession of Ground-Water Discharge and for Estimating Mean Groundwater Recharge and Discharge from Streamflow Records. |
| |
RETC |
RETC - Retention Curve Program for Unsaturated Soils |
| |
RITZ |
RITZ is a menu-driven U.S. EPA model which permits decision makers to simulate the movement and fate of hazardous chemicals during land treatment of oily wastes. |
| |
VLEACH |
VLEACH, a One-Dimensional Finite-Difference Vadose Zone Leaching Model, is a U.S. EPA program which describes the movement of an organic contaminant within and between three phases: (1) as a solute dissolved in water, (2) as a gas in the vapor phase, and (3) as an adsorbed compound in the solid phase. |
| |
VS2DT |
VS2DT is a USGS program for flow and solute transport in variably-saturated, single-phase flow in porous media. A finite-difference approximation is used in VS2DT to solve the advection-dispersion equation. |
| |
WASP5 / DYNHYD5 |
WASP5, Water Quality Analysis Simulation Program, is a U.S. EPA model that simulates contaminant fate in surface waters. DYNHYD5 model is a simple hydrodynamic model that simulates variable tidal cycles, wind, and unsteady inflows. |
