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.
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.
PHREEQC Version 3
PHREEQC Version 3 is a computer program for speciation, batch-reaction, one-Ddmensional transport, and inverse geochemical calculations.
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.
MODFLOW-USG: An Unstructured Grid Version of MODFLOW for Simulating Groundwater Flow and Tightly Coupled Processes Using a Control Volume Finite-Difference Formulation
MODFLOW-USG is an unstructured grid version of MODFLOW for simulating groundwater flow and tightly-coupled processes using a control volume finite-difference formulation.
GCLAS (Graphical Constituent Loading Analysis System)
GCLAS is a program designed primarily to compute daily and annual loadings of constituents transported in streamflow.
Scenario Evaluator for Electrical Resistivity (SEER) Survey Pre-Modeling Tool
The USGS Scenario Evaluator for Electrical Resistivity (SEER) is a quick and simple Excel-based decision support tool practitioners can use to assess the likely outcome of using two-dimensional (2D) electrical resistivity imaging for site characterization and remediation monitoring.
GRIDGEN: A Program for Generating Unstructured Finite-Volume Grids
GRIDGEN is a program for generating layered quadtree grids for MODFLOW-USG.
HYDROTHERM
The HYDROTHERM computer program simulates multi-phase ground-water flow and associated thermal energy transport in three dimensions. It can handle high fluid pressures, up to 1 x 10^9 Pa (104 atm), and high temperatures, up to 1,200 °C.
