MT3D-USGS: Groundwater Solute Transport Simulator for MODFLOW

MT3D-USGS is a USGS updated release of the groundwater solute transport code MT3DMS. MT3D-USGS includes new transport modeling capabilities to accommodate flow terms calculated by MODFLOW packages that were previously unsupported by MT3DMS and to provide greater flexibility in the simulation of solute transport and reactive solute transport.

GSFLOW: Coupled Groundwater and Surface-Water Flow Model

Groundwater and Surface-water FLOW (GSFLOW) was developed to simulate coupled groundwater and surface-water resources. The model is based on the integration of the U.S. Geological Survey Precipitation-Runoff Modeling System (PRMS) and the U.S. Geological Survey Modular Groundwater Flow Model (MODFLOW).

Precipitation Runoff Modeling System (PRMS)

The Precipitation-Runoff Modeling System is a deterministic, distributed-parameter, physical process based modeling system developed to evaluate the response of various combinations of climate and land use on streamflow and general watershed hydrology.

Basin Characterization Model (BCM)

The Basin Characterization Model (BCM) models the interactions of climate with empirically measured landscape attributes including topography, soils, and underlying geology. It is a grid-based model that calculates the water balance for each 18-acre cell (270m resolution) in a given watershed in set time steps for the entire area.

MODFLOW-2005: USGS Three-Dimensional Finite-Difference Ground-Water Model

MODFLOW 6 is presently the core MODFLOW version distributed by the USGS, but MODFLOW-2005 (the previous core version) is still actively maintained and supported. MODFLOW-2005 simulates steady and nonsteady flow in an irregularly shaped flow system in which aquifer layers can be confined,...

SPARROW Modeling Program

SPARROW is a popular watershed modeling technique, distributed by the USGS, that estimates the amount of a contaminant transported from inland watersheds to larger water bodies by linking monitoring data with information on watershed characteristics and contaminant sources.

iRIC river flow and riverbed variation analysis

iRIC (International River Interface Cooperative) is a river flow and riverbed variation analysis software package which combines the functionality of MD_SWMS (Multi-Dimensional Surface-Water Modeling System), developed by the USGS, and RIC-Nays, developed by the Foundation of Hokkaido River Disaster Prevention Research Center.
