Explore software used for all water resources applications, including general use, water quality and chemistry, groundwater, statistics and graphics, and surface water.
MODFLOW 6: USGS Modular Hydrologic Model
MODFLOW is a popular open-source groundwater flow model distributed by the U.S. Geological Survey.
Floodplain and Channel Evaluation Tool (FACET)
The Floodplain and Evaluation Tool (FACET) is an open-source python tool that maps the floodplain extent and derives reach-scale summaries of stream and floodplain geomorphic measurements from high-resolution digital elevation models (DEMs).
DTSGUI
DTSGUI is a USGS software tool to import, manage, parse/cull, georeference, analyze and visualize fiber-optic distributed temperature sensor data.
ModelMuse: A Graphical User Interface for Groundwater Models
ModelMuse is a Graphical User Interface for MODFLOW 6, MODFLOW-2005, MODFLOW-LGR, MODFLOW-LGR2, MODFLOW-NWT, MODFLOW-CFP, MODFLOW-OWHM, MT3DMS, SUTRA, PHAST, MODPATH, ZONEBUDGET and WellFootprint.
RSPARROW
RSPARROW, now available on the USGS GitLab repository, provides the first open-source version of the USGS SPARROW water-quality model
GCLAS (Graphical Constituent Loading Analysis System): A tool for computing loads of constituents transported in rivers
GCLAS is a program designed to compute daily and annual loadings of constituents transported in rivers.
Stream Channel and Floodplain Metric Toolbox
The Stream Channel and Floodplain Metric Toolbox was developed to demonstrate the feasibility of mapping fluvial geomorphic features from high-resolution bare-earth elevation data.
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.
Point-Source Load Estimation Tool (PSLoadEsT)
Software for generating reproducible load calculations for point source dischargers. Includes features to manage common data challenges such as duplicates, incompatible input tables, and missing nutrient concentration or effluent flow data.
