Explore software used for all water resources applications, including general use, water quality and chemistry, groundwater, statistics and graphics, and surface water.
SWToolbox Software Information
USGS and the U.S. Environmental Protection Agency (EPA) have combined their SWSTAT and DFLOW software programs into a new tool for the low-flow anlaysis, the SWToolbox.
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.
Software - MODFLOW
MODFLOW is the USGS's modular hydrologic model. MODFLOW is considered an international standard for simulating and predicting groundwater conditions and groundwater/surface-water interactions.
API - Stream Trace
The Streamer Trace API is a programming interface written in JavaScript designed to add up- and downstream traces to an ESRI ArcGIS API for JavaScript (ESRI JSAPI) web map using the same methods and services created for the Streamer application.
API - Graphing Water Information System (GWIS)
GWIS (Graphing Water Information System) Javascript library can create time-series plots of information measured at USGS hydrologic data collection sites across the US. Developed by the USGS Texas Water Science Center, the user-friendly interface integrates the open-source...
VS2DRTI Version 1.4
VS2DRTI is a graphical software package for simulating water flow, heat transport, and reactive solute 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.
Github - U.S. Geological Survey
Various projects on the USGS's public GitHub.
Water Resources Applications Software
The software and related documentation on these Web pages were developed by the U.S. Geological Survey (USGS) for use by the USGS in fulfilling its mission. The software can be used, copied, modified, and distributed without any fee or cost.
HEC-RAS
The purpose of this website is to enhance the support services provided to HEC-RAS customers. The HEC-RAS website provides a number of resources, which include helping the user download software, learn how to use HEC-RAS, resolve problems, report bugs, and suggest improvements to CEIWR-HEC products and service.
Montana StreamStats: a water-resources web application
StreamStats is a Web application that incorporates a Geographic Information System (GIS) to provide users with access to an assortment of analytical tools that are useful for a variety of water-resources planning and management purposes, and for engineering and design purposes.
SPARROW modeling: Estimating contaminant transport
What’s New: A new version of the SPARROW code is being developed in the R programming language. The advantage of R is that it is non-proprietary and does not require a license or software cost. The R – SPARROW code is now being completed and should be available early in CY18. Stay Tuned.
