MODPATH Observation Process (MODPATH-OBS)
The MODPATH-OBS (Hanson and others, 2013) computer program is designed to calculate simulated equivalents for observations related to advective groundwater transport that can be represented in a quantitative way by using simulated particle-tracking data.
MODFLOW-OWHM: One Water Hydrologic Flow Model
The One-Water Hydrologic Flow Model (MF-OWHM) (Hanson and others, 2014) is a MODFLOW-based integrated hydrologic flow model (IHM) that is the most complete version, to date, of the MODFLOW family of hydrologic simulators needed...
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.
Wellfootprint - A Map App for Visualizing Groundwater Withdrawals
Wellfootprint computes a raster map of groundwater withdrawals relative to a user-defined "Depth-Rate Index" (DRI), such as a recharge rate. Dividing each well's withdrawal rate by the length per time DRI yields an area for display for each well's 'footprint' as a circle around each well. Symbols for closely spaced wells are merged to visualize the combined withdrawals equitably.
VS2DI Version 1.3
VS2DI is a graphical software package for simulating fluid flow and solute or energy transport in variably saturated porous media.
PHAST - A Computer Program for Simulating Groundwater Flow, Solute Transport, and Multicomponent Geochemical Reactions
PHAST Is a computer program for simulating groundwater flow, solute transport, and multicomponent geochemical reactions.
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.
