Explore software used for all water resources applications, including general use, water quality and chemistry, groundwater, statistics and graphics, and surface water.
PHREEQC Version 3
PHREEQC Version 3 is a computer program for speciation, batch-reaction, one-Ddmensional transport, and inverse geochemical calculations.
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.
MODFLOW 6: USGS Modular Hydrologic Model
MODFLOW is a popular open-source groundwater flow model distributed by the U.S. Geological Survey.
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.
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.
GSadjust: a graphical user interface for processing combined relative- and absolute-gravity surveys
GSadjust is a graphical user interface for processing relative-gravity surveys. It provides an interface for data selection, drift evaluation and correction, network adjustment, for data from modern relative (Scintrex, ZLS) and absolute (Micro-g LaCoste) gravity meters.
PHREEQ-N-AMDTreat
USGS developed, in cooperation with the Office of Surface Mining Reclamation and Enforcement, “user-friendly” aqueous geochemical modeling tools to simulate changes in water quality during passive and active treatment of acid mine drainage.
DGMETA (Dissolved Gas Modeling and Environmental Tracer Analysis)
DGMETA (Dissolved Gas Modeling and Environmental Tracer Analysis) is a Microsoft Excel-based computer program that is used for modeling air-water equilibrium conditions from measurements of dissolved gases and for computing concentrations of environmental tracers that rely on air-water equilibrium model results.
Python GIS Flood Tool (pygft)
The Python GIS Flood Tool (pygft) was designed to process stream, catchment, and elevation datasets in order to assess the extent and depth of flooding for each stream reach. The model itself is light-weight, created with the capability to scale to larger regions or CONUS (conterminous United States) scales.
Flow-Conditioned Parameter Grid Tools
The Flow-Conditioned Parameter Grid (FCPG) Tools are a Python 3 library to make FCPGs for either two-digit Hydrologic Unit Code (HUC2) regions, four-digit Hydrologic Unit Code (HUC4) regions, or other geospatial tiling schemes. These tools can be used in a Linux-based high performance computing (HPC) environment or locally on your system.
