CE-QUAL-W2 - Hydrodynamic and Water Quality Model
CE-QUAL-W2 is a water quality and hydrodynamic model in 2D (longitudinal-vertical) for rivers, estuaries, lakes, reservoirs and river basin systems. W2 models basic eutrophication processes such as temperature-nutrient-algae-dissolved oxygen-organic matter and sediment relationships.
MODFLOW-USG: An Unstructured Grid Version of MODFLOW for Simulating Groundwater Flow and Tightly Coupled Processes Using a Control Volume Finite-Difference Formulation
MODFLOW-USG is an unstructured grid version of MODFLOW for simulating groundwater flow and tightly-coupled processes using a control volume finite-difference formulation.
Scenario Evaluator for Electrical Resistivity (SEER) Survey Pre-Modeling Tool
The USGS Scenario Evaluator for Electrical Resistivity (SEER) is a quick and simple Excel-based decision support tool practitioners can use to assess the likely outcome of using two-dimensional (2D) electrical resistivity imaging for site characterization and remediation monitoring.
GRIDGEN: A Program for Generating Unstructured Finite-Volume Grids
GRIDGEN is a program for generating layered quadtree grids for MODFLOW-USG.
HYDROTHERM
The HYDROTHERM computer program simulates multi-phase ground-water flow and associated thermal energy transport in three dimensions. It can handle high fluid pressures, up to 1 x 10^9 Pa (104 atm), and high temperatures, up to 1,200 °C.
MODFLOW-USG model of groundwater flow in the Wood River Valley aquifer system in Blaine County, Idaho
Model archive for Wood River Valley groundwater-flow model
wrv R package repository
The R package wrv is for processing the groundwater-flow model of the Wood River Valley (WRV) aquifer system, south-central Idaho. The groundwater-flow model is described in the associated model report and model archive. Included in the package is MODFLOW-USG version 1.3, a U.S. Geological Survey (USGS) computer code that solves the groundwater-flow equation.
Water Use Site Retrieval - Lower Mississippi Gulf Arkansas
In 1977, the Congress of the United States recognized the need for uniform, current, and reliable information on water use and directed the U.S. Geological Survey (USGS) to establish a National Water-Use Information Program (NWUIP) to complement the Survey's data on the availability and quality of the Nations water resources.
Groundwater Age Mixtures and Contaminant Trends Tool (GAMACTT)
The USGS Groundwater Age Mixtures and Contaminant Trends Tool (GAMACTT) can be used to explore the effects of basic aquifer properties and well configurations on groundwater age mixtures in groundwater discharge and on contaminant trends from varying nonpoint-source contaminant input scenarios.
Exploration and Graphics for RivEr Trends (EGRET)
Exploration and Graphics for RivEr Trends (EGRET) is an R-package for the analysis of long-term changes in water quality and streamflow, including the water-quality method Weighted Regressions on Time, Discharge, and Season (WRTDS).
Multidimensional Surface-Water Modeling System (MD_SWMS)
The U.S. Geological Survey’s (USGS) Multi-Dimensional Surface-Water Modeling System (MD_SWMS) is a pre- and post-processing application for computational models of surface-water hydraulics.
