DGMETA (Version 1): Dissolved Gas Modeling and Environmental Tracer Analysis Computer Program
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. DGMETA can solve for the temperature, salinity, excess air, fractionation of gases, or
CalPUR-LUE
MODFLOW One-Water Hydrologic Flow Model (MF-OWHM)
The MODFLOW One-Water Hydrologic Flow Model (MF-OWHM) is an integrated hydrologic model designed for the analysis of conjunctive-use management.
MODFLOW 6 - LACP
pyGSFLOW v1.0.0
Batteries Included Fortran Library (BiF-lib), version 1.0.0
Groundwater Age Mixtures & Contaminant Trends Tool (GAMACTT)
Use this Groundwater Age Mixtures and Contaminant Trends Tool (GAMACTT) 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.
TracerLPM
An Excel® Workbook for Interpreting Groundwater Age Distributions from Environmental Tracer Data
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.
CRT: Cascade Routing Tool to Define and Visualize Flow Paths for Grid-Based Watershed Models
The U.S. Geological Survey Cascade Routing Tool (CRT) is a computer application for watershed models that include the coupled Groundwater and Surface-water FLOW model GSFLOW and the Precipitation-Runoff Modeling System (PRMS). CRT generates output to define cascading surface and shallow subsurface flow paths for grid-based model domains.
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.
Central Valley Hydrologic Model (CVHM)
The Central Valley Hydrologic Model (CVHM) is an extensive, detailed three-dimensional (3D) computer model of the hydrologic system of the Central Valley (Faunt, 2009). The Central Valley Hydrologic Model (CVHM) simultaneously accounts for changing water supply and demand across the landscape, and simulates surface water and groundwater flow across the entire Central Valley.
