MODFLOW One-Water Hydrologic Flow Model—Conjunctive Use Simulation Software (MF-OWHM)
The MODLFOW One-Water Hydrologic Flow Model (MF-OWHM) (MF-OWHM; Boyce and others, 2020; Hanson and others, 2014) is a MODFLOW-2005-based integrated hydrologic flow model (IHM) that is the most complete version, to date, of the ...
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).
VS2DRTI - A Graphical Software Package for Simulating Water Flow, Heat Transport, and Reactive Solute Transport
VS2DRTI is a graphical software package for simulating water flow, heat transport, and reactive solute transport in variably saturated porous media.
MODFLOW-NWT: A Newton Formulation for MODFLOW-2005
MODFLOW-NWT is a Newton-Raphson formulation for MODFLOW-2005 to improve solution of unconfined groundwater-flow problems. MODFLOW-NWT is a standalone program that is intended for solving problems involving drying and rewetting nonlinearities of the unconfined groundwater-flow equation.
Thornthwaite Monthly Water Balance Model
The Thornthwaite water balance (Thornthwaite, 1948; Mather, 1978; 1979) uses an accounting procedure to analyze the allocation of water among various components of the hydrologic system. Inputs to the model are monthly temperature and precipitation. Outputs include monthly potential and actual evapotranspiration, soil moisture storage, snow storage, surplus, and runoff.
