Software

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.

FLASH (Flow-Log Analysis of Single Holes) is a computer program for the analysis of borehole vertical flow logs.

Conduit Flow Process (CFP) allows simulation of laminar and turbulent flow within a standard MODFLOW layer and/or simulation of a hybrid model (one-dimensional pipe network coupled to MODFLOW).
 

SutraSuite is a collection of software for groundwater modeling in both two spatial dimensions (2D) and three spatial dimensions (3D).  It includes the SUTRA groundwater model, the SutraGUI pre-processor, the SutraPrep text-based preprocessor, and the SutraPolot post-processor.

ZONEBUDGET is a program for computing subregional water budgets for MODFLOW ground-water flow models.

STRMDEPL08—An Extended Version of STRMDEPL with Additional Analytical Solutions to Calculate Streamflow Depletion by Nearby Pumping Well

ZONECONC is a postprocessing program that tabulates concentration statistics from concentration data generated by MODFLOW-GWT.

SutraPrep  facilitates the creation of three-dimensional (3D) input datasets for the USGS ground-water flow and transport model SUTRA .

SutraPlot creates 2D and rotatable 3D plots from 2D and 3D SUTRA output data.
