C2VSimFG Version 1.0: The 1.0 version of the Fine Grid California Central Valley Groundwater-Surface Water Simulation Model (C2VSimFG Version 1.0 ) is a computer program that simulates water movement through the linked land surface, groundwater, and surface water flow systems in California’s Central Valley using the DWR-developed software, Integrated Water Flow Model Version 2015 (IWFM-2015). C2VSimFG Version 1.0 contains monthly historical stream inflows, surface water diversions, precipitation, evapotranspiration, and land use acreages from October 1973 through September 2015 (Data is available in the input files for 1922 through 2015). C2VSimFG Version 1.0 dynamically calculates crop water demands, allocates contributions from precipitation, soil moisture and surface water diversions, and calculates the groundwater pumping rates required to meet the remaining demand. It simulates the historical response of the Central Valley’s groundwater and surface water flow system to historical stresses and can also be used to simulate the response to projected stresses. DWR is providing C2VSimFG Version 1.0 to Groundwater Sustainable Agencies (GSAs) and other related entities as an optional tool that can be used to perform analysis during development and implementation of their Groundwater Sustainability Plans (GSPs).

The C2VSimFG Beta Model is available in a compressed zip format due to its size (3.5 GB uncompressed). The contents of the zip file include the model executables, model input files, and selected outputs from running the model and calculating zbudgets. The input files and parameter files are all in text files. Outputs are in text files and summaries have been developed and are contained in excel files. Within the zip file, there are 7 folders. The folder titled Bin contains the executables. The folder titled Budget contains a batch file and input file for creating budgets after the simulation has been completed. The folder titled Excel contains excel summaries of outputs of the Budgets and ZBudgets. The folder titled Preprocessor contains the geometry information for the model nodes, elements, streams, and layers. The folder titled Results contains the outputs from the model simulation, budgets, and Zbudgets. The folder titled Simulation contains all of the data for initial and boundary conditions as well as aquifer parameters. In addition, Simulation settings and features as well as the batch files for simulating the model are provided here. The folder titled Z-Budget contains the input files and batch files for running the ZBudgets using the model simulation results.
