C2VSimCG R374_rev

Published by California Department of Water Resources | State of California | Metadata Last Checked: January 27, 2026 | Last Modified: 2026-01-01T21:15:11.777256
### A new version of the C2VSimCG model is available here (https://data.cnra.ca.gov/dataset/c2vsimcg-version-2025-draft) Revised version of the C2VSimCG R374 (released April 27, 2018). Coarse grid California Central Valley Groundwater-Surface Water Simulation Model (C2VSimCG) 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 monthly timesteps. The C2VSimCG model includes 1392 cells and it has two versions in terms of the simulation period: water years 1922-2009 and water years 1973-2009.
