Summary

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This digital dataset represents the area where lateral flow into and out of the Central Valley groundwater-flow system occurs. The General Head Boundary (GHB) is set to 0 and is only in the Delta and is specified in layer 1 where the groundwater system intersects the surface water system. The Central Valley encompasses an approximate 50,000 square-kilometer region of California. The complex hydrologic system of the Central Valley is simulated using [...]

Purpose

Cells simulating lateral flow into and out of the Central Valley groundwater system were used as input to MODFLOW-FMP, the USGS 3-dimensional finite-difference code used to simulate flow in the CVHM. Average monthly values of flow were used to examine the magnitude and extent of the groundwater flow in and out of the Sacramento-San Joaquin Delta. The CVHM is a tool that accounts for integrated, variable water supply and demand, and simulates surface-water and groundwater-flow across the entire Central Valley system.
