Basic (BAS) data file (model grid, active model cells, and hydraulic-head values) for the Central Valley Hydrologic Model (CVHM)
This digital dataset defines the model grid, active model cells in the 10 model layers, and hydraulic-head values 
in the 10 model layers used to initiate the transient hydrologic model of the Central Valley flow system. The 
Central Valley encompasses an approximate 50,000 square-kilometer region of California. The …
