Mathematical model of the West Bolsa Ground-water Basin, San Benito County, California

Simulation of the West Bolsa ground-water basin hydrology in California had provided values of basin recharge and discharge and nodally distributed values of transmissivity and storage coefficient. Average net recharge from April 1945 to March 1969 was 6.2 cubic feet per second and occurred as subsurace recharge and infiltration of rain and minor streamflow. Discharge from the basin during the same period was 8.1 cubic feet per second and occurred as pumping and leakage from confined parts of the basin. Values of transmissivity used in the model generally range from 3,300 to 20,000 feet squared per day. Values of storage coefficient used in the model range from 0.0005 to 0.10. (Woodard-USGS)
