The San Joaquin-Tulare Conjunctive Use Model (SANTUCM) was developed to evaluate possible long-term scenarios for long term management of drainage and drainage related problems in the western San Joaquin Valley of California. The unique aspect of the conjunctive use model is its coupling of a surface water delivery operations model with a regional groundwater model. A salinity model has been added to utilize surface water model output and allow assessment of compliance with State Water Resources Control Board water quality objectives for the San Joaquin River. The results of scenario runs, performed to data, using the SANTUCM model show table lowering and consequent drainage reduction can be achieved through a combination of source control, land retirement and regional groundwater pumping. The model also shows that water transfers within the existing distribution system are technically feasible and might allow additional releases to be made from Friant Dam for water quality maintenance in the San Joaquin River. However, upstream of Mendota Pool, considerable stream losses to the aquifer are anticipated, amounting to as much as 70% of in-stream flow.
