Abstract: The subsurface drainage and drainage-related problems in the San Joaquin Valley cost millions of dollars to the State and local economy every year. A number of actions have been proposed for management of drainage problem, which contain several components such as source control, drainage reuse, evaporation system, land retirement or change in land use practices, groundwater management, discharge to San Joaquin River, protection and restoration of wildlife habitat, and institutional changes. Four alternative drainage management scenarios are developed from a combination of these components. These scenarios are analyzed using the San Joaquin-Tulare conjunctive use model (SANTUCM) developed for this project. The scenario runs suggest that the best drainage management practice can be achieved through a combination of source control, change in land use practices, and increased groundwater pumping in selected areas, as well as water exchanges and transfers within the existing distribution system.
