A simulation model was developed that accounts for major processes governing shallow saline water-table behavior in salinity-affected irrigated regions. Designed for feasibility-stage project planning, the model may be used to develop economically optimal irrigation and drainage strategies for long-term regional management. Incorporation of uncertainty due to regional-scale physical parameter variability placed the optimal management problem in a stochastic setting. Management objective and constraint functions developed relate long-term spatial random distributions of water-table depth, aquifer salinity, soil-water salinity and other variables to economic net benefits from crop production. The stochastic optimization problem was solved by response surface methodology via Monte Carlo simulation and by a stochastic quasi-gradient technique. An application to a hypothetical system representative of conditions in the western San Joaquin Valley of California revealed the merits of the model in providing decision makers with a set of alternative strategies for possible implementation in a regional project.
