Abstract
Advances in computer power and mathematical optimization procedures can improve planning and developing sustainable irrigation systems. Simulation and optimization models can help plm1 groundwater and conjunctive use strategies to best achieve management goals while satisfying mm1agement a11d physical constraints. Simulation/optimization models that couple calibrated flow and transport simulation models with optimization algorithms can help design the best water management strategies. Mm1agers can be relatively sure that the groundwater system will respond acceptably when appropriate procedures are employed to develop the water management strategies. Presented case studies illustrate situations in which developed strategies simultaneously address conflicting management goals such as: maximizing sustainable groundwater extraction or conjunctive use versus: minimizing spread or degree of contamination, maintaining adequate artesian flow at springs, or maintaining adequate flow in rivers. Another case illustrates how time-varying future irrigation water needs can be best satisfied by combining groundwater and surface water resources--while assuring adequate saturated aquifer thickness for drought protection and maintaining sufficient river flow for navigation and commerce.
