  • Artificial injection of surplus surface water during wet seasons and recovery is one of possible solutions for conjunctive uses of surface water and groundwater. The methodology is especially attractive for regions of monsoon type weather. In this work a simulation-optimization model is developed to identify an optimal injection system to sustain an over-exploiting freshwater pumping well. The injection well is to be operated during wet seasons only while the pumping well is to be operated throughout an entire year. The objective function is the minimization of injected volume of freshwater. Saltwater intrusion and dry wells are considered as constraints. An example application is made on a small hypothetical island with poor hydrogeologic conditions. The optimization model is successful in determining optimal injection locations and rates for various cases.
