Drinking water wells close to coastal areas getting contaminated groundwater can be minimized by developing an optimal pumping strategy of pumping, both in space and time. Groundwater management problems are solved in a more efficient way by combining simulation and optimization in a single framework. Simulation–optimization-based development of the groundwater system is required, to reduce the risk of pumping contaminated water. This paper presents a study where a simulation–optimization model based on a 3D groundwater model and genetic algorithm was developed and applied to a case study. A 3D groundwater model has been developed, for the case study system of South Chennai Aquifer System where significant amount of groundwater is being pumped for domestic consumption. The calibrated groundwater model was used as the simulation component in the linked simulation–optimization model. The combined model was then used to identify the optimum pumping strategy.
