Optimal location of cutoff walls for seawater intrusion

Abstract In this paper, the simulation–optimization method is used to study optimal location of cutoff walls for seawater intrusion. The optimization model based on minimizing chlorine concentration two water sources after 50 years. order reduce computational complexity, a Kriging surrogate simulation coupled with model. Finally, hypothetical case evaluate accuracy and performance results show that outputs variable density groundwater same wall design fit well, average relative error only 2.2% which proves it feasible apply problem. By solving model, minimizes sum years obtained. This provides stable reliable site selection future projects intended prevent control
