A groundwater management tool for solving the pumping cost minimization problem for the Tahtali watershed (Izmir-Turkey) using hybrid HS-Solver optimization algorithm

► A linked simulation-optimization model is proposed to search alternative well field locations with minimum cost of pumping. ► How to use a hybrid optimization approach in groundwater management is presented. ► Applicability of the proposed procedure is tested in a case study. ► Model robustness is evaluated by performing a sensitivity analysis for different optimization parameters.
