Pumping optimization in saltwater-intruded coastal aquifers

This paper investigates the hydraulic issues of pumping well optimization i n saltwater-intruded coastal aquifers. The well field includes freshwater o utflow, pumping wells, and a recharge canal. The objective is to maximize t he total pumping rate subject to the constraint of no intrusion of the salt water front into the wells. Analytical solutions are presented for one-well , two-well, and one-well-with-recharge-canal problems. For problems involvi ng multiple pumping wells, a structured messy genetic algorithm is used to search for the optimal solution.
