Abstract
AbstractGroundwater contamination is one of the most serious environmental problems in many parts of the world. For remediation of dissolved phase contaminants in groundwater, a pump-and-treat method is found to be a successful remediation technique. Developing an efficient and robust design to solve groundwater pollution remediation problems using a pump-and-treat method is very important because of the large construction and operating costs involved. In this study, an attempt is made to develop a coupled simulation-optimization model based on the finite-element method (FEM) and an evolutionary approach of an elitist genetic algorithm (EGA) for the optimal design of groundwater remediation by pump and treat. The model couples an EGA, a global search technique, with FEM for coupled flow, and a solute transport model to optimize the pump and treat groundwater pollution problems. The simulation-optimization model is used to optimize the remediation of a large-field unconfined aquifer polluted with total dis...
