Abstract
Agricultural activities of western Jeju island has suffered from saltwater intrusion seasonally. Objectives of this study are to prove the occurrence of saltwater intrusion in the coastal aquifer and to consider a management plan using MODFLOW-family code SEAWAT model. Model results show that the saltwater-freshwater interface intrudes inland only a few meters and that upconing phenomenon is rather the cause of the severe disaster of the agricultural water contamination. This study selected Gosan area as a representative site to estimate optimal groundwater development regulation against upconing by seasonal pumping for agriculture. The suggested optimal groundwater development estimation method considers the groundwater levels of representative monitoring wells for regulatory alarms.
