| Abstract;Monitoring and modeling of seawater intrusion into coastal aquifers are indispensable for successful conservation and proper management of fresh groundwater resources in coastal areas. In this study, a field survey was firstly conducted to investigate the current situation of seawater intrusion in Yoron Island, Japan. Secondly, a numerical approach based on the concept of the sharp interface approximation between freshwater and seawater was applied in the analysis of field data. In the numerical calculation, a single tank model for estimating groundwater recharge from land surface was coupled with the sharp interface approach. The coupled numerical approach was used to evaluate the influence of rainfall events on the seawater intrusion. The results show that the calculated groundwater level and the position of the seawater intrusion are in good agreement with the measured values at the observation wells and boreholes on the island.
