Abstract |
Sea level rise due to global warming causes seawater intrusion into aquifers in coastal areas. Seawater intrusion vulnerability index was developed using PSR (Pressure, State, Response) model and analysis hierarchy process (AHP). Coastal regions in Korea, Gangwon-do Sokcho-si, Incheon-si Ganghwa-gun, Chungcheongnam-do Taean-gun, Jeollanam-do Yeosu-si, Jindo-gun were chosen and 14 indicators were selected by considering the humanities, economic, social, environmental aspects. Re-scaling method was used for the standardization of indices and questionnaire survey was performed to calculate weight values for each index. The results showed that Yeosu-si was selected as the most vulnerable region to seawater intrusion. The seawater intrusion index developed in this research can be used to analyze the vulnerable regions to seawater intrusion and to establish a policy to minimize the seawater intrusion problems in coastal regions. |
