Integrated multi-criteria flood vulnerability approach using fuzzy TOPSIS and Delphi technique

摘要: Abstract. This study aims to develop a new procedure that combines multi-criteria spatial vulnerability analysis with the traditional linear probabilistic risk approach. approach is named integrated fuzzy flood assessment because it watershed-based framework stream-based analysis. The Delphi technique and pressure-state-impact-response are introduced objectively select evaluation criteria, TOPSIS proposed address uncertainty of weights all criteria crisp input data units. ArcGIS used represent results criteria. applied south Han River basin in South Korea. As result, ranking was derived characteristics units were compared. can be conduct prefeasibility for mitigation projects when various stakeholders should included.
