摘要：Floods can be extremely harmful for the welfare of societies regardless if they are natural or caused by humans. The Mediterranean region has experienced an increase in flash floods frequency and severity. The suddenness and episodic nature of these type of floods makes it more difficult to predict them compared to river floods. In this study, a map was developed in regard to the flood susceptibility of Zakynthos Island with the use a multi-criteria decision analysis. This analysis utilized six factors: a) flow accumulation, b) land use, c) slope, d) rainfall intensity, e) geology and f) elevation. Each factor had a different weight based on their importance in regard to flash floods. The analysis was run in GIS. To validate the developed susceptibility map, the locations of the recorded past floods on the island were utilized. The end product was a validated flood susceptibility map. This map can help the Civil Protection Authority of Zakynthos Island to mitigate communities’ susceptibility to flash floods.
