URBAN FLOOD HAZARD ASSESSMENT TO FLOOD USING GIS BASED AHP APPROACH

Abstract

Floods in urban area are one of the most frequently occurring and widespread
disasters affecting the urban morphologyworldwide (Zhongming eted. 2012). The
evidence írom across the world shows that in the last decades the frequency and
severity ofurban flooding has increased significantly (Miller -Huntchins 2017).
Urban flooding could be initiated by either natural activity like heavy rainfall
intensity or humán activities such as urban encroachment along river banks or
flood plains, poor urban infrastructure, lack of a proper drainage system,
deforestation and interference in natural waterways (Huang et al. 2018; Song et
cd. 2019, Adekola - Lamond 2018).
