Vulnerability of Flood Hazard in Selected Ayeyarwady Delta Region, Myanmar

Abstract

Flood disaster is a function of both natural hazard and vulnerable environs. It is needed to identify the flood hazard area for proper management and mitigation damage. River flood occurs because of heavy rainfall and geomorphology. In this study, Flood vulnerable areas for different return period flood are assessed by using Hydrologic Engineering Center's River Analysis System (HEC-RAS) model, GIS and Remote Sensing technique. Flood vulnerability analysis is carried out by overlaying the land use map and flood hazard map generated by the hydraulic model. GIS can be used to create interactive map overlays, which clearly illustrate which areas of a community are in danger of flooding. The main objective is to assess the flood vulnerable areas. Special attention of the concerned area on this disaster should be done to minimize loss from damage.
