SYNOPSIS

The consequences resulting from dam failure usually lead to major damages, including loss of life and property destruction. To mitigate and manage the threats of dam break, it is essential to appreciate the characteristics of potential flood disaster in a realistic manner. In this study, an approach based on the integration of 2D hydrodynamic modelling and geospatial technologies is used to pre-plan the coordination of necessary actions by the dam owner and the responsible local, state, and/or federal officials to provide for timely notification, warning and evacuation in the event of an emergency. In addition, the preparation of EAP is to reduce the risk of loss of life and property damage, particularly in the downstream areas of a dam and the river basin, resulting from an emergency situation. This 2D flow simulation model with geospatial application is used to simulate flood hydrodynamic behaviour using the extracted geometric information from a digital elevation model. Flow simulation of the dam break was performed and results were analysed using spatial analyst and mapped. Finally, a flood hazard map and flood evacuation map consisting of the inundation area, flood depth, flood flow velocity, flood flow arriving time and flood inundation duration were created in GIS environment. According to these maps, the potential failure of the dam would usually place a large number of people in danger. This study has shown that the application of GIS techniques in integrating with flow simulation modelling can significantly reduce the time and resources required to forecast potential dam break flood hazard. This can play a crucial role in improving both flood disaster management and land use planning downstream of dams.
