ABSTRACT

The current approach to reservoir safety management in South Korea mainly focuses on reducing failure rates. This approach may help minimizing failure incidents, but fail to efficiently manage risk to life and property. To minimize the losses from potential incidents in reservoirs, the paradigm shift to the social risk management would be needed. For a more effective reservoir management from the perspective of social risk management, an accurate prediction and illustration of the consequences from the failures is critical, such as spatial mapping of inundation hazards due to reservoir failure. In this study, we developed the mapping tool illustrating dam-break inundation hazards using spatial data to support the new paradigm. The inundation hazard maps were found applicable in practice according to the comparation with the historic failures. Its practical effectiveness was also confirmed because it took only several hours to create hazard maps for hundreds of reservoirs.
