Abstract
It is difficult to provide effective measures for disaster prevention as the current monitoring system to prevent disasters taking place in national infrastructure facilities like reservoirs still remains at the level of data accumulation. In this study, the technical specifications of the specialized monitoring system for the failure modes of Korean reservoirs (fill dams) are proposed and the monitoring criteria for the early warning system of reservoirs are provided, in order to expand the application of the accumulated data of the disaster prevention system and introduce the Ubiquitous Sensing Network to the present monitoring work.
