Abstract
A sensor-based landslide early warning system in landslide highly-prone site of urban areas as a part of integrated prevention system for sediment-related disasters was suggested. The system mainly consisted of sensors, network system, and monitoring system and it had been partly revised for the improvement of its effectiveness through 3-year test-bed monitoring. The magnitude of sediment disaster (SDM) considering physical scale of the disaster and damage level was introduced for deciding the appropriate location of the system installation. The case study for Yongin-si, Republic of Korea, showed the 44 of total 1013 debris flow-hazard watersheds were estimated as the first level of SDM, the most risky area, and one of the 44 watersheds was finally selected as the system location through field investigations. In the selected 10 ha watershed, pilot construction of the system was conduct as a first step of its field application. It was hoped that the suggested system can effectively mitigate human damage by sediment-related disasters through sending landslide early warning information to residents at a landslide highly risky area directly.
