ABSTRACT

Due to unusual precipitation or flood, the rivers located at the downstream of reservoir may influence the safety of the people living near the river. This study provides a guideline for the local government officials, managers and residents to prepare against disasters by analyzing the change in water level (rise) especially when PMF occurs. The study discovers the relationship between the overflowing water level from the reservoir and change in downstream water level and use it as an indicator for responding to disasters. The attention level(“Blue”), the early emergency management stage, is determined as from the issuance of a special weather alert to the water level that comes at 10% of the planned overflowing water level due to flood in the reservoir spillway. This study also suggests that the caution level(“Yellow”) should be set as a water level that comes at 10 to 100% of the planned level in the reservoir spillway due to a massive flood. The results of this study are expected to contribute to implementing an effective disaster response system in Korea.
