한국의 폭풍해일 재해 저감 연구

Abstract

There are two major methods in mitigating the hazard caused by storm surges: one by short-term prediction of impending extreme water level using available information to take immediate actions to reduce risk such as evacuation, rescue, etc. and the other by long-term statistical prediction of extreme water level as a basic information to take long-term and rather fundamental counter-measure to reduce coastal hazard. Both methods require accurate information on meteorological forcing and field observation data from water level observation network.After significant damages caused by Typhoon Maemi for the southern coastal area of Korea in 2003, Korean government has been taking actions to counter-measure to reduce storm surge disaster along the coast of Korea. The on-going research activities on storm surge disaster prevention in Korea are introduced for the following three areas: Water level observation system, Storm surge prediction system and Estimation of design wave height and water level.
