해면관측자료로 부터 산정한 해일고의 비교

Abstract

By definition, storm surge is the difference between the observed and the predicted sea surface level. However, there are no rules or guidance to 1) what kind of the observed data should be chosen (record interval), 2) how to handle the observed data (smoothing methods), and 3) what is the standard method to predict the tides, i.e., how many the harmonic constants should be used in the prediction. In this paper, we tried to compare how much the maximum storm surge height can differ by above questions. During all typhoon events after 2003 two sets of tidal records (1-minute and 1-hour intervals) from National Oceanographic Research Institute (NORI) in Korea were used to analyze the maximum surge heights
