Abstract

The propagation and associated run-up process of tsunami are numerically investigated in this study. A transoceanic propagation model is first used to simulate the distant propagation of tsunamis. An inundation model is then employed to simulate the subsequent run-up process near coastline. A case study is done for the 1960 Chilean tsunami. A detailed maximum inundation map at Hilo Bay is obtained and compared with field observation and other numerical model predictions. A very reasonable agreement is observed.

지진해일의 전파와 이에 부수되는 처오름과정에 관한 수치해석에 관하여 연구하였다. 먼저, 대양을 가로질러 전파하는 지진해일을 모의하는 전파모형과 해안선 근처에서의 처오름과정을 모의하는 범람모형에 대하여 서술하였다. 수치모형을 1760년 칠레 지진해일에 적용하여 지진해일의 전파과정과 하와이 힐로만에서의 범람을 수치해석하였다. 철로만의 최대범람구역을 결정하여 현장관측자료 및 다른 수치해석 예측과 비교하여 매우 만족할만한 결과를 얻었다.
