Abstract
Tsunami simulator “T-STOC” has released as an analysis program to calculate tsunami behavior from ocean to coastal area integrally. However, T-STOC does not support a storm surge simulation because wind speed and air pressure cannot be set on free surface boundary. In this study, we added the input function of meteorological field into T-STOC so as to calculate storm surge. From the test calculation results with the meteorological field, we confirmed the validation of domain division setting and nesting method. Next, we calculated storm surge caused by previous typhoon in Seto Inland Sea, and compared the numerical results with the field observation ones in terms of storm surge deviation. As a result, T-STOC with the function of meteorological field was confirmed to reproduce the maximum value of storm surge deviation, and T-STOC is said to be able to simulate storm surge inundation. Furthermore, the influence of the number of vertical layer on storm surge analysis was also examined in this study.
