Outline of Final Research Achievements

This study aims at predictions of maximum possible storm surges. To improve the accuracy of the storm surge forecast simulation, it is necessary to correctly evaluate the wind drag coefficient, which represents the shear stress acting on the sea surface from the wind. However, it is uncertain whether the bulk formula of the wind drag coefficient based on the past typhoons is suitable for the storm surge caused by a strong typhoon. From this situation, we require the
observation data of many typhoons generated by global warming.
Data of current, wave, wind were under strong typhoons were observed under in Amitori Bay of Iriomote Island. Next, we added the input function of meteorological field into T-STOC so as to calculate storm surge. As a result, T-STOC with the function of meteorological field was confirmed to reproduce the maxi-mum value of storm surge deviation, and T-STOC is said to be able to simulate storm surge inundation.

Academic Significance and Societal Importance of the Research Achievements

本研究によって,温暖化時に三大湾に来襲すると予測されている強大台風に相当する台風下の流速などのデータを取得した.これによって,信頼性の高い高潮・高波・浸水を予測することができた.この結果は,計画規模を上回る高潮に対するハード面の整備を議論する際,基礎検討の一助として活用できると考えられる.
