Comparison between simulation of storm surge invoked by typhoon “Yolanda” and field results

Abstract

The catastrophic typhoon “Yolanda” on Nov. 2013 invoked storm surge in the coastal area of the Philippines. The storm surge made the coastal regions to the devastation and maximum water height reached 5m in the Tacloban area. This paper presents the comparison between storm surge simulated results from atmospheric - storm surge- wave- tide coupled model and the observation measured by The 2013 Philippines Storm Surge Joint Survey Group headed up by Prof T. Shibayama. In this study, the TC-Bogus scheme is used in order to simulate accurate typhoon. The simulated storm surge results reached almost 5m in the Tacloban area. The coupled model including TC-Bogus scheme gives accurate simulations for estimating storm surge.
