Characteristics of Storm Surges and Stormy Waves Induced by Typhoon Haiyan around Leyte and Samar

Abstract

This paper aims to overview the hydrodynamic characteristics of storm surges and waves induced by Typhoon Haiyan around Leyte and Samar, Philippines, especially based on the results of the post disaster joint survey of PICE and JSCE. A number of local residents remained along the coast when inundation started and, based on intensive interviews of those local residents, the survey team obtained information of not only the heights of inundation and run-up, but also other hydrodynamic features such as timings and durations of inundations, flow directions and the level of surface water fluctuations. Comparisons of these findings of the disaster survey and numerical analysis clearly indicated that the wind-induced stormy waves had significant impact on inundations especially along the east coast of Leyte and Eastern Samar.
