ADCIRC Analysis of Super Typhoon Haiyan in Leyte Gulf

DescriptionTyphoon Haiyan made landfall as a Category 5 storm on the eastern coast of the Philippines on November 8, 2013. Characterized by very low central pressures, fast forward moving speed, and sustained wind speeds higher than 150 miles per hour, Haiyan was one of the most devastating Typhoons to make landfall in the Philippines, displacing 4.1 million people, killing more than 6000 and leaving 1800 unaccounted for. The combination of the unique sea floor topography in Leyte Gulf and the Philippines Trench paired with such a powerful storm resulted in widespread destruction of the areas surrounding Leyte bay and more generally, in the path of Haiyan. The Leyte Gulf is defined by primarily shallow water that quickly drops off at the open ocean boundary into the Philippines Trench. This combination of underwater features paired with the unique characteristics of Haiyan allowed for extensive inundation of the surrounding area. This poster details the simulation of storm surge and tidal interactions of Typhoon Haiyan in the Island chain surrounding Leyte Gulf. All computations were done on Lonestar using the Advanced Circulation (ADCIRC) unstructured grid hydrodynamic model.
