The present study conducts a series of hindcast simulations for Typhoon Haiyan storm surges and waves using a coupled model of surge and wave (SuWAT) with changing typhoon radius in 30 km, 40 km, 50 km, 70 km, 80 km, and satellite observation as well as wind velocity limit for the wave dependent drag coefficient. The hindcast results indicate that the radiuses of 50 km and 70 km are reasonable to calculate the typhoon Haiyan storm surges along Leyte Gulf. The 30 m/s wind speed limit for the wave dependent drag coefficient is acceptable in comparison with the field survey results. Further study, which includes inundation modeling, is required to assess the Haiyan storm surges more accurate.
