Waves and storm surges during the tropical typhoons are ones of the most severe natural disasters, which significantly affect on coastal structures in coastal area. Especially, when typhoon comes during high tidal level, the combination of waves, surges and tides is the cause of coastal inundation and erosion, resulting in destroying coastal constructions. Technically, coastal inundation caused by typhoon depends on the coastal topography (land and underwater), tides, storm surge and wave setup. Therefore, the effects of tides, storm surge and waves are necessary to taken into account to forecasting inundation model. In addition, the coastal topography needs to have very high resolution and to consider the sea dyke system. A coupled model of surge, wave and tide (SuWAT) developed by Kyoto University, Japan has been applied in forecasting storm surge at the Vietnam National Center for Hydro–meteorological Forecasting. In this study, the results of simulated inundation along the coastal area of Thai Binh Province during the Damrey (9/2005) typhoon are presented in wich several scenarios are performed. Based on this study, SuWAT model could be further researched on warning and forecasting inundation for coastal areas of Vietnam.
