Typhoon Wave Modelling for Viet Nam Central Region
- 22 Downloads
Coastal zone plays a very important role in Vietnam socio-economic development, especially with the central region. However, the coastal line in Vietnam central region has been changed seriously. It becomes more complicated in recent years when shoreline erosion has occurred in many localtities. The consequence of this natural phenomenon has affected significantly to these area. The sea level rise and typhoon wave are considered as the main causes of unexpected phenomenon. With the aim of mitigating the impact of typhoon wave to coastal line in central Vietnam, this study is realised. By using Mike softwave family of DHI for coastal zone from Binh Dinh to Binh Thuan, Viet Nam, the result will allow not only us to understand, predict and design mitigation measures to combat the effects of these typhoons, it will also allow us to develop a methodology to be used elsewhere on the Viet Nam coast. The model is calibrated and validated versus water level data of Quy Nhon station and of two other temporary stations in central area, also compared to WAVEWATCH III model result with high performance. Result from four different typhoon scenario (from level 6 to level 12) are analysed to provide basic information about the wave situation then estimating their impact to study area.
