climate change, natural disasters has become more complex, especially storms, accompanied by sea level rise, which caused inundation in coastal area Storm surges can cause inundation to coastal areas and can cause dike break, especially if storms occur during high tides Therefore, studying, calculation and forecasting on the extreme water level during storm at coastal locations and assessment of inundated risk by storm is very important for finding the solutions and positive measures to prevent and mitigate damages Storm surge is a dangerous natural phenomenon, which caused a lot of damage to people and property In Vietnam, the highest water level has recorded as 3.6 m in 1989 by Dan storm Storm surge is particularly dangerous when the storm occurs at the same time with spring tides and in this situation, total water level rising combined with strong wave can cause dike breaks and wave overtopping and also cause heavy damages to people and property In Vietnam in general and Con Dao islands in particular, although there are a lot of studies of sea level fluctuations in storm, but most of which focus on water level fluctuations on a large scale The fluctuations of water level in coastal locations and inundated risk have not been interested adequately yet, especially when assessing the inundated risk of coastal area Therefore, studying of extreme water levels in storm, in consideration of tides, storm surges, waves and inundated risk to coastal area takes a great scientific meaning The result of study will contribute to mitigate the unfavourable impact of storm surges, serve for protection and maintenance, upgrading of coastal structures, shoreline protection, requirement for socio-economic development, environmental protection and sustainable development Study objectives To assess situation of inundation due to storm surge for Con Dao islands 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 06/12/2007 01:00 06/12/2007
