Impacts of sea level rise scenarios on flood water levels in Dong Thap Muoi region, Mekong river delta

Abstract

     Dong Thap Muoi region is a lowerest part of Mekong Delta in Vietnam, flood is annual occured during wet season, and its impat is causes a large inundation area in this region every year. Moreover, in context of sea level rise impacts lead to flood water levels and flood inundation time is more increase, the flood drainage is also more difficult. These problems are to influence on water resources, environment, ecosystems, socio-economic activities of people, and especially impacted directly to agricultural production. Therefore, purpose of study is to assess the change flood water levels and flood inundation time in Dong Thap Muoi region under impact of sea level rising of 20cm and 50cm scenarios. The results of study could be useful to forecast of water level floods change and inundation time, which can help the manager to proposal of flood control solutions in order to mitigate the flood damage and to exploit the flood benefits as well as satisfy immediate and long-term requirements in flood management in Dong Thap Muoi region.
