Abstract
According to the Fourth Assessment Report of the IPCC, due to the climate change, it is assumed that the flood damages such as typhoon will be increased at lowland area.In order to decrease storm and flood damages, it is important to unify the measures over landuse, environmental plan, and traffic environment. In this research, we focused on the Hai-Hau coast that is a downstream of Red-River,Vietnam. Around the Hai-hau coast, vast lowland area are distributed. So, in this research, it is estimated that the influence to the characteristics of landcover caused by the river flood and beach erosion.The result of this study, we generated the geographic information for water-related disaster, and considered the relation with present condition of landuse.
