Mega cities of South East Asia have been remarkable urban sprawl and dynamic change of the Natural and Human environment. Risk against natural hazard has been increasing in these cities and suburban area is also becoming more vulnerable against natural hazard. One of the huge city is Hanoi capital where is located on the alluvial plain in the great delta. The Red river Delta of Northern Part of Vietnam has been remarkable changed in the Late Quaternary Period and the these alluvial plain along the Red River has been constructed and formed for fluvial geomorphology affected by great response from continuous sea level change under the global climatic change in the Holocene period. Sea level change and their influences on the tropical delta and sub-tropical delta are multiple diversities in South East Asia. In this project, considering for each climatic specific features and near future global warming, delta and sea linkage were studied and researched assessment from response of climatic change. We tried to describe paleo-geography in the delta.
