Project's information

Project's title To study Tectonic structure and Geodynamics of Mekong delta in order to have a better adaptation and mitigation of natural hazards of sea level rise
Research hosting institution Institute of Marine Geology and Geophysics
Project leader’s name Dr. Phung Van Phach
Project duration 01/01/2010 - 01/01/2011
Project’s budget 400 000 000 VND
Classify Excellent
Goal and objectives of the project
  • To clarify the basement structure and the current tectonic-geodynamic activities of the Mekong delta region.
  • To clarify the role as well as influence of the tectonic movement to the Mekong delta caused by sea level rise.
  • To direct the strategic policy on the optimal territorry use in order to adapt to the change of environmental condition of the region.
Main results
  • Sientific significance: The results of the Project are qualitative, helping people to have a better understanding of the nature of the Mekong delta as well as its development in Holocene-Recent period. As a result, it is able to give out the appropriate forcast for different subjects in the climate change condition.
  • Application significance: scientific evaluation of the the history of sea-level change and its tendency in  the future, serving basis for strugling with the risks of sea level rise.

Novelty and actuality and scientific meaningfulness of the results
  • The notches in the limestone hills + 4.5 m of the Ha Tien area must be formed at  MIS 5e period, about 130,115 years BP.
  • The sedimentation rate at the foot of the Mekong delta is approximately equal rate of sea level rise during last 100 years; this is the reason why the out boundary of the delta remained unchanged during this period.
