In recent years, after renovation policy launched by the Vietnamese government, the economy of Kien An – Do Son, Hai Phong coastal zone in Northern Vietnam has quickly changed with high income and fast economical grow rate. Unfortunately, together with the fast economical development, the environment in many areas has been severely damaged. In addition, the climate change also increases geohazards especially flooding, storms surges, sea level rise, salt intrusion ... causing the losses of human lives and properties to people living in this very sensitive zone. Basing on the results obtained in the recent site investigation and laboratory tests, the main geohazards recorded such as coastal and river bank erosion, salt intrusion… are studied and disscused in detail from geotechnical point of view. The results of this study help to propose the suitable longterm remedial measures to mitigate the hazards for the sustainable development of this coastal zone. |
