Abstract

This paper presents sediment dynamics in the Mekong estuaries and coastal zone using the Delft3D-4 modeling system. The results show that the Mekong and Bassac River provide a large amount of sediment (more than 90%) that is deposited in front of the mouths due to coastal processes in the flood season. The sediment transport along the coast changes with the monsoon and is dominantly south-west directed during the north-east monsoon, especially in November, December and January.
