ABSTRACT

To compute the alluvium transport, we use a current model based on a 2D finite-difference grid and a sediment transport model. The first one gives the velocity distribution on the surface of water body and in the case of transient analysis, the velocity distribution is computed at each computational time step. This velocity distribution will be taken as the input for the second model. There are two important problems solved in this research: using moving boundary to get more correct results and testing the results by remote sensing. The models were used to compute the alluvium transport in Ca Mau coastal zone. The resonableness in the transport trend of alluvium shows that those models are confident.
