【 摘 要 】

This paper is a study of the application of material sedimentation on a river water dam that does not need to be streamed again. The problem will be shown in three forms of occurrence that is, while the water is flat, curved and steep down. The finite element method is used to solve the problem in the form of Darcy equation in two dimensional case. The solution is performed by using the COMSOL Multiphysics 5.2 for the flow phenomenon. The results obtained will be more of the material sedimented in flat water conditions, but for the water conditions curved and steep to the bottom water that has not yet experienced more sedimentation is discarded.
