摘要：
The aim of this paper is to clarify the basic mechanism of sediment transport in Yangon River, Myanmar. Two dimensional numerical model is used to predict the water flow and sediment transport. The models for the flow and sediment transport are described in this paper. The water depth, velocity, sediment concentration and the bed level change were calculated for 4 cases near the "Inner Bar" area. It was found that the tidal current has a great influence on the sediment transport and the sediment concentration is higher at the ebb tide in both spring and neap tide condition. The flow velocities and the sediment concentration are verified against field data of Nelson (2000).
