摘要：Musi river is the largest river in Palembang with a length of more than 750 kilometers. The sedimentation in the Musi river is commonly existed due to the high level meeting of velocity between the Musi river and the ocean in the Bangka Strait. The silting condition of Musi river is getting more severe due to the sludge growth that reach about 40 cm per month. In fact, the volume of sludge could reach 2.5 million m3. There are 13 silted points along the river shipping channel from the Boom Baru port to Bangka Strait. Four points are vulnerable due to the siltings reach up to 4 m. This research was conducted by using the approach of software models MIKE 21 Flow Models. The results obtained from this study are the greatest speed direction occurred, elevation of the outer surface and total depth of water will contribute and effect to the free area for ships to perform well and safe movement. The other side will effect of the amount of sedimentation and the aquatic environment of the swamp area.
