<p align="justify">Indonesian Coal production is one of the 10 largest world producers. The largest coal resource is South Sumatera however its production is defeated by South Kalimantan and its export is left behind of East Kalimantan. One of the reasons is lack of infrastructure. Nowadays, coal transport from Lahat and Muara Enim Regency, the largest coal producers in South Sumatera, mostly through the roadway. As a result, the road is badly damaged and the residents is harmed. Inland waterway by Musi River and its tributaries can be one of the alternative solution. Shipping line in Musi River today is only available to port near Palembang. The objective of this study is to design horizontal and vertical profile of inland waterway for coal transport in Musi River, South Sumatera. Musi Canal is planned thru 170 km from the estuary. Terminal location is determined by considering of these things: far from the settlement, near to the coal resources, near to tributary which hopefully can be shipping line too, and mostly straight river line. Hydrological calculation using rainfall data from 3 rainfall posts. Hydraulics of water flow is modeled using HEC-RAS (Hydrologic Engineering Center-River Analysis System) 5.0.3. Flood discharge with return period 50 years is used to know the clearance under the Ampera Bridge for determining the ship. The ship used in this study is self-propelled barge with length 69,8 m, width 14 m, and draft 3,3 m. The canal design is refer to Waterways Guidelines, 2011. Minimum waterway profile required is bending radius 275,6 m, width 50 m, depth –4,5 m. The width and bending radius of river is qualified so the horizontal canal profile is not change. The depth of 70 stations are not qualified so they need to be dredged up to -4,5m. Slope stability because of dredging and embankment is modeled using Plaxis 8.5 2D. The results show that the safety factor of all stations are qualified to the minimum value.<p align="justify">
