South Sumatra Province is one of the provinces in Indonesia with high revenue amongst other provinces. However, they have an issue with their logistics and transportation effectiveness. Their major ports are in the river area which limits the vessel size. Boom Baru Port, for an instance, is a major located in Palembang, the Capital of South Sumatra Province. This port is the Musi river with the draft only about -6 m from the lowest water spring (LWS). A plan has been made to develop a major port in the coastal area. Tanjung Carat is planned as an alternative location for a major port in Indonesia. However, this location is in the estuary area. Sedimentation become one of the major threads for the port development plan in this location. Furthermore, only a few studies that available in the public domain for the sedimentation process in this location. Tanjung Carat is an estuary area for a few major rivers in South Sumatra, such as Musi Banyuasin and Musi. The upstream of the major rivers are mining or agricultural area. Therefore, sedimentation is massive in this area. As an estuary, the tidal forcing in this area is complex. The tidal asymmetry that has been discussed in many papers plays an important role in the complexity of the tidal hydrodynamic in this area. Tanjung Carat estuary is also connected to the Bangka Strait which makes the tidal hydrodynamic in this area even more complex. Using Delft 3D, this paper modelled the hydrodynamic process in Tanjung Carat Estuary. The analysis also includes the wave-induced current process in this area. Therefore, we could see which major forces that dictate the sedimentation process in this area.
