Numerical Simulation for Estimating of Sediment Transport due Layouts of Port

The need for a new and improved fisheries port has significantly increased in the Bireuen District of Aceh, particularly in Peudada due to several factors presented in this paper. During this time the fishing port used by the communities located in the river channel makes it difficult for the fishermen to get into the port area due to the shallowness of the mouth of the estuary. Port master plan study is required to examine several possible locations for the proposed port. In planning the hydro-oceanographic aspects of the port is an essential requirement to determine the layout of a port. Several factors that need to be reviewed relating to the layout of the ports include sedimentation, waves, and currents. These factors affect the movement of the ship, tranquility waves in the port basin, and for the maintenance dredging of the harbor due to sedimentation. This study is aimed at estimating the best layout of the port basin between two scenarios due to the sedimentation process, waves propagation, and currents. The software used in this study is Delft3D developed by Deltares. The program can simulate waves, currents and sediment transport in coastal areas by using schematized grids. The simulation was performed under two scenarios port layout using three dominant wind direction influencing wave generation, i.e., Northwest, North, and Northeast. All two scenarios modeled by changing the direction of opening the mouth of the harbor. After one year, both scenarios simulation has created a new bathymetry map to select the best port layout based on smallest sedimentation volume.
