Abstract

The 250,000 dwt Navigation Channel of the Panjin Port is planned to be constructed. Three layout schemes are designed in the project. The hydrodynamics, sediment transport and channel siltation before and after the project under different layout schemes are calculated by numerical model. The results show that for three schemes, the sediment concentration within the waterway show decrease after the construction of the waterway. The annual back-silting thickness is large near the port and small in the offshore area. The total deposition amount and average thickness of scheme 1 is larger than that of scheme 2. In addition, the channel of scheme 3 shows a significant sedimentation at the end of the channel because of the turn of the axis.
