Tidal and Sediment Simulation Study in the Gangzhong Harbour District of Weifang Port
This study investigates the tidal dynamics and channel siltation issues in the Gangzhong harbour district of Weifang port.It begins with an overview of the geographical characteristics and current channel conditions of Weifang port,followed by the establishment of a two-dimensional tidal and sediment mathematical model,calculated using the Mike21 FM module.Model validation indicates that the simulation results match well with the measured data,meeting the technical specifications.The results indicate that after project implementation,the flood and ebb tidal states in the port area remain basically consistent,with flow velocity gradually decreasing within the port.The maximum transverse current within the channel is influenced by the sand barrier,with the highest velocity at the port entrance.Sedimentation analysis shows that the maximum sedimentation peak occurs approximately 1 km outside the port entrance,with a maximum annual sedimentation thickness of 1.84 m,and an average annual sediment thickness of 0.10m within the harbor basin.Under strong wind conditions,sedimentation thickness increases in both the channel and harbor basin.This study provides a scientific basis for the development of the Gangzhong harbour district of Weifang port and offers valuable insights for channel maintenance and sand control measures in similar ports.
