INFLUENCE OF COASTAL RECLAMATION IN ZHANGZHOU PORT ON COASTAL EVOLUTION OF NEIGHBORING SEA AREA

摘要

Based on the accretion of sediment in harbor areas because of coastal reclamation nearby, the paper analyzes the landform, hydrodynamic factors, sediment and coastal evolution. According to topographic varieties before and after construction, the amount of the coastal backfill and the sediment transport data of the Jiulongjiang River are studied, and the influence on coastal evolution and siltation in the harbor are analyzed. The research shows after the coastal reclamation, the sediment deposition in the nearby harbor is due to natural silt deposition, beach accretion and muddy current caused by coastal backfill. When the coastal reclamation is finished, the new coast will reach a new balance gradually, and the deposition in the dock will also return to the natural level gradually.
