丹东海洋红海域水动力泥沙环境分析

摘要

基于现场实测水文泥沙资料，对丹东海洋红海域的水文泥沙环境进行了研究。研究结果表明：该海域近岸波浪潮流动力不强，正常天气条件下水体含沙量小、潮流输沙能力不强、泥沙来源少、具备建设大型港口的基本条件。由于该海区属于粉沙质海岸，航道泥沙骤淤将是建港中要考虑的重点问题。%Based on observed field data of hydrology and sediment, the hydrodynamic sediment conditions of Haiyanghong sea area in Dandong were studied. The results show that the force of tidal current and wave is not strong in this area. The suspended sediment concentration is small under normal weather conditions. The sediment transport capacity by tidal current is not strong. The sediment resource is little, and the seabed is stable for a long time. However, as this sea area belongs to silt⁃sandy coast, the sudden sedimentation of navigational channel will be a key problem to be considered.
