摘要
悬浮泥沙是重要的水质参数之一,其大小直接影响水体透明度、浑浊度、水色等光学性质及水生生态条件,其含量及其动态变化对该区的水下地貌的发展及冲淤变化、港口建设等具有非常重要的影响。本文利用ECOMSED模型,对辽宁葫芦岛煤码头工程所在海域进行潮流模拟,并在潮流模拟验证正确的基础上,通过对工程建设区域条件的分析,建立悬浮物输运模型,预测工程建设可能引起的悬沙含量和分布特征的变化,从而分析该工程的建设对海洋水质产生的影响,并以期对预测海床淤积和工程规划设计等方面具有一定实用价值。
Suspended sediment is one of important parameters of water quality, whose concentration can impact optical property such as transparency, turbidity, and aquatic ecological condition, and the dynamic change can impact the situation of seabed and construction of harbor. In this paper, suspended sediment model is established based on established three dimensional model of tidal current of offshore area of coal wharf of Huludao in Liaoning, and predict change of concentration and distribution of suspended sediment, so as to analyze the impact of this project to water quality and provide basis for change of seabed and harbor planning.
