摘要
基于嵌套的平面二维潮流泥沙数学模型,模拟了海州湾海域滨海示范区围垦工程实施前后的潮流场、悬沙分布,并采用实测资料对模型进行验证,分析围垦工程后计算海域潮流场、悬沙场及海床冲淤场的水沙环境的变化情况。结果表明:围垦后研究海域整体的潮流场和悬沙场变化较小,但围垦后附近海域纳潮量有所减小引起围区附近流速减小,围垦工程附近基本呈现淤积的状态,工程左侧吹填坑淤积强度较大,临洪河口则出现局部冲刷。
Based on two dimensional nested gird tidal current and sediment numerical model,we simulate the tidal current field and distribution of suspended sediment in reclamation of Haizhou bay. The simulation fits well with the measured data. Analyzing the impact of the current field on the surrounding sea and the annual change in erosion and deposition after the project,we know that the whole calculated area tidal current and suspended filed change little. But decrease of the current velocity near the project causes reduction of the tidal prism. The deposition is presented near the project sea. The siltation intensity of the filling pit at the left is larger,and erosion is presented in part of Linghong river estuary.
