摘  要:
基于MIKE 21FM模型建立了茅尾海海域二维水动力模型,通过验证,结果与实测资料吻合良好。利用建立的水动力模型分别模拟出生态修复工程完成前后该海域的流场,并对比其变化情况。基于已建立的水动力模型,耦合泥沙输运模块建立茅尾海冲淤模型,分别模拟了生态修复工程前后茅尾海海域在波流共同作用下的泥沙输运情况。对比结果表明,工程的实施能够极大地避免岸滩冲刷,有效保护红树林。

摘  要:
A 2-D hydrodynamic model of Maowei Sea was established based on MIKE 21,which was verified by the real measurements.With the established model,the tidal current field after ecological restoration engineering completion was simulated and the change of the tidal current field before and after engineering completion was determined.The erosion-siltation model was established by combining the hydrodynamic model and sand transport module,which aided to,calculating the sediment transport of Maowei Sea caused by wave and current.Comparing the simulated results before and after engineering completion,we found that the implementation of the engineering protected the seashores greatly from scouring,and mangroves from destroying.
