| 摘 要： | 运用ECOMSED模拟风速为6.5 m/s定常东南风作用下太湖流场及波浪场,对模型的适用性及可靠性进行验证;在此基础上进行波流共同作用下沉积物再悬浮数值模拟,得出沉积物-水界面切应力及水体中悬浮物浓度分布。结果表明:太湖有效波高范围在9~29 cm之间,有效波高的空间分布与风速、风向和水深有很大的关系,同时波浪对切应力会产生很大影响,而切应力的分布决定了悬浮物浓度的分布,风浪及地形要素是导致太湖悬浮物浓度变化的重要因子。模拟结果与现有实验成果较吻合,说明运用该模型模拟太湖沉积物再悬浮的结果可靠。

| Abstract: | The Estuary Coastal Ocean Model incorporated with Sediment(ECOMSED) model was used to simulate the flow and wave field under a steady southeast wind of 6.5 m/s in Taihu Lake,and the suitability and reliability of the model was verified.Based on this,numerical simulation of sediment re-suspension was carried out with the joint action of waves and currents,and the distributions of shear stress and suspended matter concentration on the water-sediment interface were obtained.The results show that significant wa... |
