摘要
基于有关太湖湖流、波浪和水化学指标的实测资料,对太湖中由于风强迫作用和底层湖流分别产生的湖底切应力进行了计算,发现二者之间量级相差很大,得出了在风扰动情况下,由于波动而产生的湖底切应力对沉积物的再悬浮起着主导作用的结论,并估算了其临界值。
Based on the observed data about current,wave and chemistry in Lake Taihu,calculations of wave stress and current stress were conducted with a conclusion that sediment resuspension mainly results from disturbance caused by wind forcing.The critical wave stress for sediment resuspension is also evaluated in this paper.
