波－流共同作用下泥沙混合特性的实验研究

Abstract First of all, the qualitative relation among suspended sediment.concentration and currents as well as waves is established by theory analysis.and continuous filed observation; then the sediment experiments for the.different conditions are carried out in the wave-current-sediment flume which.is new built by the State Key Laboratory of Estuarine and Coastal Research,and finally, the important effect of waves on sediment transport is further revealed by analyzing the experimental data.

利用具有特色的波－流－变坡－泥沙水槽，设计并进行不同波、流、坡度等条件下的泥沙实验，确定不同波－流条件下的泥沙混合系数，建立泥沙混合系数与破波类型及波浪特征量间的关系，深化人们对于波－流共同作用下泥沙混合特性的认识。该项研究既能促进河口海岸区域泥沙运动研究的发展，又可为人们求解波－流共同作用下的泥沙场提供合理参数。
