摘要: 应用光学和声学泥沙剖面监测系统,进行1991、1994和1995年3个航次的椒江河口最大混浊带纵横剖面和时间剖面观测.在受控于潮流和径流对比条件的周期性调整基础上,椒江河口浮泥层还表现出非主流聚集趋向和洼地聚集趋向,促使最大混浊带保持对边界条件十分敏感的泥沙储库.Abstract: By using optic and acoustic sensors,the fluid mud layer was detected in turbidity maximum of the Jiaojiang Estuary during thre:cruises carried out in 1991,1994 and 1995.Records of time series of stations and transects across and along the river channel were collected.The data reveal that,in addition to the cyclic migration corresponded to the river runoff and tide prism.the fluid mud layer tends to concentrate on depressions or on one side of channel opposite its current-dominated channel.Such two tendencies result in a large suspended sediment reservoir being very sensitive to the boundary conditions of the turbidity maximum.
