声学悬浮泥沙观测系统的研制和应用

Development and application of an acoustic suspended sediment monitoring system

为观测水中悬浮泥沙的浓度剖面、监测水中污染物及研究近岸海区泥沙的迁移和沉积，研制了声学悬浮泥沙观测系统（ＡＳＳＭ）．总结了设计时主要技术参数的确定及解决关键技术的方法。应用此系统观测长江口悬浮泥沙，得到典型悬浮泥沙浓度剖面。

An acoustic suspended sediment monitor (ASSM)has been developed for the observations of sus- pended sediment concentration profilers in water, monitoring pollutants in water and for the studies of coastal sediment transportation and deposition. The determination of main technical parameters and the methodology of resolving key technique. are reviewed. The ASSM was applied to observe the suspended sediment in the Changjiang River Estuary, typical suspended sediment concentration profilers are obtained.
