摘要

利用安装在剖面仪上的后向散射光纤激光多普勒测速仪(LDV)测量了海岸带底边界层的速度。LDV的速度实现率被用来获得泥沙浓度和通量的剖面。介绍了提取浓度和通量剖面信息的仪器和方法。有关流体力学结果的分析将留待以后的文章进行。

Velocity, concentration and flux of sediments in a coastal bottom boundary layer with a laser Doppler velocimeter

A backscatter fiber-optic laser Doppler velocimeter (LDV) mounted on a profiler was used to obtain velocity measurement in a coastal bottom boundary layer. The rate of velocity realization from the LDV has been used to obtain profiles of sediment concentration and flux. The instrumentation and the method for extraction of concentration and flux profile information are described. Analysis of results of interest to hydrodynamics is deferred to a later paper.<>
