3. a three - dimensional - acoustic doppler velocimeter has been used to measure the velocity and turbulence in a compound channel with vegetated and unvegetated flood - plains. particulary in the interface region between main channel and floodplain. the distribution in three coordinate directions of velocity and turbulence intensities and the renolds stresses are presented. the momentum transfer at the main channel flood - plain interface can be described as an apparent shear stress which can be quantified as a function of the local turbulence at the interface
採用adv對灘地種樹前後灘槽交界區域的流速場進行了量測。分析了灘槽交界區域的垂線流速、紊動強度和雷諾應力的變化。將灘槽交界的動量傳遞描述為一表觀應力，這個表觀應力可以看作是交界面處的脈動函數並將其定量化。 -
