  2. 2 . based on the achievement of predecessors physical modeling and fundamental theory of hydrodynamic behavior of compound channel with rigid vegetated floodplains are studied in this paper . hydrodynamic behavior of compound with rigid vegetated floodplains is conclued
    在前人研究的基础上对河滩上种有树木的复式断面渠道的水流特性进行了试验研究,着重分析了滩地种树密度、排列方式对水流的影响。
  3. In this paper , some characteristics of flow movement and sediment transport are analyzed by using the flume experiment data . the cross section of compound channel can be divided into four regions : the undisturbed region in main channel , the interactive region between channel and plain , the undisturbed region in flood plain and the boundary region . in the undisturbed regions , the distribution of longitudinal velocity along the depth has the feature of lograithmic . whereas , in the interactive region , the longitudinal velocity does not obey the logarithmic distribution law , but it can expressed as a revised logarithmic function by using a wake function . on the basis of the kinematic equation the velocity distribution of transverse velocity is obtained . in the boundary region , the longitudinal velocity obeys the law of parabolic distribution . furthermore , according to the simplified diffusion equation , the transverse distribution of sediment concentration in the interactive region is deduced . the analysis is in good agreement with the measured data
    本文根据漫滩水流的运动特点,将漫滩水流的复式断面分为主槽平衡区、滩槽交互区、滩地平衡区及边壁区等4个区,并给出了各区宽度的经验公式.根据滩槽交互区垂线流速分布的变化特点,提出了附加尾流函数的对数流速分布公式.在简化水流运动方程和泥沙扩散方程的基础上,对滩槽交互区内垂线平均流速及含沙量沿横向分布进行了理论分析,提出了反映滩槽水流动量交换强度的横向涡量粘性系数及横向扩散系数的表达式,得到了漫滩水流垂线平均流速及含沙量沿横向分布的解析解,并与实测资料吻合较好
  4. 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
    采用adv对滩地种树前后滩槽交界区域的流速场进行了量测。分析了滩槽交界区域的垂线流速、紊动强度和雷诺应力的变化。将滩槽交界的动量传递描述为一表观应力,这个表观应力可以看作是交界面处的脉动函数并将其定量化。
