摘要
研究了滩槽水流流速横向分布．对滩槽掺混区的横向涡粘性系数进行了计算，并给出其表达式．由此求解水深平均的水流运动方程，得到垂线平均流速横向分布公式．经验证，此公式与实测资料基本符合．
The transverse eddy viscosity coefficient of a mixing zone between the main channel and floodplain is calculated and an expression of the transverse eddy viscosity is given. Prom this, the formula of the transverse distribution of velocity can be obtained by solving the kinematic equation averaged along the water depth. It is proved that this formula is in agreement with the measured data on the whole.
