| 摘 要： | 通过水槽试验,研究了植被层以下和植被层以上垂向流速的分布规律。建立了植被层以下垂线流速的三次函数公式和植被层以上垂线流速的对数公式,同时提出了相关系数的确定方法,并通过试验数据和其它水槽流速资料进行验证,表明提出的明渠流速分布律与实际分布是比较一致的。

| Abstract: | Distribution law of vertical velocity of water flow inside and above the vegetation by water channel experiment is reviewed in the present paper.The relationship of cubic and logarithmic function to describe the velocity distribution of water flow inside and above vegetation is developed,and the ascertain method of correlative is proposed.Then according to experiment data and velocity of other water channels,the velocity distribution law given in this paper is in accordance with the real velocity distribution in open channel. |
