标准范围

规定了一种估算光滑、基本水平、垂直下降且自由排放的直明渠中清水亚临界流量的方法。2000年允许出现不大于1的平缓正坡度。覆盖具有以下类型横截面的渠道，推覆体受到限制:a）梯形；b） 三角形；c） 抛物线；d） 通告。

Specifies a method for the estimation of subcritical flow of clear water in smooth, essentially horizontal, straight open channels with a vertical drop and discharging freely. Gentle positive slopes not greater than 1 in 2000 are admissible. Covers channels with the following types of cross-section, the nappe being confined: a) trapezoidal; b) triangular; c) parabolic; d) circular.
