标准范围

规定了一种估算光滑、笔直、矩形棱柱形明渠中清水亚临界流量的方法，明渠具有垂直落差，可自由排水。利用端部测得的深度，可以估算有约束推覆体和无约束推覆体的矩形渠道（水平或倾斜）中的流量。

Specifies a method for the estimation of sub-critical flow of clear water in smooth, straight, rectangular prismatic open channels with a vertical drop and discharging freely. Using the measured depth at the end, the flow in rectangular channels (horizontal or sloping) with confined nappe and unconfined nappe may be estimated.
