OS GSO ISO 4371:2015 Scope
This International Standard 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 2 000 are admissible. This International Standard covers channels with the following types of cross-section, the nappe being unconfined:
a) trapezoidal;
b) triangular;
c) parabolic;
d) circular.
Using the measured depth at the end, the flow can be estimated.
