Specifies a method for the estimation of sub-critical flow of water in smooth, essentially horizontal, straight open channels with a vertical drop and discharging freely. It is technically identical with and reproduced from ISO 4371:1984.

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.
