Déterminations hydrométriques — Mesure de débit dans les canaux découverts au moyen de structures — Déversoirs trapézoïdaux à seuil épais

This International Standard specifies a method of steady-flow measurement in open channels using a trapezoidal

broad-crested weir under modular and non-modular conditions. Consideration is given to the use of the weir in both

rectangular and trapezoidal channels.

Limitations to the use of the weir are given in 7.6 and 8.6.
