Abstract

Specifies the method of measuring water flow in rivers and artificial channels under steady flow conditions using round-nose horizontal broad-crested weirs. It is technically identical with and reproduced from ISO 4374:1990.

Scope

This International Standard deals with the measurement of flow in rivers and artificial channels under steady flow conditions using round-nose horizontal broad-crested weirs (see figures 1 and 2).
The flow conditions considered are limited to steady flows which are uniquely dependent on the upstream head. Drowned flows, which depend on downstream as well as upstream levels, are not covered by this International Standard.
The round-nose horizontal broad-crested weir has a good discharge range and modular limit and is appropriate for use in small- and medium-sized installations. It is particularly robust and insensitive to minor damage.
