Specifies the method of measuring water flow in open channels under steady flow conditions using triangular profile weirs. It is technically identical with and reproduced from ISO 4360:1984.

This International Standard specifies methods for the measurement of the flow of water in open channels under steady flow conditions using triangular profile weirs. The flow conditions considered are steady flows which are uniquely dependent on the upstream head and drowned flows which depend on downstream as well as upstream levels.
