ISO 4364:1997/Cor 1:2000 is an International Standard (ISO) that specifies a method for measuring liquid flow in open channels, focusing on bed material sampling. It is a technical corrigendum (Cor 1) to the original standard published in 1997, with a publication year of 2000, meaning it contains corrections or clarifications to the original standard. The standard is relevant to hydrometry and the measurement of liquid flow in open channels like rivers and canals.
