ISO 14139 is an international standard that discusses flow measurements in open channels using structures. ISO 14139 specifies the methods of measurement of flow in rivers and artificial channels, using any combination of standard weirs and or flumes in a compound structure. All structures can be operated in the modular flow range, but only a limited number of structures can be used
