WebJun 1, 2014 · A parabolic flume (Fig. 1) is a type of Venturi flume [8], can only be used under the condition of free flow.The flow conditions upstream of a discharge measurement structure are governed by the geometry of the structure and the approach channel, and by the physical properties of the water. WebSo measuring flow rate (CFS) can be done by simply measuring the depth of the water upstream. The biggest difference between a weir and a flume is that a weir creates a pond upstream of the weir, while a flume requires much less upstream depth. This often prevents weirs from being used in flat canals or ditches, or canals with little head upstream.
