Cutthroat flume

[2] Under free-flow conditions the depth of water at specified location upstream of the flume throat can be converted to a rate of flow.

The result of these efforts was a flume that is simple in form and construction and that is well suited for use in flat gradient (low slope) applications.

Cutthroat flumes lack a parallel-wall throat section (hence the name) and has a flat-bottom to allow for installation in flat gradient channels.

The point at with the approach and discharge section walls meet is termed the “throat” of the Cutthroat flume.

For a given length, Cutthroat flumes of intermediate throat widths can be developed without the need for laboratory testing.
