Bolt-On Cutthroat Flume Wing Wall

A close-up view of a flat wing wall bolted onto the discharge of a galvanized steel Cutthroat Flume.   The wing wall here is loosely bolted on to check fit. The wall is removed prior to shipping to both reduce shipping costs as well as to make it easier to transport the flume out into the field.

Wing walls are simply walls - at the inlet and/or outlet of a flume - that direct flow into/out of the flume so that flow bypass doesn't occur.  Inlet wing walls should be curved or angled so that the flow comes smoothly into the flume - without turbulence or flow separation.  Outlet wing walls can be flat or angled - curving is unnecessary.  The goal of the outlet wing wall is simply to transition the flow back into the downstream channel - and in such a way that scour doesn't occur.
