Tailwater velocity
Web10 Oct 2014 · The outlet flow velocity in the end section of the culvert barrel depends in most cases on the culvert geometry, including the barrel slope, as well as on upstream … Webh) Outlet velocity. For higher values of the culvert slope, the outlet velocity increases. Assuming that the headwater height is twice the height of the barrel and with a culvert slope of 3%, the outlet velocity can exceed 6 meter per second under unsubmerged outlet conditions when there is no tailwater impact on barrel flow.
