Abstract:

An experimental investigation of the effectiveness of walls, or sills, across a culvert outlet between flared wingwalls established that moderately high velocity flow in a culvert on a steep grade could be forced to expand in a hydraulic jump to fill the barrel by the use of sills, particularly if the culvert were operating at low discharge rates, that is, up to 2.5 d to the power 2.5. The outflow on an apron of width 3.5 d occurred with specific energy about one-fourth of that of the culvert flow.
