Abstract: The effect of a continuous, transverse sill on the hydraulic jump in a rectangular channel is analysed. Based on the results pertaining to the classical jump, the sill-controlled jump may be shown to correspond to a perturbed classical jump, particularly as regards the overall jump pattern. A novel normalisation procedure is introduced by referring to the roller length of classical jump. Further, the two- and three-dimensional flow patterns are discussed. The design procedure involves both the hydraulics and the erosion sensitivity of tailwater bed.
