Peterka 2015-03-04 Although hundreds of stilling basins and energydissipating devices have been designed in conjunction with spillways, outlet works, and canal structures, it is often necessary to make model studies of individual structures to be certain
WebIn the design of hump type stilling basin, the size and shape of the hump is the most important part. The hump should not be too high otherwise the jet would not spread out completely to the full width of channel. If jet is too low, tailwater for small flows will submerge the hydraulic jump. The level of crest of the hump should be the same WebBureau of Reclamation
