This experimental study analyzes submerged hydraulic jumps generated in a 1.05-m wide stilling basin that receives overflow rectangular impinging jets, with the vertical distance between sharp-crested weir and bottom of plunge pool being 2.20 m. Five downstream non-developed nappe jets were analyzed, falling distances to break-up length ratios 0.76 0.78. The impingement velocity range was from ...

Structures like blunt-nosed chevrons, log deflectors and double-winged frames help in modifying the flow regime channel by concentrating increasing navigability. Moreover, they create scour pools downstream stilling basin, which can be used either as fish refuge or an in-stream storage site for previously dredged material. In this respect, use of wood debris form bundles has gained attention ab...
