Effect of Sill Arrangement on Maximum Scour Depth Downstream of Abruptly Enlarged Stilling Basins
Scour downstream (DS) of hydraulic structures (HS) may endanger the safety of the structures if the necessary precuations are not considered during the design stage. Normally, different measures produce different effects on reducing the maximum scour depth DS of HS. One of the important HSs is the abruptly enlarged (or sudden expanding) stilling basins. In this paper, the effects of different a...
متن کاملInvestigation of B-jump Negative Step in Radial Stilling Basins
Presence of steps in radial stilling basins affect positively or negatively the characteristics of the free hydraulic jumps depending upon the type of the step, the height of the step, the position of the step in the basin and the dominant flow conditions. The effects of all these factors on the characteristics of the free radial hydraulic B-jump are addressed through the present experimental i...
متن کاملTheoretical Criterion for Stability of Free Hydraulic Jump on Adverse Stilling Basins
Hydraulic jump on adverse stilling basin is an unstable phenomenon which causes some complexities in controlling of the jump. This paper considers the stability of free hydraulic jump on adverse stilling basins from a theoretical point of view. A minimum value of upstream Froude number is needed to produce the free hydraulic jump on adverse stilling basins which was presented by a theoretical...

متن کاملOptimal Waterway Passage in Submerged Curved Deflector for Minimization of Local Scour
Many of the huge structures like New Esna, and New Nega Hammadi Barrages face a great harmful caused by local scour downstream (DS) their stilling basins. It is planned to redesign many of these structures to minimize these harmful impacts of the DS local scour. This research paper presents the results of an extensive experimental investigation on using an optimized submerged curved deflector t...
