خTo reduce the construction costs of stilling basins of hydraulic jump type is sometimes, novel geometries are sometimes used to adopt the basin to the upstream and downstream sections without any transition structures. Otherwise, any changes in the geometry of the basin would cause changes in the conditions and characteristics of the hydraulic jump. In this study, the effects of variation in b...

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...
The hydraulic jump has been studied as an important method for energy dissipation downstream water structures. Several methods have been used to optimize the hydraulic jump length. One of the common methods was the use of end sill. Steps may be used to control the location of the hydraulic jump downstream of hydraulic structures. Extensive studies have been conducted to investigate the effect o...

One of the most important problems in the design of a stilling basin is determination of the exact location of the hydraulic jump or stabilization of the hydraulic jump. In the present study, the effects of different forms of end sills on hydraulic jump characteristics were studied. The experiments were carried out for three different forms of end sills, rectangular, square and stepped, with th...
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...
