Description of Hydraulic Jump as a Waste of Energy

In order to prevent damages caused by the extraordinary energy of water at supercritical speeds and to eliminate the additional kinetic energy in such water, it is generally necessary to use special structures called (Energy dissipators) that are made downstream.In addition to removing water energy, these structures are also a mean of controlling and restraining hydraulic jump and creating conditions for its occurrence in a specific location.In this research, which has been compiled by descriptive research method, after introducing and recognizing hydraulic jump and resting basin, researches on the geometric arrangement of resting ponds were investigated and finally three different expansion ratios and five different heights of overflow edges were investigated.
