-It is worth to study near bridge structures, as it will disturb the bed material or may induce scouring right next to the piers.

- Irrigation canals, as there where some studies related to hydraulic jump application on increasing hydraulic head to lift water to irrigation canals.

Hydraulic jumps can cause serious problems in lined channels (e.g. concrete, masonry lining), which were designed to carry the design (flood) flow under supercritical fllow conditions, in the case where roughness is increased by e.g. rocks or boulders falling (or being dropped by funny people) into the channel and causing flow to become subcritical. In such cases the sudden increase of flow depth can lead to flows overtopping the banks. Many such channels exist in the Alps where torrents are flowing through villages. In the design process of such channels the possibility of suddenly increased roughness should be considered.

I hope that the following two references regarding the structures do you need to study hydraulic jumps can be useful for solving real problems.

Hydraulic Jump is a technique adopted to dissipate excess energy of a water flow in order to prevent erosion at a downstream of a structure on an artificial canal or a natural stream. If you introduce a drop (fall) structure on a stream channel you may need to tackle with excess energy and hydraulic jump is a good option to dissipate excess energy.

Regulators are hydraulic structure that hydraulic jump occurs at small gate opening.

I want to thank you for your answers and your documents that have enlightened me a lot of things.
