An abrupt rise of 1m was designed to control a hydraulic jump generated after a 5 m wide sluice gate with an opening of 0.25 m by a flow discharge of 15 m³/s. The flow depth over the rise was 1.25 m. (a) Discuss about the stability of the jump (Submerges or washes out?). (b) Find the flow depth over rise to form a stable jump at x=5(h+y3) if the abrupt rise reduces to 0.75 m.

Principles of Seepage

In hydrology, when water flows down in a pore or crack of unsaturated soil due to gravity, the deep layer of soil is called seepage. It is the slow movement of water in the soil layer. Seepage is mainly found near hydraulic structures and is responsible for the stability of earthen-type hydraulic structures.
