Parameters of Hydraulic Jump on Corrugated Beds

Analysis of Turbulent Hydraulic Jump over a Transitional Rough Bed of a Rectangular Channel: Universal Relations

“…The hydraulic jump on a corrugated bed has been studied by Ead andRajaratnam (2002), Tokay (2005), Yadav and Ahmad (2007), and Abbaspour et al (2009), in which the height of corrugation from crest to trough and wave length of corrugation play significant roles in the corrugated beds. Mohamed-Ali (1991), Negm (2002), Izadjoo and Bajestan (2005), and Bejestan and Neisi (2009) have considered the effects of roughened-bed stilling basin on the length of a hydraulic jump in a rectangular channel.…”

Steady two-dimensional free-surface flow over semi-infinite and finite-length corrugations in an open channel

“…The manner in which the boundary conditions are imposed in our numerical schemes for both the fKdV equation (8) and the fully nonlinear system (5)-(7) differs between the subcritical flow case and the supercritical flow case. In either case we must truncate the domain.…”

“…Working on this basis we assume that 1 and seek a solution to (8) in the form η(x) = N (x), where N = O (1). Substituting into (8) and taking the limit as tends to zero, we obtain the linearized form…”

“…Corrugated topography naturally arises in the flow of water over erodible beds in tidal estuaries, beaches, streams, and rivers [1][2][3][4][5][6]. Such flows have been studied experimentally using engineered corrugated topographies in rectangular open channels [7][8][9][10][11]. An important finding was that including a corrugation over part of the channel can provoke a hydraulic rise, which assists in slowing down the stream velocity and also enhances energy dissipation.…”

“…An important finding was that including a corrugation over part of the channel can provoke a hydraulic rise, which assists in slowing down the stream velocity and also enhances energy dissipation. Both of these outcomes may be advantageous in applications where it is desired to protect hydraulic infrastructures such as weirs, spillways, and gates [7][8][9][10][11]. Flow past corrugated topography is therefore an important problem for study.…”
