Why is this work in the frame?
A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.
No Canadian affiliation. An affiliation-only frame — the usual design — would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract
This study was conducted to investigate the velocity distribution and attenuation in free jumps on rough beds. Based on the length scale of jump length L j , the velocity distribution of the free jump on a rough bed can be divided into four parts by three typical sections where are in the position of x=0.4L j , x=0.8L j , and x=1.2L j . It seems that the velocity distribution near section x=0.4L j is the most uneven. The velocity attenuation rate in the bottom half of the water is larger than that in the top half of the water. The attenuation of the maximum velocity u m is mainly done from x=0 to x=0.8L j . The results show the mixed triangular corrugated floor increases the resistance of hydraulic jump development and is very efficient in energy dissipation.
