Abstract
The aim of this experimental study is to analyze the ratio of the relative t
hreshold of the
hydraulic jump evolving in a rectangular channel composed with a rough minor bed.
functional relations, in dimensionless terms, as a function of the Fr oude number and of the
roughness were obtained.
Indeed, for a fixed initial height h
1 , th e increase in the incident Froude number causes both the
displacement of the step downstream. therefore, it corresponds to a length Lj of the step and
Lr of the roll, as well as a height h 2 downstream of the step and a height S of the threshold.
