STUDY OF THE EXPERIMENTAL APPROACH OF THE RELATIVE THRESHOLD OF THE HYDRAULIC JUMP EVOLVING IN A RECTANGULAR CHANNEL OF COMPOSED SECTION WITH ROUGH MINOR BED
(university of el oued/جامعة الوادي, 2021-05-01) Djamaa, W; Ghomri, A; Khechana, S
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.
