Its main goal is to study how the roughness of the channel bottom influences the characteristics of the hydraulic jump, in particular its efficiency and its generalized profile. . To better illustrate this impact, the experimental results are presented in the form of graphs. These graphs highlight the variation in efficiency as a function of the Froude number of the incident flow for the two bed configurations (minor and major). Likewise, they show the variation of the Y ratio as a function of the X ratio, where Y and X are dimensionless variables.enhydraulic jumpcompound rectangular channelrough minor bedjump yieldgeneralized profile of the jump.Other
