EXPERIMENTAL STUDY OF THE SEQUENT DEPTHS RATIO OF THE HYDRAULIC JUMP IN A RECTANGULAR COMPOUND CHANNEL WITH A ROUGH MINOR BED
Abstract
The present knowledge on the behavior of hydraulic jumps is only for smooth, horizontal channel beds. Very limited studies have been reported in the literature on the performance of hydraulic jumps on rough beds.
The objective of our study is to investigate the sequent depth ratio of hydraulic jumps in a rectangular compound channel with a rough minor bed under different flow conditions using laboratory investigations. A series of experiments were carried out in a rectangular compound channel flume, which consists of artificially roughened beds formed by homogeneous plastic pellets.
The hydraulic parameters, such as first sequence depth h1, second sequence depth h2, and flow rate, were measured for different bed roughnesses. The analysis of experimental data showed that the rough bed reduces the sequent depth ratio more than those on smooth beds while creating a high energy loss. With the availability of a large number of experimental data on hydraulic jumps over rough channel beds, mathematical formulations were obtained to express the sequent depth ratio of hydraulic jumps to roughness parameters such as roughness height.
