ABSTRACT .
This paper concerns the determination of the hydraulic jump properties over rough impervious beds. An extensive experimental study of the hydraulic jump occurring on smooth and rough test beds are carried out. Course sand and gravel of different sizes are used to prepare the various test beds for the experimental investigation. Different methods for describing the measure of bed roughness are included in this investigation. Free hydraulic jumps are formed in a rectangular flume downstream weir models of different geometrical scale ratios to obtain various inlet flow conditions. The experiments are carried out with different rates of discharge to cover wide range of Froude number. The experimental results of the properties of hydraulic jump for various flow conditions and different bed roughnesses are graphically presented in this paper. A useful empirical relation is deduced to give the ratio of the jump length over a rough bed to the corresponding length over asmooth bed as a function of the relative roughness height. |
