Abstract
This thesis concerns the determination of the hydraulic jump properties over rough surface beds. Both theoretical and experimental studies of the hydraulic jump occurring on smooth and rough test beds are carries out.
Prepare the various test beds 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.
