Abstract: In practical life the scouring of downstream bed of hydraulic structure leads to piping, undermining which is very serious case for a Hydraulic structural designer. To defeat these effect many researchers studied to depreciate the downstream energy. In the context of the previous study, In this project, the features of Hydraulic jump on spaced rectangular strip surface is studied and found out experimentally and this result is compared with a previous study as well as ANSYS. An experiment was performed for spacing such as S=3cm, where S is the Spacing between two sequential strips. Flow fluctuations are studied experimentally on a spaced base in a flat rectangular flume. 'Ten' experimental run was performed for spaced rectangular strip sheet considering differentdifferent Froude number ranging from 2 to 8 The important parameters of a Hydraulic jump, including the jump height, jump length was concluded as functions of Froude number and the height and extent of folds. These parameters are related to the consequences of the still bed which shows that rough channel decreases jump length and it is efficient for energy dissipation. The result showed that sequent depth and rise length reduced as compared to a smooth bed. With the help of 'ANSYS,' sequent depth and energy loss are calculated. Mass flow contour, Velocity Contour, Velocity Streamline, Pressure Contour, Velocity vector, Wall shear vector, Volume fraction are plotted. Which shows that providing spaced rectangular strip at downstream is good for energy dissipation .
