One of the most frequently encountered cases of rapid varied flow is the hydraulic jump. It occurs
when a supercritical flow has to change into subcritical flow. Nowadays jump study upon sloping beds,
especially adverse slopes, is important because of the length of jump and the energy loss. In this research jump
study has been done upon four adverse slopes -0.00125, -0.0025, -0.00375 and -0.005 in two cases of rough
and smooth bed. The results showed that the Sequent depth ratio and the length of jump upon smooth bed has
been more than rough bed for the same slopes and Froude numbers. Also comparison with percentage of the
energy loss, more energy loss has occurred upon rough bed than smooth bed.
Key words: Energy loss, hydraulic jump, length of jump, sequent depth, , ,
