Abstract
In this study, a physical hydraulic model
investigation was conducted to evaluate the performance
of a stepped overflow spillway. The spillway
has a standard ogee profile with continuous steps
cut into the spillway weir down—stream face just
below the crest to the toe. The experiment was
carried out on three models of the spillway weir,
two of the models were of the same scale ratio 1:1OO
of the prototype, one model has the stepped down —
stream face while the other is unstepped, which was
used to compare their test results. Discharges were
allowed to pass over each of the weirs and readings
were noted and compared. The third model is a bigger
model of 1:50 which is also of the stepped face type.
The investigation demonstrated that this stepped
spillway is quite effective at dissipating energy
and smooth flow transition from the spillway crest
to the stepped face is easily achieved
