The present study is devoted to the analysis of scour downstream of a converging stepped spillway
equipped with a ski jump bucket. The energy dissipated by jets leaving the spillway can be divided
in two parts: one is the kinetic energy dissipated along the jet trajectory and another one is the
energy dissipated on the impact with the tailwater. Due to the jet impact, the riverbed is subjected
to turbulent pressure fluctuations resulting in the formation of a scour hole. Different experimental
conditions allowed to analyse the influence of different variables on the configuration of the loose
bed scour, namely: the tailwater depth, the flow rate and the exit angle of the ski jump bucket. The
results were compared to those presented by other authors. For some specific flow conditions, the
3D configuration of the scour hole was also determined.
