Abstract
Until now, hydraulic research of stepped spillways has focused on characterizing aspects as: the different types of flow that occur on the chute, the air inception processes, the potential negative effects associated to the risk of cavitation, the energy dissipation produced by the steps, or the discharge capacity of the spillway. These investigations, however, have focused on stepped spillways with sidewalls, which impose a constant width along the dam. This paper shows the first results of the...
