Abstract:Slit-type bucket energy dissipator was widely used in high dam construction because of its significant energy dissipation effect .A generalized physical model experiment is conducted to investigate the variation of several hydraulic characteristics in the slit-type bucket energy dissipator such as the water line , hydrodynamic pressure and water tongue trajectory.Nice sets and thirty six working conditions are tested with different combinations of the Froude number , shrinkage ratio , and pick angle .The experiment results provide useful theoretical supports for further study and optimi -zation design of this energy dissipator .
Keywords:slit-type energy dissipator  experimental study  hydraulic parameter  Froude number
