Baffle pier experiments in hydraulic jump type of stilling basins indicate that wedge-shaped blocks with a vertex angle of 120○ dissipate more energy in a shorter length than rectangular blocks. The wedge blocks with the downstream portion cut-back at an angle of 90○ are expected to be free from cavitation.
