Irregularities in flow surfaces of hydraulic structures operating at high velocities have been the source of serious damage by cavitation. The type of surfaces often encountered in construction are shown and many examples of cavitation damage induced by the irregulatiries are shown photographically. Charts from which critical sizes of some of the types can be determined are presented. Methods used to reduce the irregularities to acceptable tolerance are noted and the use of aeration slots and tunnel offsets used in recent designs to eliminate cavation damage that would otherwise occur at the irregularities is reviewed.
