Abstract: In order to give a reasonable design to prevent a spillway from a given maximum cavitation damage, a fuzzy model which is used to distinguish five cavitation erosion intensities is set up in this paper. Cavitation index of flow, velocity of flow, the content of air in flow, surface material of a spillway and operating time in a flood period are comprehensively considered in the model which could be used to design a spillway surface optimally according to its allowable cavitation dam age extent or to check a possible cavitation damage on an existing engineering.
