Cavitation in Chutes and Spillways

Stated purpose: "to give the designer of hydraulic structures both an understanding of cavitation and the design tools necessary to eliminate or reduce the damaging effects of cavitation in hydraulic chute and spillway structures." Chapters 1-7 discuss highlights of cavitation theory, cavitation characteristics of typical surface irregularities (applicable to open and closed conduit systems), cavitation damage, the influence of geometry, aeration and aerators, recommendations for design (surface tolerances, etc.), and USBR field experiences. Appendices contain algorithms to calculate cavitation and damage indexes for open channel flow situations, a program for plotting cavitation and flow characteristics, descriptions of two programs to investigate the effect of changes in the invert geometry on the cavitation index, a description of a computer code used to design aerators, and the description of a program to determine the damage potential of a structure using historical data.
