Abstract

High velocity water jets discharged continuously from radial gates into the stilling basins at the Zoekfonteln pipeline control works create conditions conducive to cavitation. Sources of cavitation are primarily roughtness on the concrete walls and floors of the chutes leading Into the stilling basins, and shear zones between fast moving and slow moving water in the hydraulic jumps in the stilling basins. Cavitation from the first source was minimized by the use of special formwork to provide ultra-smooth concrete surfaces, but these measures could not be expected to be entirely successful, so aeration was also Introduced.
