Ski-jump bucket type energy dissipators have been under operation for some time past with success in a number of (dams in India and, abroad. When the river bed is rocky, and tail-water low, it is economical to use a ski-jump type of bucket which can operate under fluctuating conditions of tail-water.
Based on a dimensional and statistical analysis of the various ski-jump buckets adopted and proposed to be adopted in India, graphs have been drawn and equations worked out to serve as a guide for the fixation of the radius of the bucket and the exit angle before finally proceeding with its testing on models.
