Abstract
Recent advances in technology have permitted the construction of large reservoirs and chutes. These developments have necessitated the development of new design and construction techniques, particularly with the provision of adequate flood release facilities and safe energy dissipation. The latter may be achieved by the construction of steps on the chute. This paper discusses issues of the operation and safe design of stepped chutes. It describes the operation of several structures worldwide, focusing on accidents and failures. The causes of failures are analysed and discussed. Problems specific to stepped-chute design are discussed in the light of over 20 accidents, and common mistakes are described. The safe operation of several old stepped chutes and the experience gained from past failures must be used to gain further expertise and knowledge about the hydraulics of stepped chutes.
