Dam Engineering and Safety

The details of an experimental hydraulic study on a scale model of a particular type of spillway for the Savage Mills dam project on the Yamaska River near Granby in the Province of Quebec are presented. This multipurpose dam is a joint project between the Office of Planification and Development of Quebec and the Natural Resources Department of the Province of Quebec. Preliminary studies have shown that the use of a standard type of spillway such as a shaft spillway or a side channel spillway would be less economical than a structure that would make use of the diversion channel which is usually only a temporary work. A particular type of spillway, being a combination of the side channel and shaft spillways which discharges into the diversion channel, has then been proposed by engineers of the Department of Natural Resources. In order to evaluate the capacity, the operation and the efficiency of that structure, a scale model study has been carried out. That study has established the hydraulic properties of the proposed structure and has enabled one to properly design its different components.
