Course Description:
The full set of knowledge required to design a dam at a preliminary design level. It encompasses the selection of the appropriate dam type, the siting and sizing of the basic technical elements during dam construction and the full set of hydraulic calculations for all hydraulic safety support structures (diversion tunnel, spillway, etc.).
Prerequisite Knowledge
Geology, Soil Mechanics, Hydrology, Fluid Mechanics, Open channel and pipe hydraulics.
