Cor, that's a massive dam - I hadn't really appreciated that you might want to build something that big for the sake of flood management, rather than because you want to store the water for later (e.g drinking water reservoirs).

Does a structure like that aim to produce constant river flow, averaging out the wet and dry seasons? Is this sort of thing only common in places with variable climates?
