Key Developments in the History of ; Arch Dams ... It is rather astonishing that the Romans only sparcely applied the arch in dam constructions, a design otherwise so masterfully employed in their buildings and bridges. One of the few true arch dams built by the Romans was located in the Vallon de Baume, France in order...

With arch dams it is convenient to construct gated openings in the shell structure at some distance below the crest of the dam, ensuring that the discharging jets fall well clear downstream. A line of six such gates is used in the design of Kariba Dam.
