If you ask me, there’s almost nothing on this blue earth more fascinating than water infrastructure. Watch on Nebula: https://nebula.tv/videos/practical-engineering-how-different-spillway-gates-work Almost all dams need a way to release excess water when the reservoir is full. Although many dams use uncontrolled spillways, gated spillways provide more control over the flow, allowing us to build smaller, more cost-effective structures. There are countless arrangements of mechanical devices that have been used across the world and throughout history to manage the flow of water. But, modern engineering has coalesced to variations on only a few different kinds of gates.
