- hinkley 3y agoWe are doing something fundamentally wrong with sediment management in dams. Practical Engineering talks about how dams cause erosion downstream because the suspension capacity of the water is not occupied with material from upstream, and nature abhors a vacuum. We need some way to continuously siphon sediment and expel it with the exhaust from the hydro and overflow pipes.
