Literally how do dams work? Also why? Didn’t we exist without them or why do we need them? Also when the damn is not open, how come the river side doesn’t like dry up because it’s not flowing? Idk if that makes sense.
In: Engineering
For a dam to make sense, there needs to be a source of water like a river or creek. Without water, it would just be a wall.
Build a wall inside that river and across it. That pools up the water behind that wall until it rises and spills over. This wall is the dam.
The water on the other side CAN dry up but most of the time, the dams are built with pipes (gates) which allow the dam operator to release a steady stream of water. As long as the river supplying the water and the release from the gates are equal, the water level behind the dam remains constant and there will still be water down stream.
