Can waterways which are prone to flooding be dug deeper to help prevent flooding? Like just digging big trenches through the bed of the waterway?
In: 6
Digging trenches in the bed of a waterway won’t accomplish anything. Imagine you have a stream. Dig a hole in the bottom of the stream bed. The hole immediately fills with water from upstream as the stream continues to flow. The level of the stream doesn’t drop. Now a flood comes along. The hole you dug is already full of water, so no more will go in there. The stream rises just like it would have if the hole had never been there.
