Subcritical Flow

“What are the special properties of slow-moving, tranquil flows in channels?”

Slow-moving, tranquil flows in channels may seem simple. But if you dig deeper, you will find it more interesting. These flows, known as Subcritical Flows, are typically deep and dominated by gravity. The slow-moving and gravity-centric flow can be greatly affected by downstream elements like dams because it does not have enough momentum to overcome such heavy changes.
