What is Open Channel Flow?
Open channel flow refers to the flow of liquid (usually water) with an open surface exposed to the atmosphere. It is a type of flow that occurs in natural channels like rivers and streams, as well as in man-made channels like irrigation ditches, canals, and sewer systems. In open channel flow, the water is subject to atmospheric pressure. Some of the key characteristics of open channel flow are a free surface and gravity-driven flow.
