FLOWOPENCHANNEL

Open channel flow occurs when liquid flows in a conduit or channel with a free surface -- like rivers, streams, canals, and irrigation ditches -- as opposed to the closed pipes common in industrial and process control environments. Other examples of open channel flow include flow in water treatment plants, storm and sanitary sewer systems, industrial waste applications, sewage treatment plants, and irrigation systems... Flow in uncovered channels like irrigation ditches depends on gravity. Likewise, flow in partially filled closed conduits, such as culverts and drain pipes, also is gravity-dependent... What is slightly confusing about the term open channel is that that the flow of liquids in partially filled pipes -- when not under pressure -- is also considered open channel flow. Water flowing through a culvert running underneath a street is considered open channel flow, for example even though the channel is not actually "open." Likewise, flow in sewers and tunnels are classified..
