  OPEN CHANNELS A n open channel can be defined as the structure through which the upper portion of liquid flows freely exposed to the atmosphere and under the atmospheric pressure. The flow of water through the open channel which has certain bed slope is purely due to the action of gravity and pressure difference plays no role in the flow of water like of closed channels or as like in pipe flow. Open channels can be natural like rivers, streams or it can be artificial. While artificial refers to the man made features like canals, culverts etc. Mostly rectangular or trapezoidal shape is preferred while designing the open channels. But due to the high discharge rate of circular shaped channel for given area is highest, it is also constructed sometimes .While constructing irrigation canals, open type is preferred with rectangular or trapezoidal in shape and while constructing sewer, an oval or egg shape is preferred. While constructing sewer, an open type is preferred due ...
