Storm water flows in Channels and Conduits
Storm water flows in channels/ conduits in contact with atmospheric air is said to be an open channel flow or free-surface flow.
If the rate of discharge remains constant with time at a given cross-section, the flow is said to be steady, and if it varies with time, then the flow is called unsteady flow.
If the velocity and depth of flow are the same at every section of channel/conduit, the steady open channel flow is said to be uniform flow, and if the velocity, depth or both are changing then the flow is known as non-uniform flow.
When fluid flows in a parallel direction without interruption between each layer, it is defined as laminar flow, and if it moves in irregular paths, it is said to be turbulent flow.
Storm water flows in open channel/conduit are under unsteady and turbulent flow conditions but to simplify the design process, it is assumed to flow in steady turbulent conditions either uniform, non-uniform gradually or rapidly varied flow.
Flow Formulae are applicable in design computations of storm channels/ conduits
