Water Resources Engineering: You have designed a channel to to transport 5 m3/s using the most efficient rectangular section. The Manning's roughness coefficient is 0.019 and the bed slope is 0.0001 m/m. For this channel, determine: a. The normal depth b. Is the flow subcritical or supercritical c. Calculate what the new width of the channel would need to be to force the flow of water to be critical and state what the depth of water would be in this new channel. Neglect head loss through this transition (Note: this will no longer be the most efficient section). d. Show the transition on a specific energy curve.

Open Channel Flow

Open channel flow is a branch of fluid mechanics. It deals with the flow of fluid in an open conduit or free surface. In an open channel flow, gravity induces the flow of water whose surface is open to the air. This flow is free-falling rather than confined in rigid body conduits. The open channel flow depends upon two parameters that are the cross-section of the conduit and the velocity profile. Practical examples of open channel flow are streams, rivers, canals, and other drainage systems.In open channel flow, the cross-sectional area of at least one of the sides is exposed to air, and the surface of water faces atmospheric pressure. This flow is also known as free gravity flow. The cross-sectional area of the conduit can be either man-made or a natural channel. For instance, the flow in rivers and streams are natural conduits, and the flow in a canal and sanitary systems are man-made or engineered channels.
