A symmetric compound channel in overbank flow has a main channel with a bottom width of 30 m, side slopes of 1:1, and a flow depth of 3 m. The floodplains on either side of the main channel are 300 m wide and flowing at a depth of 0.5 m. The mean velocity in the main channel is 1.5 m/s, while the floodplain flow has a mean velocity of 0.3 m/s. Assuming tha the velocity variation within the main channel and the floodplain subsections is much smaller than the change in mean velocities between subsections, find the value of the kinetic energy correction coefficient alpha.

There is a rectangular channel that will be excavated downstream of a dam after a stilling basin both with a width of 15 meters. The depth of the wather flow upstream of the dam is 4.27 meters and the discharge flow above the dam is 112.5 cubic meters per second. the channel wil be excavated in earth and n = .o25 and maintains a uniform flow depth under a subcritical flow regime. I need to determine 1. the bottom channel slope needed in the downstream channel and 2. the length of the stilling basin if the dissipation stucture starts at dissipated along the structure. The design should consider that the flow depth at the end of the still basin is similar to the flow depth in the channel. For a more realistic approach in the design, the head loss between the station upstream of the dam and the station at the beginning of the still basin is 10% of the velocity head observed at the beginning of the basin

) A rectangular channel 1.2m wide carries 1.13 cumecs at a depth of 850mm under the uniform flow conditions. If a streamlined bridge pier 300mm wide is placed in the middle find the local change in depth. What is the maximum thickness of the pier if there is to be no change in upstream conditions?
A trapezoidal channel with sidewalls of 60 degrees has a bottom width of 4 m at total depth of 5 m and has a constant bedslope of 0.005. A flow of 40 m3/s fills the channel to a depth of 3.5 m, the maximum for normal operation. Downstream a topographic constriction requires that the channel be rectangular with a maximum width of 4 m. Assuming no changes in materials and no energy losses, estimate the depth in the downstream rectangular section and recommend a total depth for the rectangular channel.
