Question

Assuming that the peak flow of the Quebrada de Oro in Miradero, Mayagüez basin is 3,000 cfs for a duration of 24 hours and 100-year recurrence, find: 1- The dimensions of the trapezoidal channel in concrete that allows this flow to be carried peak. For this, it is indicated that the maximum strip of land available for build channel is 50 ft. Assume for the solution a slope of 0.5%. 2- Calculate the critical depth in the channel (yc) and define what type of flow occurs in the channel (subcritical, supercritical, critical). The flow condition obtained is the adequate on the channel? Explain in detail.
