nd за Problem 4.5: An uncontrolled overflow spillway of 5 m height will be designed to evacuate Q. = 400 m³/s. The design tailwater depth is estimated to be 4 m. The approach channel and the downstream of the spillway are rectangular in cross- section having widths of 40 m. Headloss over the spillway face can be taken as 10% of the velocity head at the toe of the spillway. What kind of energy dissipating facility is to be selected? Answer: y₂ > y3 (4.33 m> 4 m) A suitable USBR-type stilling basin.
