Question
1. Describe at least one equation used to estimate the freeboard in an unlined, earthen channel. Make sure to provide a reference for the source of your equation. 2. You need to design a non-erodible, earthen channel having an ideal, stable cross-section. The bed slope should be 0.1%. The analysis of the soil provided the following information: pup = 2.65, dso = 6.5 mm, and an angle of repose of 30°. Establish the design dimensions for the following discharges: Q1 = 1.5 m/s and Q2 = 4 m/s.
