Furrow friction flow
WebThe flow depth at the approach section is y = 0.70 + 0.77 = 1.47 m. The top width of the flow at this section is T = b + 2 my = 1.2 + 2 (2.0) (1.47) = 7.08 m. Thus the average channel width becomes B = (b + T)/ 2 = (1.20 + 7.08)/ 2 = 4.14 m. We will use Equation 6.4 to determine the discharge.
