A discharge of 4.25 m3 /s occurs within a trapezoidal channel with a base width of 3m, 3:1 side slopes (i.e. Z = 3), a longitudinal bed slope of 0.0009 m/m with a Manning’s roughness coefficient of 0.025 (i.e. sand). State the normal flow depth (yn) critical flow depth (yc) and the Froude Number of the flowing water.
