A trapezoidal cross section with bank slopes of 1:1 and a bottom width of B = 91.45 m contains a bed material gradation as shown table, which has diameters of D₃₅ = 0.28 mm, D₄₀ = 0.30 mm, D₅₀ = 0.32 mm, D₆₅ = 0.38 mm, and D₉₀ = 0.47 mm. The flow depth is 1.02 m in river, and bed slope is I_o = 0.0007. The specific gravity of this particle is s = 2.65. Take kinematic viscosity as n =10^-6 m²/s and density of water as r = 1000 kg/m³. Take b=1 and k=0.4.
