Water flow in a river channel has velocity V = 5m/s, depth d = 2.5m, slope = 0.0008 and friction 0.012. The characteristic of the bed material has dimension ds = d50 = 0.63 mm. With the support of the design chart below, what is the flow velocity if we consider bed forms? (Consider friction f = 0.012 constant throughout the exercise; sediment density ps = 2600 kg/m³; water density p= 1000 kg/m³).
