Water flows in a trapezoidal channel in which the bottom width is 3 m and the side slopes are 2:1 (H:V). The channel lining has an estimated Manning n of 0.02, and the longitudinal slope of the channel is 0.1%. If the flow rate is 150 m³/s and the depth of flow at a gaging station is 4 m, classify the water-surface profile, state whether the depth increases or decreases in the downstream direction, and calculate the slope of the water surface at the gaging station.
