A wide channel is formed of two reaches. The first reach has a mild bed slope, while the second reach has a steep bed. The depth of flow at the point of change in the bed slope is 1.5 ft. Depths of flow in the first and second reaches are 1.8 ft and 0.6 ft, respectively. Find the discharge per unit width and the bed slope in the first and second reaches. The Manning roughness coefficient n = 0.016.
