A channel has a triangular cross section with an apex angle of 90°. Draw the Q-y curve for a specified energy of 3.0 m. Determine the critical depth and the corresponding discharge.

Water flows in a rectangular channel at a rate of 250
/s. The depth of flow is 5 ft and the bed width is 10 ft. If the channel bed elevation is increased by 0.5 ft using a smooth step, what is the depth and type of flow at the raised section?
