1. Determine the flowrate per unit width, q, over a broad-crested weir that is 2.0 m tall if the head, H, is 0.50 m.
2. Water flows under a sluice gate in a 60-ft-wide finished concrete channel as is shown in Fig. P10.119. Determine the flowrate. If the slope of the channel is 2.5 ft/200 ft, will the water depth increase or decrease downstream of the gate? Assume Cc = y2/a 0.65. Explain.
