A rectangular channel 2 m wide carries 3 m3 /s of water at a depth of 1.2 m. If an obstruction 40 cm wide is placed in the middle of this channel, find the elevation of the water surface at the constriction (Note that Q remains unchanged but q changes). What is the minimum width of the constriction that will not cause a rise in the water surface upstream?
