A wide canal has a bed slope of 0.001 and carries water at a normal depth of 1.2 m. A weir is tobe constructed at one point to increase the depth of flow to 2.4m. a) How far upstream of the weir will the depth be 1.35 m? Take Manning roughnesscoefficient as 0.018. What is the water surface profile and why?b) Instead of the weir a free overfall is constructed. Where upstream of the free overfall 98%of the normal depth occurs? What is the water surface profile and why?c) In case of (b) where the EXACT normal depth occurs? (5 Marks)
