Design a canal culvert 75 metres long to pass a normal full supply discharge of 4 m3/s with 0.3m head loss. The upstream and downstream canal parameters are as given in the following. Ymax=1.40 m Vmax=0.830 m/s

Ymin=1.05 m V min =0.74 m/s

At 5 m3/s, the normal upstream depth of flow = 1.28 m,

assume a square box section DxD is to be used with a rounded entrance so that K1=0.30. if R = D/4 for a single box section

Design a canal having a trapezoidal cross section to carry a design discharge of irrigation water of 900 cfs. The slope of the canal is to be 0.002. The canal is to be lined with concrete, and it is to have the best hydraulic section for the design flow. Adopt a Manning’s roughness coefficient ? for lined canals under (troweled concrete) ? = 0.012.

Design a trapezoidal channel to pass a discharge of 10m3/s and the channel will be excavated through rock by blasting. The topography in the area is such that a bottom slope of 1 in 4000 will be suitable. Assume that n = 0.030 and select a value for the side slope, Z, as 1 horizontal to 4 verticals. Sketch the diagram for all calculated dimensions.
