A rectangular channel 2.0 m wide has a discharge of 0.350 cms. Find the height of a rectangular weir spanning the full width of the channel that can be used to pass this discharge while maintaining an upstream depth of 0.850 m. if a contracted rectangular weir of length 1.5 m and height 0.6 m is used what would be the depth of flow upstream of the weir?
