Water flows over a spillway into a rectangular channel forming a hydraulic jump in order to dissipate mechanical energy. The spillway and the settling basin are $20m$ wide. Before the jump the water has depth of $1m$ and a velocity of $18\frac{m}{s}.$ Slope of channel bed $=0\mathrm{.}0012$ and $n=0\mathrm{.}012.$ Determine the depth after the jump
