A trapezoidal channel has a $3m$ bottom width and a $1$:$1$ side slope. It carries a discharge of $10\frac{m^3}{s}$ at a slope of $12c\frac{m}{k}m.$ A hydraulic jump forms at an upstream depth of $0\mathrm{.}6m.$ Calculate the specific momentum function, the critical flow depth and the conjugate depth. If you place baffle blocks to induce the hydraulic jump where the upstream depth is $0\mathrm{.}4m$ and the flow depth downstream of the baffles is $1\mathrm{.}2m,$ what is the force on the baffle blocks? $[$ hint: did you properly locate the center of pressure?$]$
