Problem (Open Channel Flow) For a rectangular open channel, the discharge is expressed by the equation: $$Q=\frac{S^{\frac{1}{2}}(BH{)}^{\frac{5}{3}}}{n(B+2H{)}^{\frac{2}{3}}}$$ where B is the width, $$\mathrm{H}$$ is the depth of flow, $$\mathrm{S}$$ is the channel slope and $$\mathrm{n}$$ is the roughness coefficient. Determine the depth of flow $$\mathrm{H}$$ for the following parameters shown in Table 1. Use any of the 4 methods discussed to solve nonlinear equations. Round off answer to 3 decimal places.
