A wide rectangular river with a bed slope of

carries a specific discharge of 3.6
/s/m. A dam is built across the river at which the affiux is found to be 1.0 m. Using the numerical integration method, estimate the water depth at a distance of 500 m upstream of the dam. Take the Manning roughness coefficient as 0.025.
