A wide rectangular channel under a bed slope of 14 X

carries a specific discharge of3.6
/s. An affiux of 1.0 m is measured at a dam located downstream of the river. Determine the distance upstream of the dam where the water depth is 2.2 m. Use the direct step method.

A wide river having a bed slope of 20 cm/km conveys a specific discharge of 4.1

/s. A dam is built across the river where the afflux at the dam site is 1.55 m. The Chezy roughness coefficient is 45 (metric). Find the length of the backwater curve.
