The White River in Vermont (USA) has a rectangular channel cross-section with a Manning coefficient is n = 0.040 and the downstream bed slope is S = 5.0 × 10-5. In the summer, the width of the river and the center water depth are, respectively, 9.8 m and 1.2 m.
a) In that season, what are the hydraulic radius of the river, its mean velocity and volumetric discharge?
