Water flows at 4 m3/s along a horizontal channel made of unfinished concrete (n=0.014). If the channel has a width of 2 m, and the water depth at the control section A is 0.9 m, approximate the depth at the section where x = 2 m from the control section. Use increments of Δd = 0.004 m and plot the profile for 0.884 m ≤ d ≤ 0.9 m.

Problem # 2 A discharge of 4800 m/s occurs in an approximately rectangular channel with a depth of 10 m and a width of 50 m. The channel slopes at a rate of 1/2000. The bed consists of fine sand (ds- 0.177 mm) and medium sand (ds-0.354 mm). Use the Shields diagram to determine whether these sizes will remain stationary or be transported. Assuming that the width and the slope do not change with the discharge, determine the discharge that...
