If the slope of the channel in Fig. P10.17 is 1 900 and n 0.014, determine the maximum water depth to keep from eroding particles of 1-mm diameter. A clay tile V-shaped channel, with an included angle of 90°, is 1 km long and is laid out on a 1 400 slope. When running at a depth of 2 m, the upstream end is suddenly closed while the lower end continues to drain. Assuming quasi-steady normal discharge, find the time for the channel depth to drop to 20 cm. A storm drain has the cross section shown in Fig. P10.31 and is laid on a slope of 1.5 m/km. If it is constructed of brickwork, find the normal discharge when it is exactly half full of...
