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 1mm diameter.
A clay tile Vshaped 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
quasisteady 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...
