Along a certain range of a river, the right and left water edges (RWE & LWE) are 4.70 m and 60.80 m respectively from an initial reference point. The distances of each vertical from the reference point, the depth of each vertical, and the mean velocity in the vertical are given in the accompanying tabulation. Sketch the cross-section of the river using separate page, determine the discharge (cu. m./sec), and the average velocity of flow (m/sec). Assume that the discharge in the two end zones to be zero or negligible. Use mid-section method.

Transcribed Image Text:Along a certain range of a river, the right and left water edges (RWE & LWE) are 4.70 m and
60.80 m respectively from an initial reference point. The distances of each vertical from the
reference point, the depth of each vertical, and the mean velocity in the vertical are given
in the accompanying tabulation. Sketch the cross-section of the river using separate page,
determine the discharge (cu. m./sec), and the average velocity of flow (m/sec). Assume that
the discharge in the two end zones to be zero or negligible. Use mid-section method.
