DISCHARGE BY VELOCITY-AREA METHOD. At a certain section of the river the left and right water edges are 3.0 and 45.0 meters respectively from an initial reference point. Verticals are located at distances 7.0, 12.0, 16.5, 19.5, 23.0, 27.0, 32.0, 35.0, and 39.5 meters from the initial point. Depths of Verticals are 1.8, 3.5, 4.6, 3.4, 5.8, 6.6, 5.7, 3.6, and 1.2 meters. Mean velocities in the verticals are 0.15, 0.30, 0.45, 0.50, 0.48, 0.55, 0.54, 0.48, and 0.20 meters per second, respectively. Determine the following:

a) Cross-sectional area of the river (sq m)

b) Discharge of the river (cu m/sec)

c) Average velocity of flow of the river (m/sec)

Sketch the cross section of the river. Assume that the discharge in the end zones to be negligible or zero.
