2) DISCHARGE BY VELOCITY-AREA METHOD. At a certain section of e river the left and right water edges are 3.0 and 45.0 meters respec- tively 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 ere 0.15, 0.30, 0.4S, 0,50, 0.48, 0.55, 0.54, 0.48, and 0.20 meters per second, respectively. Determine the followings 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.

2) DISCHARGE BY VELOCITY-AREA METHOD. At a certain section of
e river the left and right water edges are 3.0 and 45.0 meters respec-
tively 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 me ters 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.
