Question
Transcribed Image Text:At a certain section of a 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 in square meters
b. Discharge of river in cubic meters/sec
C. Average velocity of the flow of the river in meter/sec
