The cross-section of a small river is sub-divided into seven segments of width 1.5 m each. The average depth, and velocity at different depths were measured during a field campaign at the middle of each segment width. The discharge computed by the velocity area method for the given data is _____ m3/s (round off to one decimal place).
| Segment | Average depth (D) (m) | Velocity (m/s) at 0.2D | Velocity (m/s) at 0.6D | Velocity (m/s) at 0.8D |
|---|---|---|---|---|
