After the first 2 hours, the initial backwater profile is changing, so an unscheduled flow change is introduced in the canal modifying some offtake flow, as shown in Table 8.
Initial and unscheduled offtake changes on test case 1-2
| Pool number . | Offtake initial flow (m3/s) . | Check initial flow (m3/s) . | Unscheduled offtake changes at 2 hours (m3/s) . | Check final flow (m3/s) . |
