Table 1 HEC-RAS simulated peak flow rates and water depths under different dam failure scenarios in Derna
From: How extreme rainfall and failing dams unleashed the Derna flood disaster
Scenarios | Flow rate (m3s−1), Point A | Depth (m), Point A | Depth (m), Point B | |
|---|---|---|---|---|
1 | Bu Mansour dam fails first and washes out Al-Bilad | 17,600 | 17.6 | 7.3 |
2 | Al-Bilad breached ahead of Bu Mansour | 16,100 | 16.8 | 6.9 |
3 | Both dams overtop but do not fail | 4720 | 9.4 | 1.1 |
4 | The dams did not exist | 4800 | 10.4 | 1.3 |
