SOPRA URNO DEBRIS FLOWS SIMULATION
Sopra Urno debris flow caused the largest number of casualtiesp gand damages, due to the fact that the flow crossed the village. The simulation shows a good capability of the model to
describe the debris run-out, in particular, in high zone ofslope.
In the urbanized area, differences are noted with path of thereal event, especially in lateral streets, but the result can beconsidered acceptableconsidered acceptable.
Comparison of simulated and real-event (Fig. 4) return avalue of fitness f = 0.74 (Table 2, case 2).
The maximum velocities reached by simulated flows (Fig. 5 y ( ga) are high, as expected, in the steeper areas, and decrease gradually at the outlet in downstream.
