Fig. 10. Simulation results on the travel distance of debris flow assuming the slope and channel system shown in Fig. 4a for (a) Case 1, (b) Case 2, and (c) Case 3 in Scenario 1. Each figure shows spread areas of the liquefied layer (cyan dots), saturated soil mass (blue dots), and unsaturated soil mass (black dots) at the time indicated by the number in each figure.
