Figure 9. Typical simulated results are visualized in TDBSim. The result is rendered at (a) t=100s; (b) t=300s; (c) t=1000s; and (d) t=2400. A – location of rail network. B – location of small community. C – location of Parque da Cachoeira. D – location of Paraopeba river. The base map is the satellite image (Sentinel S2). The color map of the simulation results is mapped by velocity characteristics.
