A Study on Simulating Landslides Using Unity Software
Abstract:
The main rivers in Taiwan present numerous distinct features, such as narrow catchment areas, short main flow paths, fast-flowing rapids, and steep slopes. In Taiwan, typhoon season in summer and fall is the period during which torrential rainfall frequently occurs. Large amounts of rainfall in short periods increase the likelihood of disasters, such as hillside collapses, landslides, and floods. By using a computer simulation to visually present landslide disasters, disaster evacuation can be facilitated and casualties can be reduced. In the present study, we compiled the causes of hillside landslides by employing a remote helicopter equipped with a camera to capture images of landslide-prone rivers and hillsides. ReCap computation was adopted to establish 3D river and hillside models for mesh optimization, which were then imported into the Unity software. Finally, by referencing slope and geographical data, and considering various landside factors such as cause, scale, flow direction, flow speed, and damage, model disaster scenarios were created to perform simulations. The results were uploaded to Web-and mobile-based platforms, providing a reference for assisting the general public in implementing preventive measures, thereby reducing the occurrence of disaster incidents.
