Landslide Susceptibility and Resilience Changing Climate– for the Case in Taiwan

Due to the impact of climate change, the increasing frequency of extreme rainfall events, with concentrated rainfalls, commonly cause landslide hazard in the mountain areas of Taiwan. The extraordinary rainfall behavior is critical for the landslide hazard, therefore, it certainly affects the landslide resilience as well.

This study employs rainfall frequency analysis together with the atmospheric general circulation model (AGCM) downscaling estimation to understand the temporal rainfall trends, distributions, and intensities in the adopted study area in Central Taiwan. Beside the landslide susceptibility, the landslide resilience was quantitatively defined and analyzed. The upstreams of Tachia River, Wu River, and Chuoshui River were adopted as the study area. The results of predictive landslide susceptibility and resilience analysis can be applied for risk prevention and management in the study area.
