Study on the impact and adaptation strategies of climate change on infrastructure in coastal communities.

This study aims to explore the assessment of landslide hazards and adaptation faced by coastal communities under the impact of climate change. Considering the influence of climate change leading to increased frequency of extreme weather events, particularly heavy rainfall, which significantly affects the stability of hill slopes, this research will establish a shallow landslide susceptibility model for extreme rainfall events. This model can comprehensively solve the unsaturated transient Richard's equation and utilize the resultant pore water pressure along with the formula for the safety factor of unsaturated slope stability to construct a comprehensive regional landslide susceptibility analysis module. The module will generate distribution maps depicting the potential for slope collapses during extreme rainfall events. Through this analysis module, the study intends to predict collapse grids influenced by climate change and use Geographic Information Systems to create collapse susceptibility maps. We will overlay these maps with key infrastructure of coastal communities, including emergency response units, to understand the impact of landslide disasters on the infrastructure, emergency response capabilities during disasters, and post-disaster recovery capabilities of coastal communities. Furthermore, the study will explore the impact and adaptation strategies of climate change on infrastructure in coastal communities.
