This research paper focuses on the heightened Nepal landslide risks in mountainous areas due to extreme precipitation induced by climate change. These landslides have increasingly affected vital road infrastructure, crucial for urban economies and rural communities.
The study employs advanced models to project future extreme rainfall patterns, developing high-resolution landslide hazard assessments using a weighted index approach.
By integrating various factors like terrain, soil, distance parameters, land use, and climate conditions, the study generates detailed landslide hazard models. Demonstrative case studies for Bagmati and Madhesh provinces validate the models with an 81-86% accuracy.
The study assesses road vulnerability in various climates, showing increased landslide risk in the future compared to the present.
