Abstract:

We are conducting study on the devastating record-breaking rainfall-induced disasters that occurred in central and eastern Nepal, particularly in the Kathmandu Valley and surrounding districts, in September 2024. This catastrophic event, triggered by an extreme three-day rainfall, caused widespread floods, landslides, and significant damage to critical infrastructure, agriculture, and urban settlements, with severe socioeconomic consequences.

Our research aims to analyze the geotechnical and hydrological factors contributing to these disasters, with a specific focus on the affected areas of the Kathmandu Valley, Kavrepalanchok, and Lalitpur. To enhance our understanding, our team conducted multiple reconnaissance site visits immediately after the event to assess flood and landslide damage, debris flows, and structural failures. These field observations were supported by the use of drones, cameras, and in-depth interviews with local communities.

Through this study, we aim to identify the mechanisms behind these disasters, evaluate the impact of human activities such as unregulated construction and mining, and propose measures for effective disaster risk management and infrastructure resilience. Our findings will also contribute to improving predictive models, informing urban planning, and designing geotechnical solutions to mitigate similar hazards in the future.
