Introduction

Natural hazard and disaster management is a critical field focused on understanding, mitigating, and responding to the impacts of natural events such as snow avalanches and floods. Effective management involves a comprehensive approach that includes risk assessment, preparedness, early warning systems, and emergency response strategies.

Snow avalanches, characterised by rapid flows of snow down a slope, pose significant threats in mountainous regions, necessitating advanced forecasting, infrastructure resilience, and public awareness to minimize risks.

Similarly, floods, which result from excessive rainfall, river overflow, or coastal storms, require robust floodplain management, infrastructure design, and community preparedness plans to reduce vulnerability and enhance recovery. Integrating scientific research, technology, and community engagement, disaster management aims to safeguard lives, property, and ecosystems, ensuring resilience against these dynamic natural hazards.
