Abstract

Mud and debris flows are hazardous events consisting of a mixture of water, soil, rocks, and organic material, which move rapidly down slopes or through river channels causing significant destruction to infrastructure, landscapes, human life and livestock. These flows often occur in areas prone to heavy rainfall, volcanic activity, or rapid snowmelt, leading to landslides. The latest example of such occurrence is at Wayand in India. Effective measures are essential to reduce the risk and mitigate damages. The measures require installation of early warning systems, engineering measures, land use planning, creating public awareness and education, flood plain management and continuous monitoring. Informatics provides numerous technologies to support these functions and activities. The paper discusses Mud and debris flows in the context of Wayanad Disaster (2024), use of FLOW-2D Software for simulating mudflows and debris flows, and provides recommendations for mitigation or prevention of such calamities with stress to Engineering measures.
