Approaches for hydrometeorological cascading hazard assessment 

Maria Isabel Arango, PhD Student at the University of Potsdam, presents her talk "Approaches for hydrometeorological cascading hazard assessment: A case study in the tropical region of the northern Andes in Colombia".
Abstract: In recent decades, tropical mountain regions have experienced devastating disasters caused by a series of hazards, including landslides, debris flows, and floods. While there are effective hazard assessment methodologies in place for each of these hazards individually, there is still a significant gap in our understanding and evaluation of multi-hazards. The complex interactions of these various processes in time and space can result in amplified and widespread damage. Despite the challenges, evaluating cascading multi-hazards is a crucial step towards reducing disaster risks and managing urbanization to reduce exposition.
In this presentation, we will examine various methodologies for assessing hydrometeorological hazards in complex, multi-hazard situations. Additionally, we will explore a case study that demonstrates how cascading hazard assessment can be performed using several physically-based models in succession, while accounting for the interrelationships between different hazards. This adaptable methodology provides users with significant control over its implementation, and can be employed in a variety of environments with varying levels of data quality and quantity.
