The working group on Marine Natural Hazards is dedicated to the scientific investigation of marine natural hazards and their impacts to enhance the resilience of coastal areas. Our working group examines phenomena such as flash floods, long waves, and tsunamis to gain a better understanding of the underlying processes and their effects on human and natural systems (cities, ports, or coastal sections). By combining field investigations, numerical and experimental methods, we strive to protect communities from the growing threats of climate change.
