Scope
Flooding is the worlds most destructive and costly natural hazard, impacting nearly one billion people, with about 300 million affected annually and global losses surpassing 60 USD billion.
Global flood hazard is widely expected to worsen in the future. Climate change, with predictions of increased frequency of extreme rainfall events for many parts of the world, is seen as the key driver in changing flood risk. However, climate change is not the only component that can increase global flood hazard. There is an increasing recognition of the need to assess flood risk as a function of multiple environmental factors, including morphodynamic processes, floodplain connectivity, changes in inundation patterns, and sea level rise. Understanding the complex interactions between these factors is essential for predicting future flood hazards and mitigating their impacts.
This session invites contributions that explore the interactions between flooding and hydro-geomorphological processes. We aim to deepen the understanding of feedback mechanisms between climate, hydrology, and river morphodynamics, and their collective role in shaping future flood risks and alterations to floodplains. We are particularly interested in research that investigates how rivers respond to changes in hydrology, geomorphology, morphodynamics, and climate, and how these responses translate into variations in flood risk. 
We encourage submissions from interdisciplinary researchers employing experimental, numerical modelling, and field-based approaches to advance methodologies and generate new insights into the following themes:
Morphodynamic Processes in Flood Hazard Evolution
Human Impacts on Fluvial Systems and Flood Risk
The impacts of climate change on future trends in flood hazards.
Patterns and Drivers of Flooding and Morphological Shifts
