Climate change is fundamentally reshaping Earth’s surface by driving unprecedented increases in the frequency and magnitude of hydro-geomorphological and geological hazards. Flooding remains one of the deadliest and most costly natural hazards worldwide, with nearly one billion people exposed and approximately 300 million affected annually, resulting in global losses of around 60 billion US dollars per year. At the same time, landslides and other geohazards pose severe and growing threats, particularly in mountainous and densely populated regions, where they are commonly triggered by intense rainfall, seismic activity, volcanism, and human-induced landscape modifications.
While intensifying extreme rainfall is projected to substantially increase future flood hazard, climate forcing alone does not fully explain observed and emerging risk patterns. Morphodynamic processes, floodplain connectivity, changes in inundation frequency, and sea-level rise play fundamental roles in controlling flood behaviour and impacts. Similarly, geohazards arise from complex interactions among climate variability, land-use change, tectonic activity, and geological processes across diverse environments.
Recent advances in remote-sensing technologies, particularly Interferometric Synthetic Aperture Radar (InSAR) and Unmanned Aerial Vehicles (UAVs), have transformed the monitoring of ground deformation, slope movements, and terrain instability. These tools complement field observations, experimental approaches, and numerical modelling, enhancing our ability to detect, understand, and anticipate hazardous processes.
This session invites interdisciplinary contributions examining how rivers, hillslopes, and landscapes respond to hydrological, geomorphological, and climatic drivers, and how human interventions (including flood defences, managed floodplains, hard engineering, and land-use planning) amplify or mitigate hazard and risk. We particularly encourage studies addressing morphodynamic controls on flood hazard, climate-driven hazard trends across diverse environments, patterns and drivers of flooding and landslides, and innovative monitoring and modelling approaches that support resilience and sustainable decision-making in hazard-prone regions.
