Fluvial systems cover a large portion of the Earth's surface, conveying water, sediment, and wood from headwaters to the sea. The routing of these materials through channel networks, from mountain streams to lowland rivers, drives complex process–form interactions and morphodynamic feedbacks. As a result, river morphology is inherently dynamic, shaped by the interplay of unsteady controlling factors. Extreme climatic events such as floods and droughts, as well as human interventions, can alter such factors and trigger complex morphological adjustments. Improving our understanding of river responses to disturbances is therefore essential not only for advancing fundamental scientific knowledge, but also for supporting sustainable river management, flood hazard assessment, and effective restoration strategies. This session aims to bring together geoscientists who use field observations, monitoring, remote sensing, and modelling approaches to address a range of issues, such as: (i) sediment and wood transport processes and fluvial morphodynamics; (ii) assessment and prediction of fluvial processes driven by climate extremes; (iii) river evolutionary trajectories in response to climate change and human pressures; (iv) assessment and monitoring of hydromorphological quality; (v) river and catchment management and restoration that seek win–win solutions for geomorphic hazard reduction and improvement of fluvial environment and processes.
