Earth Surface Dynamics and related fields of research aim at understanding the physico-chemical processes that control the Earth’s surface evolution, establishing the different internal/external forcing and quantifying the particle and element fluxes over space and time. Numerous studies have demonstrated how climate forcing drives erosion processes and relief evolution in various environmental contexts. However, quantifying the impact of intrinsic climate variability on surface processes and landscape dynamics has remained difficult to assess since it implies different temporal and spatial scales. Understanding the geomorphic response to (1) anthropogenic climate and land-use change, (2) high-frequency climate variability (e.g. freeze-thaw cycles, monsoonal precipitation), (3) extreme climatic events (e.g. tropical cyclones, flood/debris flow events), and (4) long-term climate trends (e.g. Plio-Pleistocene glacial/interglacial cycles, Late-Pleistocene to Holocene climatic change) appears therefore of prime importance to better interpret erosional processes and sediment/element fluxes at the Earth’s surface.
This session aims at presenting original studies that quantify climatically-induced changes in surface processes, sediment production and landscape dynamics over different temporal and spatial scales. We welcome contributions including (but not limited to) remote-sensing, field investigations, surface-process modelling, geochemical tracers, sedimentary archives or other innovative tools.
