The carbon cycle lies at the heart of Earth System Science, providing the key energetic link between terrestrial, ocean and atmospheric systems. Quantifying carbon fluxes, sinks and stores related to soils and sediments, and understanding the nature of interactions and feedbacks between carbon and sediments are essential to climate change research and management of carbon fluxes.

The fluvial system connects the soil erosion derived carbon fluxes with the oceanic carbon stores. Yet, these temporal patterns of the lateral carbon fluxes and their consequences for stocks are poorly understood at time scales greater than a few years. Furthermore, the spatial pattern of carbon storage and release at the catchment scale is not well known. The proposed session tries to present the state of the art of currents research on sediment and carbon fluxes under human impact and climate changes.

Invited keynote speakers are:

- Kristof van Oost
- Rolf Aalto
- Jed Kaplan and
- Simon Mudd

We invite contributions from biogeochemical sciences, soil sciences and geomorphology that explore relationships between geomorphic processes (including hillslope and fluvial processes) and the carbon flux at different spatial and temporal scales. We welcome contributions using physical or numerical modelling as well as field-based research.
