Climate change and human activities affect Earth surface systems, for example, via alteration of vegetation cover and frost penetration / duration in the ground. These changes in turn are likely to influence existing patterns of weathering, erosion, transport and deposition of material (e.g., sediment, wood, nutrients, solutes, carbon) across landscape components. While it is a challange to develop an improved understanding of how such changes interact and affect sedimentary source-to-sink fluxes and budgets, such quantitative analyses promise to be an efficient framework to assess the impact of environmental changes to sediment dynamics and evaluate landscape sensitivity. Our current knowledge on the sediment cascade within Holocene to contemporary climates forms the basis for predicting the consequences of ongoing and future climate change. However, much of our information is still limited in terms of spatial and temporal coverage and needs to be extended and consolidated. Only after coordinated research efforts and integration of regional datasets it is advisable to apply and test, with an acceptable degree of reliability, models of landscape response to climate change and anthropogenic impacts. This session invites contributions on sedimentary source-to-sink and sediment budget studies from small headwater systems to continental scales, and from long-term to contemporary timescales. The application and integration of different methods and techniques of data collection, e.g., from field-based to remotely sensed and analysis / modelling are welcome.
