GM7.6Sedimentary source-to-sink fluxes and sediment budgets
|Convener: A. A. Beylich | Co-Conveners: F. Brardinoni , K. Laute|
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 patterns of weathering, erosion, transport and deposition of material (e.g., sediment, wood, nutrients, solutes, carbon) across landscape components. While it is a challenge to develop a better 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. Current knowledge on the sediment cascade within Holocene to contemporary climates forms the basis for predicting the consequences of future climate change. However, much of this information is 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. The session is open for contributions on sedimentary source-to-sink and sediment budget studies from small catchments to continental scales, from long-term to contemporary timescales. The integration of different methods and techniques of data collection (e.g., from field-based to remotely sensed) and analysis / modelling is welcome.
