Past Changes in Fluvial Systems, Floodplains and Estuaries
Convenors
Thomas Hoffmann, Onkar S. Chauhan, Peter Gell, Rajiv Sinha
Description
Fluvial systems are the major dispersal agents of water, sediment and nutrients from the continents to the ocean and have sustained civilizations for more than 5000 years. Unraveling past changes of fluvial and lacustrine processes in response to tectonics, climate, and land use change is a key area of research in fluvial geomorphology and paleolimnology.
Major themes of this session include:
-Methodologies to investigate floodplain response to environmental change at different spatial and temporal scales using alluvial, limnic and estuarine records.
-Reconstruction of fluvial dynamics and its impact on coastal systems in response to external perturbations.
-Cause-effect relationship between environmental change and floodplain development, scale-dependency of fluvial processes and their importance for buffered and delayed fluvial and lacustrine response.
-Connectivity structure of channel networks and sediment fluxes – implications for biogeochemical (e.g. C, N, and P) cycles and sediment infilling.
-Interactions of river morphology, hydrology and ecology and their implications for river and wetland restoration, and ecosystem services.
