Biogeomorphology: conceptualising and quantifying processes, rates and feedbacks (co-organized) 
Convener: Annegret Larsen  | Co-conveners: Nico Bätz , Jana Eichel , William Nardin , Wietse van de Lageweg 
Session description:
Biota affect hydrology, sediment transport, weathering and soil formation over variable temporal and spatial scales and thereby influence, hillslope, fluvial, coastal, and aeolian landscape form and dynamics. In turn, geomorphological processes have large impacts on ecological processes by shaping topography and affecting water availability, which determines biological diversity and succession.
Understanding these feedbacks between biological and geomorphological processes is becoming increasingly important as new ‘building with nature’ projects emerge and also increasingly find its way into management (i.e. restoration projects). Despite some advances, the conceptualisation and quantification of the processes, rates and feedbacks between geomorphology and ecology are still limited, particularly in systems that are sensitive to human-induced or natural environmental change (e.g. high-mountain and polar environments, deserts, hillslopes, rivers and wetlands, salt marshes and deltas).
This session seeks contributions that are investigating biogeomorphology on all spatial and temporal scales, including experimental, field and computational/numerical modelling studies. We especially encourage interdisciplinary studies on river, and delta biogeomorphology, animal influences on geomorphic processes, chronologies of biogeomorphological change, and hillslope processes. Emphasis will be given to novel research on biogeomorphological feedbacks, on the quantification of feedbacks and associated rates, and the investigation of the resilience of coupled eco-geomorphic systems to human impact and climate change.
