(Dis)connectivity Across Processes and Landscapes
Session ID#: 251759
Session Description:
Connectivity is increasingly used as a framework for understanding water-mediated transport through the environment. In general, connectivity analyses aim to quantify or characterize the spatiotemporal patterns of material transport within and among landscape elements or identify how processes within landscapes are linked. In keeping with long-standing sessions at the General Assembly of the European Geosciences Union (EGU), we use the term (dis)connectivity to recognize the role of disruptions in connectivity (highly connected versus highly disconnected) and how transport is impacted. This session invites abstracts across the range of hydro-geomorphic disciplines that address fundamental questions using (dis)connectivity concepts or approaches. Examples include, but are not limited to, ecogeomorphic interactions controlling sediment transport among landscape components, channel floodplain connectivity in riverine and coastal environments, impacts of woody debris, surface-subsurface hydrological (dis)connectivity, network analyses of channel network structure and dynamics, process connectivity, and many more.
