Vegetation and large wood: Impacting hydrodynamics and transport from headwaters to the coast
Session ID#: 79783
Session Description:
Management of fluvial and coastal environments requires in-depth understanding of the interactions among vegetation, large wood, and hydrodynamics. Vegetation and large wood influence the transport of nutrients, pollutants, and sediment across a range of spatial scales: from individual plant stems altering local hydrodynamics to large patches of vegetation or log accumulations adjusting reach-scale hydraulics and channel and floodplain form. Flow and sedimentation characteristics also modulate vegetation distribution and succession, as well as wood storage and transport. Feedbacks among hydrologic and geomorphic processes, wood, and vegetation are fundamental drivers of ecological dynamics, providing physical habitat and nutrients to organisms. These interactions have unique effects in different landscapes, from headwaters to alluvial rivers and nearshore waters. This session seeks contributions that highlight the interactions among vegetation, large wood, and transport of water, sediment, and solutes using field techniques, numerical modeling, physical experiments, and/or remote sensing.
