Interactions of Flow, Sediment, and Wood in River Ecosystems: Observations and Modeling
Session ID#: 160915
Session Description:
Large wood (LW) is a key component of river ecosystems. The presence of LW increases flow heterogeneity and alters bed morphology. LW transport may transiently affect the river system, in some cases leading to accumulation of wood pieces in LW jams which form, disassemble and re-form at natural obstructions and river infrastructure. LW jams may also be installed as river restoration interventions. Under some conditions, LW jams can create an upstream backwater of slower, deepened water, increasing nutrient uptake and ecological productivity, but also flood risk. A cross-disciplinary effort is required to improve our understanding of the complex interactions of flow, sediment, and wood in rivers and how these interactions affect secondary properties such as nutrient cycling, biological productivity, and hazards.
This session aims for a broad representation of the scientific communities focusing on hydraulic, ecological, geomorphic, and human aspects associated with LW in rivers. We invite presenters to share recent scientific advancements in our understanding of wood in rivers using field, laboratory, or numerical approaches.
