Ecohydraulics and Ecomorphodynamics: Biophysical Interactions Across Scales in Natural and Engineered Aquatic Systems
Session ID#: 158495
Session Description:
Rivers, estuaries, and coastal areas are naturally dynamic systems, characterized by a suite of biophysical processes that are subject to exogenous disturbance. The need to understand interactions among hydraulic, ecological, and geomorphic processes in natural and managed systems has become urgent for societies whose waters are undergoing changes associated with land use, water management, and climate change. This session focuses on the science and management of riverine, coastal, and estuarine ecohydraulics and the impacts of change. Topics may include: 1) hydrodynamics and geomorphic impacts of vegetation, 2) organism-habitat interactions, 3) ecosystem engineers, 4) flow-biota interactions on nutrient and pollutant transport, 5) disturbances in processes, form, and ecosystem structure/function. We encourage submissions addressing the challenge of transferring information across scales. In light of current efforts prioritizing infrastructure renewal, we invite presentations that examine the role of natural infrastructure (floodplains, mangroves, reefs) as a key component of hazard protection and climate resilience.
