Aquatic ecosystems, from rivers to lakes, estuaries, and coasts, are naturally dynamic systems shaped and characterized by biophysical processes. Understanding interactions among hydraulic, ecological, and geomorphic processes in natural and managed fluvial/coastal environments has become urgent for balancing societal water resource needs in a changing climate. This session focuses on the ecohydraulics and ecomorphodynamics of riverine, estuarine, and coastal systems across various geographic regions to inform science and management efforts. We invite presentations on topics including, but not limited to, fluvial/coastal hydrodynamics and geomorphic impacts of vegetation; organism-habitat interactions; ecosystem restoration; flow-biota interactions on nutrient, sediment, and pollutant transport; ecosystem response to natural and anthropogenic disturbances; and natural infrastructure as a critical component of hazard mitigation and climate resilience. We encourage submissions that bridge spatial and temporal scales, promote integration across field, numerical, and laboratory approaches, and foster interdisciplinary collaboration and knowledge exchange in the spirit of “Where Science Connects”.
