This session examines deltas and estuaries from multiple points of view: morphodynamics, hydrodynamics, material cycling, ecosystem, human impacts, and sustainability. We invite contributions that advance research on deltas and estuaries as complex river-mouth systems from both modern and ancient examples, and that develop integrated frameworks for modeling delta & estuary dynamics on a broad range of temporal and spatial scales: from studies of coastal evolution over the Quaternary to small-scale sediment/material transport processes. We also invite physical processes studies based on field observations, numerical simulation, and flume experiments. Finally, the conveners encourage contributions that promote data collection and sharing for both advancing science and local problem solving, that consider policy and governance issues linked to the sustainable development of deltas and estuaries, and that use in-situ and satellite data for modeling and risk assessment.
