CP11A:
Nearshore Processes I
Session ID#: 92955
Session Description:
The nearshore region is the transition zone from land to the open ocean. This region spans drastically different dynamical regimes with varying roles of waves, wind, tides, buoyancy, and morphology. The vulnerability of the coast to sea level rise, extreme storms, and anthropogenic influences is a major societal concern. Abstracts focusing on physical processes occurring in the nearshore region from the subaerial beach to the shelf break are invited. Interesting topics include: 1) surface and internal wave dynamics, 2) wind-, wave-, and tide-driven circulation, 3) extreme events in nearshore and river integrated systems, 4) mixing and turbulence, 5) cross-shelf exchange, 6) sediment transport and morphologic evolution, 7) process-based ecological or biological nearshore interactions. We welcome abstracts describing field observations (both remotely sensed and in-situ), numerical and laboratory modeling, theoretical analysis, and model-data assimilation. The nearshore processes session is an established and well-attended session in which student participation is strongly encouraged.
