EP32B:
Ecogeomorphology: Sediment-Biota Feedbacks that Shape Land and Seascape I

Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.
You can still search the program to see your colleague�s abstract submissions as well as the sessions submitted for the 2016 Fall Meeting. The final program will be released in early October.


Session ID#: 17719

Session Description:
Recent studies have highlighted the importance of ecogeomorphic feedbacks in a variety of environmental settings, including marshes, tidal channels, deltas, rivers, aeolian dunes, and many others, and these feedbacks often lead to the formation of complex morphological patterns. Interactions between flow, sediments, and biota occur at a range of spatial scales, ranging from millimeters to kilometers. This session explores such ecogeomorphic feedbacks, focusing on large-scale landscape evolution. We welcome studies of ecomorphodynamics for both flora and fauna using field studies, numerical models, and/or laboratory experiments.
