EP32C:
Erosion and Sediment Transport in Steep Landscapes 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#: 17728

Session Description:
Steep landscapes dominate the topographic expression of actively uplifting mountain ranges, are subject to rapid bedrock erosion, and are the primary source of sediment to basins. However, much of the framework developed for quantifying the production and transport of sediment across landscapes is incompatible with rocky hillslopes, boulder-mantled streams, waterfalls, and other elements common to steep landscapes. This session aims to highlight work tackling erosion and sediment transport in these regions. For example: non-local hillslope processes, waterfall processes, coastal cliff retreat, alpine glacier erosion, and sediment transport in steep channels. We welcome submissions that incorporate field, experimental, theoretical, or modeling approaches.
