Session ID#: 18089

Session Description:
This session explores computational models for earth-surface processes, and data sets that can be used to test them. Models for a wide variety of terrestrial systems, including geomorphic, hydrologic, biogeochemical, fluvial, sedimentary, eolian, cryospheric, ecologic, and morphotectonic, continue to advance in both explanatory power and sophistication. We welcome contributions that deal with the various facets of models and model-data comparison: creating and exploring new models and concepts, comparing models with data sets, new data sets that demand better models, community modeling projects that foster connection and collaboration, novel computational algorithms, new data that challenge current models, models that capture (or fail to capture) the essence of a particular pattern or phenomenon, models that explore a previously underappreciated process or feedback, and beyond. Especially encouraged are studies that examine the coupling between processes and/or domains, as enabled for example by advances such as the Community Surface Dynamics Modeling System’s model-coupling technology.
