T33E:
State of the Art in Computational Geoscience II Posters


Session ID#: 10784

Session Description:
This session highlights advances in the theory and practice of computational geoscience, from improvements in numerical methods to automation of tasks necessary to rigorously close the loop from data to decisions.  We welcome contributions from all areas of geoscience including, but not limited to computational tectonics, surface processes, hydrology, cryosphere, mantle, and core, addressing computational issues such as robust and efficient solvers, multiscale discretizations, design of benchmark problems and standards for comparison, open source scientific libraries, workflow automation for model setup and data assimilation, representation and propagation of uncertainty, optimal design of field studies, quantifying risk in decision problems, and testing the predictive power of numerical simulation.

By bringing these crosscutting computational activities together in one session, we hope to sharpen our collective understanding of the fundamental challenges, level of rigor, and opportunities for reusable implementations.
