Advances in Computational Geosciences I

Submit an Abstract to this Session



Session ID#: 32042

Session Description:
This session highlights advances in the theory and practice of computational geoscience, from improvements in numerical methods to their application to outstanding problems in the Earth sciences. Common issues include robust and efficient solvers, multiscale discretizations, design of benchmark problems and standards for comparison. Increasing data and computational power necessitates open source scientific libraries and workflow automation for model setup, 3D feature connectivity, and data assimilation, and automation in uncertainty representation and propagation, optimal design of field studies, risk quantification, and testing the predictive power of numerical simulations. By bringing these crosscutting computational activities together in one session, we hope to sharpen our collective understanding of fundamental challenges, level of rigor, and opportunities for reusable implementations. Contributions from all areas are welcome, including, but not limited to, fault modeling, tectonics, subduction, seismology, magma dynamics, mantle convection, the core, as well as surface processes, hydrology, and cryosphere.
