H089:
Multiscale, multifidelety, and hybrid machine-learning methods for flow and transport in hydrologic systems





Session ID#: 24628

Session Description:
Again and again we find that effective flow and transport equations fail to accurately describe observations, across hydrologic systems. This includes multiphase processes and reactive transport in complex flows, including porous media, streams, rivers and beyond. To deal with shortcomings novel approaches based on multiscale methods, meso-scale models, and hybrid data-driven methods have emerged as alternatives to standard models. This session is devoted to advances in such methods. General topics of interest include, but are not limited to :

- hybrid methods describing processes on different scales in different parts of computational domains;

- multiscale methods using innovative computational closures;

- mesoscale methods, including generalized random walks;

- multiscale finite-volume and finite element methods;

- Gaussian Processes, Deep Neural Nets;

- other methods bridging gaps between data and models at different scales. 

We seek applications to subsurface contaminant migration, bioremediation, multiphase flows, hyporheic exchange and any related topics.
