MS3
Hybrid and Multiscale Modeling of Subsurface Flow and Transport Processes

9:50 AM - 11:50 AM
Room: Mesa C

Issues of scale are pivotal in advancing the scientific basis for quantitative simulation of subsurface flow and reactive transport. It is increasingly recognized that small (e.g., pore) scale processes significantly impact large (e.g., field) scale phenomena, particularly in the case of coupled flow/transport/reaction processes such as precipitation/dissolution or biogeochemical reactions. This session will address recent advances in coupling of models at different scales (multiscale modeling) and with different process representations (adaptive physics, hybrid modeling) and identify future directions for research.
