Reactive Transport: Model Formulation and Problem Application - Part I of II

10:30 AM-12:30 PM
Room: Ballroom B

Reactive transport modeling is playing an increasingly important role in many scientific and engineering studies in the geosciences. Increased resolution in spatial and process detail has paralleled the steady but steep rise in computational performance over the last 5 years. This minisymposium focuses on recent developments in algorithm design, computational methods, and model formulation that have made sophisticated modeling analyses possible. The session will highlight problem characteristics, numerical approaches to address these characteristics, and application of these approaches to important environmental problems.

Organizers: Steve Yabusaki
Pacific Northwest National Laboratory
Steve Bryant
University of Texas, Austin
