Reactive Transport Modeling

Monday, April 12, 2010: 1:30 p.m.-3:30 p.m.
Continental A (Westin Tabor Center, Denver)
Over the past few years reactive transport modeling has made a successful transition from a pure research instrument to a tool that is also increasingly used by practitioners. This session includes abstracts on: • Field-scale applications of reactive transport models of varying complexity from both practitioners and scientists.
Henning Prommer, Ph.D. , Vincent Post, Ph.D. and Rui Ma, Ph.D.
