International Working Group on Reactive Transport

Reactive transport as a research focus has surged in recent years, although as a recognized academic discipline within the Earth and environmental sciences it continues to languish, perhaps because it is a multi-disciplinary topic that falls between the cracks of the legacy fields of geochemistry, hydrology, and engineering.  The multi-disciplinary field of reactive transport (RT) was inaugurated 20 years ago with the publication of Reviews in Mineralogy and Geochemistry 34: Reactive Transport in Porous Media. RT principles have expanded beyond early applications largely based in contaminant hydrology to become broadly utilized throughout the Earth and environmental sciences.  RT is now employed to address a wide variety of natural and engineered systems across diverse spatial and temporal scales, in tandem with advances in computational capability, quantitative imaging and reactive interface characterization techniques.  This breadth of application demonstrates an increasing recognition among the Earth and environmental science community of the balance between chemical reactivity and transport of (multiple) phases and the coupled nature of these processes in the terrestrial environment.  Within the RT discipline, reactive transport modeling certainly plays a prominent role, since it has shown to be an essential tool for the analysis of coupled physical, chemical, and biological processes in Earth systems, and has the additional potential to integrate the results from fundamental research.  Using a modern reactive transport approach, it is possible to provide predictive capabilities for Earth and environmental systems that go well beyond the empirical models in wide use today.

2-5 Oct. 2017. Reactive Transport in the Earth and Environmental Sciences for the 21st Century (Amboise, France)

Organizers: Christophe Tournassat, Carl Steefel & Jennifer Druhan with the great help of Valérie Deplanque & Sara Hefty

The RT-Amboise workshop is dedicated to current developments and future directions in reactive transport as applied to natural and engineered systems in the Earth and environmental sciences. The principal purpose of this meeting was to inaugurate a series of international workshops on reactive transport that will review the state of the art and future directions in the field on a regular basis every two years. An additional purpose was the development of chapters and identification of authors and topics for a new volume in the Reviews in Mineralogy and Geochemistry (RiMG) series, which will serve as an update to the 1996 volume on the same topic.
