Probing and modeling reactive transport processes in Earth systems

Session ID#: 80976

Session Description:
The dynamic evolution of many Earth systems are shaped by continuous mass transfer within the system and across interfaces, which is largely controlled by the interplay between different transport mechanisms and a variety of biogeochemical reactions. Probing these coupled, i.e. reactive transport, processes and building predictive modeling capability are crucial for knowledge advancement in disciplines that include hydrology, biogeosciences, and geochemistry. For example, reactive transport processes triggered and accelerated by human activities play an increasingly important role in influencing groundwater migration and quality and nutrient cycling, and over geological time, naturally occurring reactive transport processes control the evolution of hydrothermal systems, mineral deposition and etc.

This session aims to bring together researchers across disciplines for a dynamic discussion of the progresses in probing and modeling reactive transport processes across scales over the past decades, and future research needs on experiments, observations, modeling, and data and modeling synthesis.
