306 Symposium--Reactive Transport Modeling In Soils: II

Until recently, research and modeling efforts have generally focused on improving our understanding of physical transport processes associated with solute movement at the field scale while much less attention has been placed on the interrelated biological and geochemical reactions that impact solute partitioning. The Reactive Transport Modeling in Soils symposium, will address the state-of-the-art and future research needs with respect to the development and parameterization of reactive transport models for describing the fate and transport of nutrients and contaminants in chemically and physically heterogeneous soil systems.
