Reactive Transport Modelling I

This short course will review the unifying concepts and mathematical models underlying the quantitative description of reactive transport systems. We will focus on the coupling of biogeochemical reactions to transport processes in near-surface environments (e.g. soils, sediments, tailings ponds, and shallow aquifer). Examples will range from simple “back of the envelope” mass balance calculations to advanced numerical simulations. Students will learn how to assemble the building blocks of a reactive transport model (RTM). Particular attention will be given to the formulation of biogeochemical reaction networks, the kinetics of abiotic and biotic redox processes, mixed kinetic-equilibrium models, parameter calibration, numerical errors and simulation scenarios. Depending on the participants’ interests, we will also cover one more or advanced topics, such as bioenergetic controls, genome-enabled RTMs and dual-porosity media. The short course will provide students with the foundation to become informed users of existing reactive transport codes, for example MIN3P. The short course is designed for graduate students and postdocs with a background in environmental geochemistry, and a working knowledge of transport processes and partial differential equations. Enrollment is limited to 10 participants.
