Scope of the Summerschool

Migration of solutes, nanoparticles, and colloids in the subsurface is affected by a multitude of complex, interactive physical, geochemical and microbiological processes. Simulation of these processes requires knowledge of physical processes of partially-saturated water flow and convective-dispersive solute transport with a range of biogeochemical processes. Computational modeling is an extremely valuable tool for analyzing such complex problems.

Upscaling from pore to core

For understanding reactive transport process in complex porous media, it is crucial to identify and understand flow and transport processes at the microscopic (pore) scale, and then try to describe their manifestation at the continuum (core and field) scale. A powerful approach for transferring pore-scale information to the larger scale, and establishing relationships among the scales, is pore-scal4e modeling. Using pore-scale modeling, one can simulate flow and transport in detail by explicitly modeling mass transfer across interfaces and mass fluxes through pores. Micro-scale hydrodynamic and reactive processes can be explicitly modeled in detail and their effects at the larger scale quantified.

In this course

This course is designed to familiarize participants with the principles and numerical analyses of partially-saturated flow and coupled multi-component reactive transport, as well as application of state-of-the-art numerical codes at both the pore and continuum scales. Applications to solute transport, virus and colloid transport, and biodegradation will be discussed in detail. Although participants should have a general background in the principles of subsurface hydrology, the course gives an introduction to some theoretical aspects of water flow, solute transport. Hands-on computer sessions will familiarize participants with the basic use of the software packages.
