Conceptual Models for Environmental Engineering Related to Subsurface Flow and Transport

This chapter aims at providing an overview of research related to subsurface flow and transport modelling. We address the existing literature and discuss the role of modelling for engineering activities in the subsurface. For environmental applications, modelling is typically employed to quantify risk scenarios and corresponding uncertainties which arise from different origins. One source of uncertainty is, of course, the degree of abstraction that is applied to describe the relevant physics (or chemistry, if necessary) in a problem of interest.
