This book highlights several methods and quantitative implementations of both probabilistic and
fuzzy-based approaches to uncertainty quantification and uncertainty propagation through
environmental subsurface pollution models with uncertain input parameters. The book focuses on
methods as well as applications in hydrogeology soil hydrology groundwater contamination and
related areas (e.g. corrosion of nuclear waste canisters). The methods are illustrated for a
broad spectrum of models from non-differential I O models to complex PDE solvers including a
novel 3D quasi-analytical model of contaminant transport and a site-specific computer model of
dissolved contaminant migration from a DNAPL (Dense Non Aqueous Phase Liquid) pollution source.
