This book presents and discusses the construction of mathematical models that describe
phenomena of flow and transport in porous media as encountered in civil and environmental
engineering petroleum and agricultural engineering as well as chemical and geothermal
engineering. The phenomena of transport of extensive quantities like mass of fluid phases
mass of chemical species dissolved in fluid phases momentum and energy of the solid matrix and
of fluid phases occupying the void space of porous medium domains are encountered in all these
disciplines. The book which can also serve as a text for courses on modeling in these
disciplines starts from first principles and focuses on the construction of well-posed
mathematical models that describe all these transport phenomena.
