ABSTRACT
The modeling of transport in porous media continues to be an important and challenging problem with applications in groundwater pollution, bioremediation of soils, petroleum engineering, food science engineering, drug delivery systems, and blood flow in tissues to name a few. Over the past several decades the need for a multidisciplinary approach to this problem has been recognized and collaborative work is becoming the rule rather than the exception. A combination of hydrologists, mathematicians, chemists, microbiologists, engineers, and physicists is needed to maintain progress in the modeling and prediction of flow and transport in porous media for both nonreactive and reactive solutes. This chapter focuses on the nonreactive case while the subsequent chapter examines the reactive case.
