Book Description
This book presents, in an accessible and self-consistent way, the theory of diffusion in random velocity fields, together with robust numerical simulation approaches. The focus is on transport processes in natural porous media, with applications to contaminant transport in groundwater. Starting from basic information on stochastic processes, more challenging issues are subsequently addressed, such as the correlation structure of the diffusion process in random fields, the relation between memory effects and ergodic properties, derivation and parameterizations of evolution equations for probability densities, and the relation between measurements and spatio-temporal upscaling. Written for readers with a background in applied mathematics, engineering, physics or geophysics, the book offers an essential basis for further research in the stochastic modeling of groundwater systems.

Book Description
This research project investigated the coupled effects of uncertain contaminant source morphology (organic immiscible liquids distribution and composition) and aquifer properties on predicting solute transport in saturated groundwater systems contaminated with residual Organic Immiscible Liquids (OIL's). Research efforts focused on the development of multiple stochastic inverse models for characterizing contaminant fluxes in the near field and for characterizing NAPL distributions within source. In addition, work was conducted on the forward stochastic modeling, that is, to evaluate individual and collective impacts of uncertain spatially and temporally variable source morphological characteristics on subsurface solute transport predictions. The study also involved 1-, 2-, and 3-dimensional experimental efforts to study bench-scale and intermediate-scale uncertainties associate with OIL sources. These studies focused on describing dissolution from multi-component OIL's at varying residual fluid saturations and distributions, and the characterization of OIL sources using partitioning and interfacial tracers. As a final component of the project, the various stochastic models developed were evaluated using data from the pilot-scale field experiments conducted at Hill AFB, Columbus AFB, and Base Borden, Ontario, Canada. Data derived from partitioning/interfacial tracers and far-field dissolved OIL component distributions were used with the stochastic models to characterize OIL sources at each site.

Book Description
In many parts of the world, groundwater resources are under increasing threat from growing demands, wasteful use, and contamination. To face the challenge, good planning and management practices are needed. A key to the management of groundwater is the ability to model the movement of fluids and contaminants in the subsurface. The purpose of this book is to construct conceptual and mathematical models that can provide the information required for making decisions associated with the management of groundwater resources, and the remediation of contaminated aquifers. The basic approach of this book is to accurately describe the underlying physics of groundwater flow and solute transport in heterogeneous porous media, starting at the microscopic level, and to rigorously derive their mathematical representation at the macroscopic levels. The well-posed, macroscopic mathematical models are formulated for saturated, single phase flow, as well as for unsaturated and multiphase flow, and for the transport of single and multiple chemical species. Numerical models are presented and computer codes are reviewed, as tools for solving the models. The problem of seawater intrusion into coastal aquifers is examined and modeled. The issues of uncertainty in model input data and output are addressed. The book concludes with a chapter on the management of groundwater resources. Although one of the main objectives of this book is to construct mathematical models, the amount of mathematics required is kept minimal.

Book Description
Launches a series that intends to deal with topics as varied as atmospheric dynamics, coastal oceanography, subsurface flow and transport, lava flow, oil spills on the sea surface, indoor contamination and clean-room technology, risk assessment, data acquisition, and stochastic models. Introduces the general principles of diffusion in the subsurface environment and discusses the implications for the fate and transport of contaminants in the soils and groundwater. Emphasizes sorption and desorption and the dissolution kinetics of organic contaminants, both of which are limited by the slow speed of molecular diffusion. Also compiles methods for calculating the diffusion coefficients of organic compounds in aqueous solution or vapor phase through natural porous media.
