This comprehensive work integrates knowledge from physics, chemistry, biology, mathematics, geology, engineering, and several other fields. Its purpose is to provide solution methods, techniques of parameter estimation, and tools for solving the complex problems of mathematical modeling. The main topics presented include fundamentals of mathematical modeling of migration processes; analytical, numerical, and inverse solutions to migration problems; and techniques of parameter estimation and monitoring of migration processes. The book is perfect for anyone involved in the areas of hydrogeology, soil science, environmental engineering, subsurface cleanup, water sciences, agronomy, land development, and civil engineering. It provides professionals with a survey of the methodology of migration model building, the mathematical tools for solving these models, and the technique of parameter estimation in laboratories and in the field. Consultants will appreciate the book's multidisciplinary theoretical background and first approximations for a broad variety of migration data. Professors and students gain an integrated survey of subsurface solute and heat transport, storage, transformation, and exchange processes in both theoretical and practical applications, complete with example problems and solutions.
