Geiser (scientific computing, U. of Heidelberg, Germany and Humboldt U.) has published these research results on simulation models for severely contaminated groundwater due to radioactive fuels and chemical wastes, especially in regards to weakly coupled systems of equations of convection, diffusion and dispersion reactions. Aimed at researchers and scientists with a strong background in mathematics, this monograph describes the physics of the model before exploring the discretization, operator-splitting methods and analytical solutions of the research. Appendices include mathematical explorations of the Laplace Transformation as well as ordinary differential equations used in these models.
