Any numerical subsurface model is comprised of three components: a
theoretical basis to translate our understanding phenomena into
partial differential equations and boundary conditions, a numerical
method to approximate these governing equations and implement the
boundary conditions, and a computer implementation to generate a
generic code for research as well as for practical applications.
Computational Subsurface Hydrology: Reactions, Transport, and Fate
is organized around these themes. The fundamental processes
occurring in subsurface media are rigorously integrated into
governing equations using the Reynolds transport theorem and
interactions of these processes with the surrounding media are
sophisticatedly cast into various types of boundary conditions
using physical reasoning. A variety of numerical methods to deal
with reactive chemical transport are covered in Computational
Subsurface Hydrology: Reactions, Transport, and Fate with a
particular emphasis on the adaptive local grid refinement and peak
capture using the Lagrangian-Eulerian approach. The topics on
coupled fluid flows and reactive chemical transport are unique
contributions of this book. They serve as a reference for research
as well as for practical applications with a computer code that can
be purchased from the author. Four computer codes to simulate
vertically integrated horizontal solute transport (LEMA),
contaminant transport in moving phreatic aquifers in three
dimensions (3DLEMA), solute transport in variably saturated flows
in two dimensions (LEWASTE), and solute transport under variably
saturated flows in three dimensions (3DLEWASTE) are covered. These
four computer codes are designed for generic applications to both
research and practical problems. They could be used to simulate
most of the practical, real-world field problems. Reactive chemical
transport and its coupling with fluid flows are unique features in
this book. Theories, numerical implementations, and example
problems of coupled reactive transport and flows in variably
saturated media are presented. A generic computer code,
HYDROGEOCHEM 3.0, is developed. A total of eight example problems
are used to illustrate the application of the computational model.
These problems are intended to serve as examples for setting up a
variety of simulations that one may encounter in research and
field-site applications. Computational Subsurface Hydrology:
Reactions, Transport, and Fate offers practicing engineers and
scientists a theoretical background, numerical methods, and
computer codes for modeling contaminant transport in subsurface
media. It also serves as a textbook for senior and graduate course
on reactive chemical transport in subsurface media in disciplines
such as civil and environmental engineering, agricultural
engineering, geosciences, soil sciences, and chemical engineering.
Computational Subsurface Hydrology: Reactions, Transport, and Fate
presents a systematic derivation of governing equations and
boundary conditions of subsurface contaminant transport as well as
reaction-based geochemical and biochemical processes. It discusses
a variety of numerical methods for moving sharp-front problems,
expounds detail procedures of constructing Lagrangian-Eulerian
finite element methods, and describes precise implementation of
computer codes as they are applied to subsurface contaminant
transport and biogeochemical reactions.
