Preface
The past 35 years have seen the emergence of a growing desire worldwide that positive
actions be taken to restore and protect the environment from the degrading effects of all forms
of pollution—air, water, soil, thermal, radioactive, and noise. Since pollution is a direct or
indirect consequence of waste, the seemingly idealistic demand for “zero discharge” can be
construed as an unrealistic demand for zero waste. However, as long as waste continues to
exist, we can only attempt to abate the subsequent pollution by converting it to a less noxious
form. Three major questions usually arise when a particular type of pollution has been
identified: (1) How serious are the environmental pollution and water resources crisis?
(2) Is the technology to abate them available? and (3) Do the costs of abatement justify the
degree of abatement achieved for environmental protection and water conservation? This
book is one of the volumes of the Handbook of Environmental Engineering series. The
principal intention of this series is to Giúp readers formulate answers to the above three
questions.
The traditional approach of applying tried-and-true solutions to specific environmental and
water resources problems has been a major contributing factor to the success of environmental
engineering, and has accounted in large measure for the establishment of a “methodology of
pollution control.” However, the realization of the ever-increasing complexity and interre-
lated nature of current environmental problems renders it imperative that intelligent planning
of pollution abatement systems be undertaken. Prerequisite to such planning is an under-
standing of the performance, potential, and limitations of the various methods of environ-
mental protection available for environmental scientists and engineers. In this series of
handbooks, we will review at a tutorial level a broad spectrum of engineering systems
(processes, operations, and methods) currently being utilized, or of potential utility, for
pollution abatement. We believe that the unified interdisciplinary approach presented in
these handbooks is a logical step in the evolution of environmental engineering.
Treatment of the various engineering systems presented will show how an engineering
formulation of the subject flows naturally from the fundamental principles and theories of
chemistry, microbiology, physics, and mathematics. This emphasis on fundamental science
recognizes that engineering practice has in recent years become more firmly based on
scientific principles rather than on its earlier dependency on empirical accumulation of
facts. It is not intended, though, to neglect empiricism where such data lead quickly to the
most economic design; certain engineering systems are not readily amenable to fundamental
scientific analysis, and in these instances we have resorted to less science in favor of more art
and empiricism.
Since an environmental engineer must understand science within the context of applications,
we first present the development of the scientific basis of a particular subject, followed by
exposition of the pertinent design concepts and operations, and detailed explanations of their
applications to environmental conservation or protection. Throughout the series, methods of
system analysis, practical design, and calculation are illustrated by numerical examples.These examples clearly demonstrate how organized, analytical reasoning leads to the most
direct and clear solutions. Wherever possible, pertinent cost data have been provided.
Our treatment of environmental engineering is offered in the belief that the trained engineer
should more firmly understand fundamental principles, be more aware of the similarities
and/or differences among many of the engineering systems, and exhibit greater flexibility
and originality in the definition and innovative solution of environmental system problems.
In short, an environmental engineer should by conviction and practice be more readily
adaptable to change and progress.
Coverage of the unusually broad field of environmental engineering has demanded an
expertise that could be provided only through multiple authorships. Each author (or group of
authors) was permitted to employ, within reasonable limits, the customary personal style in
organizing and presenting a particular subject area; consequently, it has been difficult to treat
all subject materials in a homogeneous manner. Moreover, owing to limitations of space,
some of the authors’ favored topics could not be treated in great detail, and many less
important topics had to be merely mentioned or commented on briefly. All authors have
provided an excellent list of references at the end of each chapter for the benefit of the
interested readers. As each chapter is meant to be self-contained, some mild repetition among
the various texts was unavoidable. In each case, all omissions or repetitions are the respon-
sibility of the editors and not the individual authors. With the current trend toward metrica-
tion, the question of using a consistent system of units has been a problem.Wherever possible,
the authors have used the British system (fps) along with the metric equivalent (mks, cgs, or
SIU) or vice versa. The editors sincerely hope that this redundancy of units’ usage will prove
to be useful rather than being disruptive to the readers.
The goals of the Handbook of Environmental Engineering series are: (1) to cover entire
environmental fields, including air and noise pollution control, solid waste processing and
resource recovery, physicochemical treatment processes, biological treatment processes,
biotechnology, biosolids management, flotation technology, membrane technology, desalina-
tion technology, water resources, natural control processes, radioactive waste disposal,
hazardous waste management, and thermal pollution control; and (2) to employ a multimedia
approach to environmental conservation and protection since air, water, soil, and energy are
all interrelated.
This book is Vol. 15 of the Handbook of Environmental Engineering series, which has been
designed to serve as a water resources engineering reference book as well as a supplemental
textbook. We hope and expect it will prove of equal high value to advanced undergraduate
and graduate students, to designers of water resources systems, and to scientists and
researchers. The editors welcome comments from readers in all of these categories. It is our
hope that the book will not only provide information on water resources engineering, but will
also serve as a basis for advanced study or specialized investigation of the theory and analysis
of various water resources systems.
This book, Modern Water Resources Engineering, covers topics on principles and appli-
cations of hydrology, open channel hydraulics, river ecology, river restoration, sedimentation
and sustainable use of reservoirs, sediment transport, river morphology, hydraulic
vi Prefaceengineering, GIS, remote sensing, decision-making process under uncertainty, upland erosion
modeling, machine learning method, climate change and its impact on water resources, land
application, crop management, watershed protection, wetland for waste disposal, water
conservation, living machines, bioremediation, wastewater treatment, aquaculture system
management, environmental protection models, and glossary for water resources engineers.
The editors are pleased to acknowledge the encouragement and support received from their
colleagues and the publisher during the conceptual stages of this endeavor. We wish to thank
the contributing authors for their time and effort, and for having patiently borne our reviews
and numerous queries and comments.We are very grateful to our respective families for their
patience and understanding during some rather trying times.
