Topics are developed through the use of computer exercises using practical problems as examples.

The past few years have seen the emergence of a growing, widespread desire in this country, and indeed everywhere, that positive actions be taken to restore the quality of our environment, and to protect it from the degrading effects of all forms of pollution-air, noise, solid waste, and water. Since pollution is a direct or indirect consequence of waste, if there is no waste, there can be no pollution, and the seemingly idealistic demand for "zero discharge" can be construed as a demand for zero waste. However, as long as there is waste, we can only attempt to abate the consequent pollution by converting it to a less noxious form. In those instances in which a particular type of pollution has been recognized, three major questions usually arise: (1) How serious is the pollution? (2) Is the technology to abate it available? and (3) Do the costs of abatement justify the degree of abatement achieved? The principal intention of this series of books on environmental engineering is to help the reader formu late useful answers to the second and third of these questions, i. e., to outline the best currently available engineering solutions, and to examine their costs in the light of the real level of benefits afforded."

This book presents an up-to-date overview of the characterization, risk assessment and remediation of mercury-contaminated sites. Many industrial activities, including the mining of gold, silver, and mercury itself, have caused mercury contamination of terrestrial and aquatic systems. Unlike other metals, which are generally not very volatile, mercury from contaminated sites can have a significant impact on remote ecosystems via the atmospheric pathway. Thus, mercury contamination is not only a local issue, but also has global dimensions.This book summarizes, for the first time, works from Europe, Russia and the American continent. Review chapters are supplemented by detailed, international case studies.

This monograph provides an overview of the principles required for a service orientation in the management of irrigation and drainage systems. The material covered is designed to emphasize an area largely neglected in the irrigation and drainage management literature. The dominating philosophy underlying this book is that irrigation and drainage systems must be managed as a service business responsive to the needs and changing requirements of its customers. It is postulated that this service approach to the management of irrigation and drainage systems consitutes a key element of the startegy that is needed to improve the current level of performance of many irrigation and drainage systems worldwide. Enhanced performance of irrigation is a prerequisite if we are to face the enormous challenge of producing greater quantities of food to meet the demand of a growing population. This is particularly the case in an environment with increasing competition for water from industry and urban water users, set against mounting concerns about environmental sustainability.

Man's control over the elements of land and water for the purposes of agriculture was fundamental to the development of civilisations in the past, and remains so today. This volume deals with the processes of irrigation, and land drainage and reclamation, and illustrates the variety of technological and engineering solutions in a wide chronological and geographical perspective. The sophistication of many pre-modern systems is clear, as is the impact of modern technologies. Important points that emerge are that there was no steady or linear progression in techniques across time - instances of the transfer of ideas are balanced by cases of independent development - and that the correlations between irrigation systems and social structures demand more complex explanations than often proposed.

Sediment transport, two-phase flow and loose boundary hydraulics are some of the problems of interaction between fluid flow (water or air) and boundaries that may be non-cohesive (alluvial) or cohesive. Unlike in classical hydraulics, these boundaries can change their shape and texture with changing flow conditions. Some of the material from the boundaries may be entrained into the flow, or sediment may be added to the flow, sometimes by tributaries as suspended matter. One instance is the transport of granular material in pipelines Since the changing boundaries are the central feature of most flow processes in nature, the term loose boundary hydraulics is here introduced.
Examines the physical processes involved in the interaction between air or liquid flow and the solid boundaries of its movement, showing how the properties of each material affect the dynamics between them.

High quality fresh water is limited in quantity and there is a need for comprehensive water management involving representatives of all those who use water. Effective management must ensure that the best use is made of available supplies, including protection from pollution, and to limit conflicts over access to fresh water. This calls for the establishment of clearly defined policies and strategies as well as for the development of enforceable mechanisms and tools for water pollution control.

Introducing a novel approach to setting environmental pollution standards that allow for proper treatment of uncertainty and variation, this book surveys the forms of standards and proposes a new kind of "statistically verifiable ideal standard." Setting Environmental Standards includes: a current analysis regarding the treatment of uncertainty and variation in environmental standard setting a review of basic principles in standard setting, including costs, actions and effects, and benefits examples where uncertainty and variation have been well-treated in current practice as well as examples where clear deficiencies are apparent specific proposals for the future approach to setting environmental pollution standards - encompassing the anticipated elements of uncertainty and variability The issues discussed serve statisticians as well as those persons involved with environmental standards. Scientists in agencies responsible for setting standards, in organizations advising such agencies or working in industries subject to these standards, will find Setting Environmental Standards an invaluable reference.

This volume examines energy dissipators mainly in connection with dam structures and provides a review of design methods. It includes topics such as hydraulic jump, stilling basins, ski jumps and plunge pools. It also introduces a general account of various methods of dissipation, as well as the governing flow mechanisms.

Geographic information system (GIS) computer technology is revolutionizing the way we interact with information. Data, text, drawings, maps, and images contain information that can be accessed and used intuitively through drawings containing graphical representations of the facilities to which they apply, e.g., emission stacks, sampling locations, and sites, to name only a few examples.
Environmental GIS technology is being applied with increasing frequency to manage industrial facilities. Environmental GIS describes the application of this information technology. It addresses environmental, safety, and health (ES&H) information management in an integrated manner. The book focuses on dealing with information from an organizational or corporate standpoint, meaning that the needs are not specialized to the ES&H area, but are an inherent part of managing the organization. Environmental, safety, and health information management needs are examined in the context of the overall corporate information flow. This book addresses

Stormwater infiltration is the most complete approach to stormwater management. Only infiltration can simultaneously solve problems of water quality, flood control, streambank erosion, aquifer recharge, and maintenance of downstream base flows and wetland hydroperiods. Stormwater Infiltration is the first book to explain the principles of natural science on which infiltration is based, how to apply infiltration to any region of the country, and what kinds of results can be expected. It brings into one publication the complete range of necessary information on soils, vegetation, infiltration, hydrology, design criteria, site layout, construction process for surface and subsurface basins, porous paving materials, feasibility, maintenance, and performance. It draws more than half a century's actual experiences from all over the United States to place stormwater management in a context of environmental balance and quality for human life.

Its subject matter is of interest to geographers, planners and coastal scientists alike.

The first meeting in this series was organized by Prof. Pawlowski and Dr. Lacy in 1976 at the Marie Curie-Sklodowska University in Lublin, Poland. The conference dealt with various physicochemical methodologies for water and wastewater treatment research projects that were jointly sponsored by US EP A and Poland. The great interest expressed by the participants led the organizers to expand the scope of the second conference, which was also held in Poland in September 1979. The third and enlarged symposium was again successfully held in 1981 in Lublin, Poland. At that time the participating scientists and engineers expressed their desire to broaden the coverage as well as the title of the conference series. The International Committee, ap proved the title "Chemistry for the Protection of the Environment" and designated that date of the fourth conference, CPE IV, which was convened in September 1983 at the Paul Sabatier University in Toulouse, France, and was hosted and arranged by Prof. A. Verdier. This conference series included participants from various government agencies, academia, and the private sector, representing industrialized countries as well as emerging nations, both the East and West in an independent, non politica forum."

This is a comprehensive work of reference for engineers dealing with the hydraulic problems that occur along coastlines and estuaries and in harbours. This branch of engineering has experienced rapid and profound changes since the 1960s due to the introduction of powerful computer modelling techniques. The book presents concise reviews of key topics on these techniques as well as the traditional civil engineering aspects of design and construction of coastal and maritime works. The powerful tools which are now available for computational and numerical modelling of hydraulic systems have to a considerable extent replaced physical models as the most appropriate means of investigating and selecting economic design options. This development has taken place alongside a greater understanding of the transport processes of granular and cohesive sediments, and an increasing concern with the environmental impact of engineering works. At the design stage, the engineer now commonly has to demonstrate the impact of the proposed works on the natural/watery environment. The chapters are presented under seven main headings: the physical environment; the scientific background; numerical tools and t
