  • It is intended that this book be suitable for a variety of engineers and ecologists, who may wish to gain an introduction to the rapidly growing field of ecological and environmental modelling. An understanding of the fundamentals of environmental problems and ecology, as presented for instance in the textbook Principles of Environmental Science and Technology is assumed. Furthermore, it is assumed that the reader has either a fundamental knowledge of differential equations and matrix calculations or has read the Appendix, which gives a brief introduction to these topics....

  • The environment is key to sustaining human economic activity and well-being, for without a healthy environment, human quality of life is reduced. Most people would agree that there are also many reasons to protect the environment for its own inherent worth, and especially to leave a legacy of fully functioning natural resources. Sustainable land management refers to the activities of humans and implies that activity will continue in perpetuity. It is a term that attempts to balance the often conflicting ideals of economic growth and maintaining environmental quality and viability....

  • McKay, Donald. "Advection and Reactions" Multimedia Environmental Models Edited by Donald McKay Boca Raton: CRC Press LLC,2001 CHAPTER 6 Advection and Reactions 6.1 INTRODUCTION In Level I calculations, it is assumed that the chemical is conserved; i.e., it is neither destroyed by reactions nor conveyed out of the evaluative environment by flows in phases such as air and water. These assumptions can be quite misleading when determining of the impact of a given discharge or emission of chemical.

  • Environmental Engineer’s Mathematics Handbook brings together and integrates in a single text the more practical math operations of environmental engineering for air, water, wastewater, biosolids and stormwater. Taking an unusual approach to the overall concept of environmental engineering math concepts, this offers the reader an approach that emphasizes the relationship between the principles in natural processes and those employed in engineered processes.

  • The purpose of this text is to provide the basis for an upper-level undergraduate or graduate course over one or two semesters, covering basic concepts and examples of fluid mechanics with particular applications in the natural environment. The book is designed to meet a dual purpose, providing an advanced fundamental background in the fluid mechanics of environmental systems and also applying fluid mechanics principles to a variety of environmental issues.

  • This book is intended to introduce environmental scientists and managers to the statistical methods that will be useful for them in their work. A secondary aim was to produce a text suitable for a course in statistics for graduate students in the environmental science area. I wrote the book because it seemed to me that these groups should really learn about statistical methods in a special way. It is true that their needs are similar in many respects to those working in other areas.

  • As a wetland of international importance located in China, the Poyang Lake Basin's incredible topographical and biological diversity has provided a congregating point for scientists from around the world to engage in cross-disciplinary research. In particular, the International Conference on Poyang Lake Complex Environment System was instrumental in bringing together scholars from China, North America, and Europe to explore the latest innovations in water resource science and watershed management.

  • Ecotoxicological models have been applied increasingly to perform chemical risk assessments since the first models of this kind emerged about 25 years ago. The first ecotoxicological models were applied to very specific cases — for instance, cadmium contamination of Lake Erie or mercury contamination of Mex Bay, Alexandria. The models were inspired by the experience gained in ecological modeling and therefore contained good descriptions of ecological processes. Slightly later, the so-called fate models emerged, which were first developed by McKay and others.

  • The use of models to provide additional details on contaminant fate and transport has rapidly increased in the past 3 decades. The increasing global recognition of the potential risks associated with surface water or ground water contamination and speciÞc environmental regulations implemented after 1980 have demanded a more accurate understanding of these risks as they relate to human health and the environment.

  • Since the Second World War, and especially since the publication of Rachel Carson’s Silent Spring in 1962, there has been growing concern about contamination of the environment by “man-made” chemicals. These chemicals may be present in industrial and municipal effluents, in consumer or commercial products, in mine tailings, in petroleum products, and in gaseous emissions. Some chemicals such as pesticides may be specifically designed to kill biota present in natural or agricultural ecosystems. They may be organic, inorganic, metallic, or radioactive in nature.

  • Statistical models are empirical. Although they are derived from observations, the relationship described must have a basis in our underlying understanding of processes if we are to have faith in the predictive capabilities of the model (National Research Council 2000).

  • In terms of teaching and learning, there are many approaches, which have been applied in the past. However, more recently, one approach has come to the forefront as a model for success. In this chapter, we will discuss the learner-centered approach, a model of learning and teaching that gives the student the choice and flexibility to learn in a way that optimizes his/her potential strengths and interests.

  • Non-market valuation has become a broadly accepted and widely practiced means of measuring the economic values of the environment and natural resources. In this book, the authors provide a guide to the statistical and econometric practices that economists employ in estimating non-market values. The authors develop the econometric models that underlie the basic methods: contingent valuation, travel cost models, random utility models and hedonic models.

  • This book consists of a collection of articles describing the emerging and integrated area of Energy,Natural Resources and Environmental Economics. A majority of the authors are researchers doing applied work in economics, finance, and managemen science and are based in the Nordic countries. These countries have a long tradition of managing natural resources. Many of the applications are therefore founded on such examples.
