Providing a comprehensive analysis of the dynamics complexities of environmental systems - both natural and manmade - Process Dynamics in Environmental Systems is a unique, practical introduction to the issues and design mandates central to environmental engineering. Beginning with a broad overview of the factors and features of environmental systems and processes, the book then clearly details the general nature of fundamental processes, the character of the different types of systems in which they occur, and the way in which these factors influence process dynamics and environmental systems. The book then examines the core elements of process analysis - energetics, reaction rates, and reactor dynamics - and shows how process modeling integrates these elements in quantitative descriptions and in designs of engineered systems. Central to the structure of this book is a detailed analysis of the nature of reaction and transport phenomena - the two fundamental aspects of any environmental system. Including a look at reactions on both a macroscopic and microscopic scale, the book examines the mechanics of macroscopic and microscopic transport processes, outlining mass transport concepts basic to an understanding of reaction phenomena and reactor engineering. A synthesis of the various aspects of process dynamics forms the book's conclusion, enabling the reader to skillfully apply the concepts of process dynamics to the interpretation and design of environmental systems. An ideal reference/handbook to the theory and uses of process dynamics, the book's practical, instructive format includes detailed example problems, assigned problems with answers, as well as suggested supplementary reading. Useful general appendices are provided, and many individual chapters also feature appendices which address issues specific to the chapter.
