Amazon.com description: Product Description: This international, interdisciplinary account presents a unified account of ecotechnology--the practice of ecologically sound approaches to engineering. The first section of the book introduces the basic concepts and principles of ecotechnology. The second section of the book comprises case studies of ecological engineering from around the world, including cases from Denmark, China, Japan, the United States, and Canada. Most of the examples are applications of aquatic ecosystems, such as hydrological modification, pollution control, wetland management, and lake, reservoir, and stream restoration. Chapters in the second section follow a common format--a survey of the problem or existing methodologies, a discussion of where and when these methods are ecologically sound, and a case study to illustrate in detail the proper use of the ecological engineering practice.
