Engineering Management of Water Quality [antikvár]

PREFACEIn organizing and developing this book the author intended to present and interpret the subject of water quality management in such a manner as to stimulate thinking on the part of the reader. Although its use as lecture material originally motivated the writing, the author speaks to a wider audience than students in formal classes. The book is useful both in and out of the classroom, and it avoids the impersonal, formal approach without sacrificing rigor or completeness.When used as text material, the author believes that this work will help the sanitary engineer develop an understanding of the public policy framework, and the overall system in which engineered systems for upgrading the quality of water make sense and which may be expected to function harmoniously for quality objectives. It lays the groundwork for the more conventional technical courses in the principles, theory, and design of water supply and waste-water treatment plants. For the student of water resources engineering, it is intended to develop an understanding of the place of water quality control in water resources management, but anticipates that the student will follow it with courses in the economic and planning aspects of water resources development and in its philosophical, institutional, political, and legal aspects as well.For the practicing engineer and other readers, the work directs attention to recent changes in the rationale underlying public policy in the resources field, and to the broad systems concepts which modern engineering must apply to public works, with enough review of current technology and future possibilities to provide a basis for individual evaluation of man's social goals and his present technological ability to achieve them in relation to water resources.This work on the water quality management aspect of the subject of water resources development and management was originally prepared by the author as a text for one of four graduate courses comprising a
