Throughout the world, we are daily discharging both treated and untreated wastewaters into various ecological systems such as rivers, lakes, estuaries, and oceans. As a result of physical, chemical, and biological phenomena, these inputs result in various levels of water quality at different locations and times in the aquatic ecosystem. A comparison between the actual and desired quality, the latter being functional of the water use(s), dictates the degree of environmental control, if any, of the discharge. An important aspect of water pollution abatement, therefore, is to be able to predict, through the use of mathematical models, the effects of wastewater discharge to a specific body of water. This allows for an appropriate decision-making process for water quality management.
This book, an updated version of the 1985 edition, contains thirteen chapters, beginning with a preface which provides the objective of the book. The primary objective is to offer a comprehensive survey of the biological, hydrological, mathematical, and biochemical aspects of stream, lake, estuary, and ocean pollution analysis. The book also contains ten appendices of useful tables and nomographs of pertinent data.
Chapters 1,2, and 3 provide the basic concepts of the biological, hydrological, and biochemical aspect of stream analysis,
