Nemerow, Nelson L.
A comprehensive description of the analysis of water pollution that presents a careful balance of the biological, hydrological, chemical and mathematical concepts involved in the evaluation of stream quality.Computation techniques for deoxygenation and reaeration rates are described and analyzed, as are all factors affecting oxygen concentration to give an overall oxygen sag curve in a stream. Topics included in this text are chemical water qualities for different stream uses, measurement of pollution index, stream management, and estuary analysis.
