Water Quality Management covers the fundamentals of water quality; water quality modeling and systems analysis of streams, reservoirs, and estuaries; and practical water quality topics and problems. The book presents topics on the legal aspects; the physical, chemical, and biological dimensions of water quality; and water quality requirements. The text also describes the pollution inputs from both point and nonpoint sources; eutrophication; thermal pollution; and groundwater quality. Detailed discussions on water quality parameters and characteristics; hydrologic and hydraulic aspects of water quality; mixing; and simple and complex water quality models are also included. The book further tackles topics on waste assimilative capacity determination, as well as effluent outfall design. Practicing environmental engineers and professionals involved in pollution abatement programs, environmental students undertaking studies in water quality management, and professionals involved in water quality management or water resources problems will find the text quite.
