Eutrophicationent area the inflow of nutrient to the lake is consistently higher than the outflow. The phenomenon of eutrophication becomes apparent principally by the development of large blooms of algae as the increased potential productivity of the lake responds to sunlight.

n the UK and the USA is included as is an informative introduction to the potentially confusing subject of water quality modelling. The book provides the student, researcher and scientist interested in river pollution and pollution control with the most up-to-date and comprehensive coverage of the subject available anywhere.

er pollution. The chemical, physical and biochemical parameters of water quality, without an appreciation of which no true understanding of river pollution control is possible, are discussed in some detail as are the roles of the variety of micro and other organisms present in natural waters. Self-p
