Eutrophication of Shallow Lakes: Modeling and Management [antikvár]

INTRODUCTION Man-made eutrophication has been considered as one of the most serious global water quality problems of lakes during the past 10-20 years- Increasing discharges of domestic and industrial waste water, the intensive use of crop fertilizers and the rise in airborne pollution can be mentioned among the major causes of this undesirable phenomenon- The typical symptoms of eutrophication are among others sudden algal blooms, water coloration, floating water-plants and debris, excreation of toxic substances causing taste and odor problems in the production of drinking water, and fish kills. These symptoms can easily result in limitations of water use for domestic, agricultural, industrial or recreational purposes. Consequently, eutrophication may lead to a devaluation of the lake-shore region, therefore the solution of this environmental problem is of direct economic concern. In 1977 and 1978 three state-of-the-art workshops were held at IIASA (Beck 1978, J^rgensen and Harleman 1978, and J0rgensen 1979)^ which overviewed the water quality problems Beck, M.B.
