ABSTRACT
This chapter presents institutionalized and mediated models, which are particularly strong management tools. There are hundreds of ecological–environmental models of aquatic ecosystems available in the literature. Standard models are available to solve the most basic aquatic ecosystem problems, for instance, eutrophication, water level problems, acidification, and oxygen depletion. The chapter demonstrates to managers of aquatic ecosystems, limnologists, chemists, sanitary engineers, and other interested parties of the possibilities that mathematical modeling offers as a tool to support management decisions. A good environmental model can be a powerful tool in the decision-making process for management actions. An intensive measuring period, with several sets of measurements each week during the spring and summer bloom period, can first of all be applied to improve parameter estimation, which is often a focal problem in developing ecological models. The prognosis gives a pronounced effect of 98% phosphorus removal, which could therefore be recommended to the appropriate environmental authorities.
