Abstract: Basic components of an aquatic ecosystem are modified continuously by such ecologic processes as photosynthesis, respiration, zooplankton grazing, fish predation, nutrient recycling, sedimentation and various transport phenomena. A set of differential equations describing these processes can be assembled and operated simultaneously to model physical, chemical and biological behavior of such an ecosystem. Preliminary experiments with an ecologic model of this type indicate the reasonableness of the technique. It is concluded that model development and application will greatly aid a more fundamental understanding of eutrophication processes and their control.
