The article compares different models for eutrophication and analyzes their key parameters. Single nutrient load models focus on lake depth, retention time, settling velocity, and exchange coefficient. Phytoplankton-related models consider nutrient concentrations, growth rates, and half-saturation constants. Ecological dynamics models look at water quality, physics, biology, and water dynamics. The first two models are best for shallow, stable water bodies, while ecological dynamics models are suited for complex pollution and spatial variation. These findings can help choose the right model and parameters for studying eutrophication.
