Abstract

In the paper by Mitreski et al.' a dynamic biogeochemical model has been proposed, which tends to describe some of the processes that contribute to the eutrophication of Lake Ohrid. By balancing the complexity between the scope of the model and the available data, we selected state variables and formulated mathematical expressions. With three differential equations, we took into account the change of available phosphorus, as well as time dependent behaviour of phytoplankton and zooplankton concentrations in the lake. By considering both model output and lake-wide observations, the suitability of the model was analysed. The main goal of this paper is to give experimental validation of the
