Abstract
This paper analyses the mathematical model of the evolution of phosphorus in a bilayer lake based on the kinetic equations which describe this process. The mathematical modelling was developed using Scilab-Xcos and allows an over time visualization of the water levels evolution with the following parameters: soluble phosphorus (Ps) insoluble phosphorus (Pi) and total phosphorus (Pt) for the two layers of the lake, namely the epilimnion and the hypolimnion. Furthermore, this work presents a simulation of the above mentioned parameters.
