Abstract
This paper describes a mathematical simulation model of the transformation of organic matter and biogenic compounds. The model is validated with observations made on Lake Ladoga. Despite the approximate nature of the biogenic load data, a good agreement is obtained between the calculated substance concentrations and available observations made during individual seasons for different areas of the lake. The model was developed by the author Leonov and this paper presents new model results with accurate formulations for nitrogen and carbon components. Comparison with observational data base collected during 1976–1979 shows that the model results provide good simulation of the annual seasonal changes in material concentrations in the identified regions of the lake.
