Eutrophication Models for Lakes

Jørgen F. Simonsen, K. I. Dahl-Madsen

Open publisher page 7 citations

Abstract

In the years 1970-1977 eutrophication models have been developed and applied for about 15 shallow Danish lakes. The structure of these models are discussed. An example of the calibration of the model on data from Lake Gyrstinge in the Suså catchment area is shown, and the use of the model for calculating ecological consequences of changed hydraulic retention times is demonstrated. The dynamic eutrophication model is compared to the Dillon-Rigler version of the input-output model. Limitations of both types of models are discussed.
