Development of mathematical models of lakes began as a result of the resurgence of ecology and the need for action to halt the marked deterioration of ecosystems. Although computers are now able to solve systems of differential equations once considered impracticable, the study of complete systems with biological components is still an arduous task. In such cases the skill of the modeller is in grasping the essential characteristics of the experiment and in drawing the right conclusions when comparing model values with empirical results. This monograph is the result of long collaboration between the modellers and experimenters in addressing the problems of lake ecology. The basic concepts of lake modelling are outlined: for eutrophication in Part 1, and for pollution by heavy metals in Part 2. Various instances of lake pollution are then discussed in Part 3, which presents applications of the different models to specific problems in three subalpine lakes: characterisation of the phosphorus cycle in the Lago di Lugano, the interaction between lake and sediments in the Lago di Varese and the evolution of copper concentration in the Lago d'Orta.
