Modeling the pollution of a system of lakes

Pollution has become a very serious threat to our environment. Monitoring pollution is the first step toward planning to save the environment. The use of differential equations, monitoring pollution has become possible. In this paper, compartment modeling is introduced to model the pollution of a system of lakes by a system of differential equations. A system of three lakes, interconnected by channels flowing between them is introduced. Input pollution models are mathematically analyzed and three different types of input models for monitoring the pollution in a lake are introduced.
