Abstract

Pollution has become a very serious threat to our environment. Monitoring pollution is the rst step
toward planning to save the environment. The use of di
erential equations, monitoring pollution has
become possible. In this paper, a Ritz-collocation method is introduced to solve non-linear oscillatory
systems such as modelling the pollution of a system of lakes. The method is based upon Bernoulli
polynomials. These polynomials are rst presented. The Bernoulli Ritz-collocation method is then
utilized to reduce modelling the pollution of a system of lakes to the solution of algebraic equations. An
illustrative example is included to demonstrate the validity and applicability of the proposed method.
