ABSTRACT
This paper provides an overview of the usage of mathematical models in hydrology. A partial differential equation is solved with the help of Homotopy Perturbation Method (HAM). The equation is taken from flow of fluid in a reservoir. Results obtained shows that HAM is an effective method for these types of equations and provides a convergent solution.
