  • In the present analysis, the modified homotopy analysis method has been employed to find an approximate analytical solution of Richards’ equation. This method is the slight modification of standard homotopy analysis method. Some standard cases of Richards’ equation have been discussed as an example to illustrate the high accuracy and reliability of modified homotopy analysis method. The result obtained from the proposed method is very close to the exact solution of the problem. It is concluded that modified homotopy analysis method is the better alternative to some standard existing methods to solve some realistic problems arising in science and technology.
