We obtain the travelling wave solutions of nonlinear Richard's equation, expressing water content (moisture content) in unsaturated porous media. In the present analysis, the typical forms of hydraulic conductivity and diffusivity functions proposed by Witelski are considered. In particular, the travelling wave solutions for Richard's equation with nonlinear diffusivity and hydraulic conductivity are presented. The governing nonlinear partial differential equation is solved by modified F-expansion method with the help of symbolic computation system Mathcmatica. Soliton-like solutions are obtained and its physical interpretation is considered for the specific initial value problem. The obtained solutions reveal that the method is a very effective and powerful tool for solving various nonlinear partial differential equations arising in mathematical physics. (C) 2015 The Authors.
