We investigate effect of variable properties on natural convective heat transfer flow over a vertical wavy surface embedded in a fluid saturated porous medium with thermal radiation and heat sources. The Darcy model is used to study the fluid flow in the saturated porous medium. Moreover the temperature dependent variables properties are considered. The vertical wavy wall and the governing equations for flow heat ad mass transfer are transformed to a plane geometry case by employing the Rungre-Kutta fourth order with Shooting technique. The non-dimensional velocity temperature graphs as well as rate of heat transfer coefficients are displayed graphically for different values of variable parameter variable thermal conductivity parameter radiation parameter and amplitude of the wavy surface.
