Review on Fractal Models for Soil Water Retention Curve
The fractal approach appears to be a useful tool in understanding of soil as a porous medium and study of its hydraulic characteristics. Fractal models are mathematically developed and their parameters have physical meanings. In this study, different fractal models for soil water retention curve have been reviewed which have been presented in the literatures such as Tyler and Wheatcraft (1990), Rieu and Sposito (1991), Perrier et al. (1996), Perfect et al. (1996), Perfect (1999), Perrier et al. (1999), and Millán and González-Posada (2005). Pore-solid fractal approach introduced by Perrier et al. (1999) seems to be an appropriate model for simulating soil water retention curve. With this model, pore phase and matrix phase have a finite mass even for an infinite number of iterations, which indicate an important difference from traditional fractal pore models which assume two phases only.
