| Abstract: | In this paper, describing soil structure and characterizing soil hydraulic properties with fractal theory are reviewed since 1980s. Based on the theory, the fractals of porous media are characterized by fractal dimensions of soil pores, particle-size distribution and particle surface or volume of soils, and the fractal models of soil water retention characteristics and hydraulic conductivity are determined accordingly. Also the advances of fractal theory in hydraulic properties are discussed. |

| Keywords: | soil water soil hydraulic properties self-similar fractal dimension |
