چکیده مقاله:

The relation between volumetric water content and water potential for a soil is termed its Soil-Water Characteristics Curve (SWCC). This basic hydraulic property is closely related to the soil pore size distribution. In this study, basic soil parameters are used to develop a multifractal model of soil structure. After arriving at the most suitable fractal medium which is a multifractal one, the corresponding pore characteristics are implemented in a percolation network to calculate SWCC. Finally, a comparison is made between results obtained from the proposed model and the real soil behavior.
