Fractal Model to Interpret Porosity-Dependent Hydraulic Properties for Unsaturated Soils

Abstract

This paper presents a basic fractal model to evaluate the impacts of starting porosity on the dirt water maintenance bend and pressure-driven conductivity of unsaturated soils. In the proposed applied model, the difference in most extreme pore span, which generally decides the difference in the air-passage esteem, is straightforwardly connected with the fractal aspect of pore volume (D) and porosity change. The water-powered properties of unsaturated soils are then represented by the greatest pore sweep, the fractal aspect of pore volume (D), and the fractal aspect of drainable pore volume (Dd ≤ D). The new fractal model eliminates the experimental fitting boundaries that have no actual significance from existing models for porosity-subordinate water maintenance and pressure driven conduct and utilizes boundaries of fractal aspects that are characteristic for the idea of the fractal permeable materials. The proposed model is then approved against exploratory information from the writing on soil-water maintenance conduct and unsaturated conductivity.
