The X-ray computed tomography and multifractal analysis are underused promising techniques to obtain soil structure quantitative parameters. By 3D imaging, computed tomography allows the study of soil structure and other attributes, such as, for example, the soil surface state, without physical interference in the sample. Thus, this technique allows characterize and relate attributes that influences the soil behavior and erosion mechanics. The analysis of this structure can be assisted by quantitative index calculation and fractal techniques have been used on soil science as an alternative to conventional geometry. Some multifractal spectrum parameters (symmetry and bending; capacity, entropy and correlation dimensions) are related to porous system heterogeneity, however, the relationship between a particular multifractal response and the soil behavior is not yet established. The objective of this study is to explore the use of computed tomography and multifractal analysis to study highly structured soils superficial crusting and obtain soil structural quantitative parameters.
