The suffusion tests were performed by applying a downward seepage flow under multi-staged hydraulic gradient. Experiments were carried out at the scale of a soil sample. Soil samples with structural homogeneity and soil samples with structural heterogeneities were tested. Homogeneous soil samples were used for comparison. Two heterogeneity configurations based on fines content (15% and 25%) and density index (I D = 0.1 and I D = 0.4) were tested. measurements of flow velocity, total eroded mass and erosion rate were carried out. The analysis of results obtained has shown that soils with induced structural heterogeneities are more erodible than soils with homogeneous structure, independently of the fines content and the density index. The specimens with low density index (I D = 0.1) are more erodible than those with medium density index (I D = 0.4). Full Text Additional Declarations No competing interests reported.
