Suffusion prediction model based on physical parameters for gap-graded and well-graded soils

Suffusion is one of the four types of internal erosion and accounts for 46% of erosion phenomena in earth dams. Suffusion is an erosion of fine particles inside the soil structure that move out of the voids between coarse particles caused by permeability flow. Identification of internal erosion is necessary to mitigate the loss of humans and property as underground erosion occurs.
