Discussion of "Influence of particle-size distribution homogeneity on shearing of soils subjected to internal erosion".

The article presents a discussion of the research paper "Influence of Particle-Size Distribution Homogeneity on Shearing of Soils Subjected to Internal Erosion" by S. Li, A. R. Russell and D. Muir Wood published in the "Canadian Geotechnical Journal" in 2020. The discussion provided a few observations about the test procedure and preparation of soil samples used to study the internal erosion process of granular soils. It also addressed the threshold value of fines.
