Abstract

The granulometric classification of soils is crucial in various scientific disciplines, including geotechnics, agronomy, geology, hydrogeology, and atmospheric studies. This mini review compares 15 of the most widely used granulometric classification methodologies for soils, sediments, and wastes over the last seventy years. The study utilizes 244 mine tailings samples from 27 tailings storage facilities (TSFs) to demonstrate classification techniques used in geotechnical, agronomic, geological, and hydrogeological contexts. Findings reveal significant variability in particle size distributions, influencing soil behavior, hydrodynamic regimes, water retention, and pollutant transport. This variability arises because each discipline’s classification considers different parameters as crucial for its specific needs.
