Grain Size Distribution

Grain size distribution describes the range and proportion of different-sized particles within a material like soil or sediment. It shows how much of the material consists of fine particles, like clay or silt, versus larger ones, like sand or gravel. This distribution affects the material's properties, including drainage, stability, and strength. Understanding the grain size distribution helps in assessing soil behavior for construction, agriculture, and environmental management, by revealing how the particles are sorted and mixed across different sizes.
