Granulometry is the study and measurement of the size distribution of particles in a material. It is commonly used in fields like geology, soil science, and materials engineering to analyze the composition of sediments, soils, and other granular materials. By understanding particle sizes, scientists can infer properties such as permeability, stability, and how materials will behave in different environments. The process of granulometry often involves techniques like sieving, laser diffraction, or sedimentation analysis. These methods help categorize particles into different size ranges, which can be crucial for applications in construction, agriculture, and environmental science. Accurate granulometric data aids in making informed decisions regarding material use and management.
