Water content, abbreviated as w, also called moisture content, a dimensionless number, is the ratio of weight of soil to the weight of water or the quantity of water contained in a material.
The measurement of water content can be performed using various techniques, including gravimetric methods, where the weight of the water is determined, and volumetric methods, where the volume of water is measured. Water content is essential for understanding the behavior of materials in terms of strength, compaction, permeability, and deformation. In agriculture, it helps determine irrigation requirements and assess soil fertility. In environmental sciences, water content is crucial for studying water availability, soil-water interactions, and hydrological processes.
