Coefficient of Permeability

The coefficient of permeability measures how easily water can flow through a material, such as soil or rock. It depends on the material's properties—porosity and internal structure—and can vary widely. A high coefficient means water moves through quickly (like sand), while a low coefficient indicates slow movement (like clay). This value is important in fields like civil engineering and hydrogeology for designing foundations, managing groundwater, and controlling drainage systems. Essentially, it helps us understand and predict how water interacts with different materials in the environment.
