This calculator helps estimate the infiltration rate of water into a soil. Infiltration is the process by which water on the ground surface enters the soil. It's a crucial factor in hydrology, agriculture, and environmental science, influencing groundwater recharge, runoff, and soil moisture levels. The rate of infiltration can be affected by soil type, soil structure, existing soil moisture, vegetation cover, and land use.
