Rainfall Infiltration

Rainfall infiltration refers to the process where raindrops penetrate the soil surface and move downward into the ground. This process helps replenish underground water supplies and supports plant growth. The rate of infiltration depends on factors such as soil type, moisture content, land slope, and the intensity of rainfall. For example, sandy soils allow water to quickly seep in, while clay soils slow it down. Proper infiltration reduces surface runoff, which can cause erosion and water pollution. Understanding infiltration is essential for managing water resources, agriculture, and urban planning to ensure sustainable water use and minimize flooding risks.
