Infiltration - GCSE Geography Definition

Infiltration is the process where water on the ground's surface soaks into the soil. It is an important part of the water cycle and affects how much water is available in the soil for plants and trees to grow. The rate of infiltration can be influenced by several factors, such as soil type, vegetation cover, and land use. For example, sandy soils allow water to infiltrate quickly, whereas clay soils absorb water more slowly. Infiltration helps prevent flooding by reducing surface runoff, and it also refills underground water stores called aquifers. Understanding infiltration is essential for managing water resources and preventing soil erosion.
