WebFeb 5, 2024 · Infiltration is the process by which water on the ground surface seeps into the soil and the infiltration rate is the velocity at which water enters the soil. It continuously affects the magnitude and distribution of the overland flow and acts as an indicator of the soil’s ability to allow movement of water into and through the soil profile. Web4.3.1 Horton infiltration In general, for a given constant storm, infiltration rates tend to decrease with time. The initial infiltration rate is the rate prevailing at the beginning of the …
