The key difference between infiltration and percolation is that the infiltration refers to the filtration of rainwater from the surface of the ground while percolation refers to the filtration of infiltered water through soil particles and porous materials such as fractured rocks etc. Kirkham, in Principles of Soil and Plant Water Relations (Second Edition), 2014.

It is most often measured in meters per day but can also be measured in other units of distance over time if necessary. See more. As we mentioned before, the bulk of rainwater and melted snow end up infiltrated. The rate of this movement is called the infiltration rate.If rainfall intensity is greater than the infiltration rate, water will accumulate on the surface and runoff will begin. 15cm). . Infiltration. Infiltration is the process by which precipitation or water soaks into subsurface soils and moves into rocks through cracks and pore spaces. M.B. The other starts the stopwatch, and then record the water level every 30 seconds.
