Percolation 同 Infiltration 有d咩分別？

percolation係滲透,infiltration係下滲,
地表水分會先進行infiltration才到percolation,
換言之infiltration係上層進行,percolation係下層進行,
所以infiltration既水量必定多於percolation~

given by the same piece of land, Infiltration occurs first , then followed by percolation.
Both are sub-surface runoff.

Infiltration is the process which water penetrates into the soil from the ground surface.

Percolation is the process that water penetrates into the permable rock layer from the soil.


hope this can help you :]
