If infiltration rate were calculated every 200 seconds, you can see that infiltration slows down as the ground saturates (see figure below). percolation testing, the rate used in design should be compared to the anticipated range of infiltration rates based on the Hydrologic Soil Group and the Unified Soil Classification of soils at the site. 82 23 0000009718 00000 n 0000000016 00000 n %%EOF Infiltration and percolation are two related but different processes describing the movement of moisture through soil. Natural refilling of deep aquifers is a slow process because groundwater moves slowly through the unsaturated zone and the aquifer. Infiltration is defined as the downward entry of water into the soil or rock surface (SSSA, 1975) and percolation is the flow of water through soil and porous or fractured rock.

The substance which has entered the pores or cavities of a body. Although percolation is the movement of water through soil, infiltration is the movement of water into soil. 0000003367 00000 n Infiltration Rate: The rate at which water infiltrates into the ground at any given moment, regardless of the current soil saturation.
