Infiltration | 1 – The flow or movement of water through the surface into the soil body or ground (illustrated). 2 – The absorption of liquid water by the soil, either when it falls as rain, or when applied as irrigation, or from a stream flowing over the ground. 3 – Flow from a porous medium into a channel, pipe, drain, reservoir or conduit. 4 – The infi..... | | Similar Terms |

Infiltration rate | 1 – The rate at which water penetrates the surface of a soil. The term is usually used to refer to water occurring as precipitation, but is also applied to water flowing or standing upon soil. 2 – The rate at which groundwater enters an infiltration ditch, gallery, drain, sewer or other underground conduit...... | | Similar Terms |
