PPT-Infiltration

Infiltration definitions Infiltration rate the volume of water flowing into the soil profile per unit of surface area per unit time Infiltrability the infiltration rate resulting when water at atmospheric pressure is made freely available at the soil surface.

Steady Horizontal Flow. Soil Water Processes. P = Q + ET + G . + . Δ. S. Infiltration. Infiltration capacity: . The maximum rate at which water can enter soil. . Infiltration capacity curve:. A graph showing the time-variation of infiltration capacity if the supply were continually in excess of infiltration capacity. . Overview Infiltration: The movement of water from the soil surface into the soil Redistribution:The subsequent movement of infiltrated water in the unsaturated zone of a soil. This can involve exfilt past . present and future . Chris Searle. Grower Liaison Officer . Suncoast Gold Macadamias . Gympie . Qld. Background.
