Definition: The movement of water, under hydrostatic pressure, through the interstices of a rock or soil, except the movement through large openings such as caves.  NOAAHydrology 

Flow of a liquid through an unsaturated porous medium such as snow under the action of gravity.  IACSSnow 

In hydrologic terms, the movement of water, under hydrostatic pressure, through the interstices of a rock or soil, except the movement through large openings such as caves.  NOAA-NWS 

The movement of a liquid such as water through the void spaces of a permeable solid such as snow or firn, the rate of movement being governed by the porosity and liquid content of the solid, the geometric attributes of the pores, including their diameter and tortuosity, and the response of the pore walls to wetting. See infiltration.  IHPGlacierMassBalance 

Downward motion of water through the soil or a snow layer.  WMOMeteoterm
