TENSION INFILTROMETER  

DÉFINITION

  • Tension infiltrometers have been widely used for in situ determination of the field-saturated hydraulic conductivity (Kfs) of soils under near-saturated conditions in the vadose zone (Meiers, 2002). Near-saturated conditions refer to measurements made over the negative pressure range, -20cm to 0.0cm, where water contents are nearly as high as those for saturation (Reynolds and Elrick, 1991). Tension infiltrometers determine the steady-state infiltration rate into the soil through a porous plate on which a constant negative water pressure (tension) is applied.
