= Capillary fringe
{wiki=Capillary_fringe}
The capillary fringe is a zone in the soil or sediment that lies above the water table but is still saturated with water due to capillary action. This phenomenon occurs in porous materials, such as soil, where water is pulled upward from the groundwater level into the spaces between soil particles or rock due to surface tension. In the capillary fringe, water is held in place against the force of gravity, primarily through adhesive and cohesive forces.
