Saturaatiovyöhykkeessä
Saturaatiovyöhykkeessä, known in English as the saturation zone, is a geological and hydrological term referring to the portion of the subsurface where all pore spaces are completely filled with water. This zone lies below the unsaturated zone, also known as the vadose zone, where pores contain both air and water. The upper boundary of the saturation zone is the water table, which is the level at which the pressure of the groundwater is equal to atmospheric pressure.
In the saturation zone, groundwater flow is primarily governed by hydraulic gradients and the permeability of
The saturation zone is a crucial component of the hydrological cycle, as it stores and transmits groundwater.
