WebbThis process can be applied either for the case where the whole soil mass is subjected to the water seepage, or for the case where the seepage occurs only in a portion of the soil mass, which is delimited by a phreatic surface. For the last case, the BEM should be applied in an iteractive procedure to find the position of the phreatic surface. WebbNow that we know what the zone of aeration and the zone of saturation are, let’s list out the differences between them. 1. The zone of aeration is located immediately beneath the root-zone.

The phreatic zone, saturated zone, or zone of saturation, is the part of an aquifer, below the water table, in which relatively all pores and fractures are saturated with water. Above the water table is the unsaturated or vadose zone. The phreatic zone size, color, and depth may fluctuate with changes of season, and during wet and dry periods. Depending on the characteristics of soil particl…
