The zone is essentially a connecting link between a near-ground surface region and the near- water-table region through which infiltrating fluids must pass Capillary zone a capillary zone extends from the water table to a height determined by the capillary rise that can be generated in the soil. The capillary band thickness is a function of soil texture and may fluctuate not only from region to region but also within a local area Saturated zoneFigure 1.2 Different types of aquifers (from Kruseman and de Ridder, 1990) Intermediate zone This belt extends from the bottom of the soil-water zone to the top of the capillary fringe and may change from non-existence to several hundred meters in thickness.
