In the saturated zone water fills all pores, whereas in the unsaturated zone air and water fill pores. There are nn underground rivers, unless it is in a cave. The water table recharges when there is a wet period. Aquifer ---- where water is stored underground. It has to be porous (holes in the rock) Permeability is the ability of a rock to transmit fluid.

Metamorphic and igneous rocks must have secondary porosity in order to.
