Web3.2 Controls on Permeability and the Range of Permeability Values in Nature Intuitively, it is clear that permeability will depend on porosity; the higher the porosity the higher the permeability. However, permeability also depends upon the connectivity of the pore spaces, in order that a pathway for fluid flow is possible. WebPermeability is a measure of the interconnectedness of pores. The connection between pore spaces allows groundwater to flow through the sediment or rock. The combination of water storage (porosity) and flow (permeability) makes a good aquifer—a rock unit or sediment that contains usable groundwater.
