Effective porosity is defined as the percentage of inter connected pore space; it is less than total porosity. Although the volume of contained in an aquifer is of interest, of more concern is how much water can actually be released from storage, per unit area of aquifer and per unit change in total head.
Porosity represents the volume of water that an aquifer can hold, but it does not indicate how much water the aquifer can yield
Take an example of a sponge below;
If you were to soak two cups of water in a sponge, evenif you squeeze with a machine, you will never be able to get out two cups of water exactly
