Aquifer - an underground rock structure from which water is extracted

Reservoir - the general storage location name for any material

Transfer rate - the volume of material moves from one reservoir to another

Precipitation - condensation of atmospheric water vapour that reaches the Earth's surface in any liquid or solid form

Throughflow - sideways movement of water in the ground

Interception - precipitation that doesn't reach the ground landing on vegetation
