| Groundwater |
All subsurface
water found in the pore space of soils and rocks. |
| Capillary Water |
Moisture held in the soil by surface tension and hydrogen bonding
with soil materials.
|
| Gravity Water |
Water in excess of capillary water that is able to flow down through
a permeable earth layer.
|
|
Porosity
|
The amount of space between rock and soil particles (affects water
storage)
|
|
Permeability
|
The ability of soil or rock to allow water to pass through (affects
ground water movement)
|
|
Zone of Aeration
|
Upper soil/rock level in which pore space is a combination of capillary
water and air
|
|
Zone of Saturation
|
Lower soil/rock level in which pore space is full of water.
