Porosity VS. Permeability
Permeability: is a measure of the ease movement water can move through a porous rock.
Water table is the level below which the ground is saturated with water.
The zone of aeration is the region between the earth's surface and the water table.
Zone of saturation is the area in an aquifer, below the water table.
A Aquifer is an underground layer of water-bearing permeable rock, fractures or soft materials (soil) from which groundwater can be extracted using a water well.
Aquiclude is a impermeable layer that restricted the water flow.
Effects of groundwater Overuse
Groundwater is the largest source of usable, fresh water in the world. In many parts of the world, especially where surface water supplies are not available.Pumping water out of the ground at a faster rate than it is replenished over the long-term causes similar problems.
Groundwater depletion is primarily caused by sustained groundwater pumping. Some of the negative effects of groundwater depletion:
Lowering of the Water Table.
Reduced Surface Water Supplies.
Water Quality Concerns.
