Concept:

Aquifer: 

It is an underground geological formation that contains water and a sufficient amount of water can be extracted economically using water wells. It generally comprises layers of sand and gravel and fractured bedrock.

  • Unconfined Aquifer: When the water table serves as the upper boundary of the aquifer, the aquifer is known as an unconfined aquifer. The unconfined aquifer is also known as the water table aquifer and phreatic aquifer. An impervious layer is generally served as the bottom boundary of an unconfined aquifer and the top layer is not confined.

  • Confined Aquifer: An aquifer that is bounded by two impervious layers at the top and bottom of the aquifer is called a confined aquifer. The confined aquifer is also known as a pressure aquifer or artesian aquifer. The top and bottom layers of a confined aquifer are generally impervious.

Aquiclude:

  • It contains a large amount of water in pores, but Impermeable to the flow of water (extraction of water is very difficult). It may be considered as close to water movement.
  • A good example of aquiclude is clay.

Aquitard:

  • Aquitard form by that material through which the only seepage is possible but extraction of water is not so easy (Insignificant yield) as in aquifer.
  • A good example of aquitard is silty clay material.
