Question

what is artesian well? Please give me the answer by shortly.​

Answer 1

Answer:

An artesian aquifer is a confined aquifer containing groundwater under positive pressure.An artesian aquifer has trapped water, surrounded by layers of impermeable rock or clay which apply positive pressure to the water contained within the aquifer.If a well were to be sunk into an artesian aquifer, water in the well-pipe would rise to a height corresponding to the point where hydrostatic equilibrium is reached.

Answer 2

An artesian aquifer is a confined aquifer containing groundwater under positive pressure. An artesian aquifer has trapped water, surrounded by layers of impermeable rock or clay which apply positive pressure to the water contained within the aquifer. If a well were to be sunk into an artesian aquifer, water in the well-pipe would rise to a height corresponding to the point where hydrostatic equilibrium is reached.

Artesian aquifer scheme:

1. Aquifer

2. Impervious strata

3. Infiltration area

4. Artesian well

5. Saturation level

6. Subartesian well

7. Artesian spring

A well drilled into such an aquifer is called an artesian well.If water reaches the ground surface under the natural pressure of the aquifer, the well is termed a flowing artesian well.

Fossil water aquifers can also be artesian if they are under sufficient pressure from the surrounding rocks, similarly to how many newly tapped oil wells are pressurized.
