The common name is "Artesian Well"
When the pressure of rock layers pressing on an aquifer makes the water in the aquifer rise to the surface without pumping, it is called artesian pressure. This natural pressure occurs when a confined aquifer is sandwiched between impermeable layers, causing the water to flow upward due to the pressure gradient.
artesian well
Artesian spring. This occurs when an aquifer is confined between impermeable rock layers, creating pressure that forces the water to rise naturally to the surface without the need for pumping.
This process is called artesian flow or artesian well. It occurs when confined groundwater is under pressure and flows upward to the surface due to the pressure gradient created by the surrounding rock layers.
A non-confined aquifer is an aquifer where the water table is at atmospheric pressure, allowing water to flow freely in and out of the aquifer. This type of aquifer is typically located close to the surface and is recharged by precipitation. Non-confined aquifers are more susceptible to contamination compared to confined aquifers.

This process is called artesian flow. It occurs when the pressure from surrounding rock layers forces water in an aquifer to rise above the level of the aquifer, sometimes to the Earth's surface, without the need for pumping.
