artesian well
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.
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.
When the pressure of rock layers pushes water from an aquifer up to the Earth's surface, it is called artesian flow. This natural process occurs when there is enough pressure in the aquifer to force the water upward through a well or borehole without the need for a pump.
Artesian wells rely on natural pressure within the underground aquifer to bring water to the surface without the need for pumping. This pressure is created by the weight of the overlying rock layers that confine the water in the aquifer. When a well is drilled into the confined aquifer, the pressure forces the water up through the well to the surface.
