Description
-
An aquifer is a rock formation that stores water and can release it for use, functioning as an underground reservoir. There are two main types: unconfined aquifers, which are directly connected to the atmosphere and fluctuate in water levels due to recharge and discharge, and confined aquifers, which are surrounded by impermeable layers and maintain water under pressure. Water can flow from unconfined aquifers to the surface, creating springs, while base flow from these aquifers contributes to stream flow, especially during dry seasons. Perched aquifers are small, limited extensions of unconfined aquifers, retaining groundwater above an impermeable layer.
