Akviferisse
Akviferisse is a term used in some contexts, particularly in Estonian, to refer to an aquifer. An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt) from which groundwater can be extracted using a water well. These geological formations must be permeable enough to allow significant quantities of groundwater to move through them. Aquifers are essential sources of fresh water for drinking, agriculture, and industry. The water within an aquifer is replenished by precipitation that percolates down through the soil and rock layers. The rate of replenishment, known as recharge, is a critical factor in determining the sustainability of an aquifer as a water source. Over-extraction of water from an aquifer can lead to a decrease in the water table, land subsidence, and saltwater intrusion in coastal areas. Understanding and managing aquifers is a key aspect of hydrogeology and water resource management.
