Vesikerroksesta

Vesikerros is a Finnish term that translates to "water layer" or "water horizon." It refers to a layer of groundwater that is situated above an impermeable stratum, such as a clay or bedrock layer. This impermeable layer prevents the water from percolating further down into deeper aquifers. Consequently, the water in a vesikerros is confined, meaning it is under hydrostatic pressure. The presence of a vesikerros is a significant factor in hydrogeology, influencing the availability and movement of groundwater. These layers can serve as important sources of water for wells, particularly in areas where deeper aquifers are scarce or contaminated. The characteristics of a vesikerros, such as its thickness, permeability, and water quality, depend on the geological composition of the surrounding soil and rock formations. Understanding the location and properties of vesikerrokset is crucial for sustainable groundwater management and for planning infrastructure projects that might interact with groundwater resources. They can also play a role in surface water hydrology, as they may discharge into streams, lakes, or wetlands.
