-- Name -- Aquifer
A wet underground layer of water-bearing permeable rock or unconsolidated materials (gravel, sand, silt, or clay) from which groundwater can be usefully extracted using a water well. -- Description -- An underground geological formation able to store and yield water.

aquiferType AkviferType The type of aquifer. -- Description -- Water in an Aquifer is, or is not, under pressure. Based on that unconfined, confined, artesian, or subartesian types are distinguished.
mediaType AquiferMediaTypeValue The classification of the medium in which the groundwater flow occurs.
isExploited Boolean Indicates if groundwater from aquifer is exploited by wells or intakes
isMainInSystem Boolean Indicates if aquifer is the main useful aquifer in the aquifer system
vulnerabilityToPollution QuantityValue An index value or interval of values determining the potential degree of aquifer risk arising from the geological structure, hydrogeological conditions and the existence of real or potential source of contamination. -- Description -- A single value should be used if it is determined directly from the DRASTIC method. If attribute data comes from another data source which is expressed by categorized items, for example: low, moderate or high, interval should be used expressed by lowest and highest value of category. EXAMPLE: ‘Moderate’ means interval from 101 to 140.
permeabilityCoefficient QuantityValue The volume of an incompressible fluid that will flow in unit time through a unit cube of a porous substance across which a unit pressure difference is maintained. -- Description -- The parameter represents the hydraulic conductivity of a rock container. Describes the ease with which water can move through pore spaces or fractures. It depends on the intrinsic permeability of the material and on the degree of saturation. NOTE: Because of their high porosity and permeability, sand and gravel have higher hydraulic conductivity than clay or unfractured granite aquifers.
storativityCoefficient QuantityValue The ability of an aquifer to store water.
hydroGeochemicalRockType HydroGeochemicalRockTypeValue The rock type with respect to the soluble rock components and their hydrogeochemical influence of groundwater. -- Description -- Defines the prevailing geochemical character of natural groundwater within the Aquifer.
