Groundwater is the water that soaks into the ground from rain and is stored beneath the ground. An aquifer is a body of rock and/or sediment that holds groundwater. The process of rain filling up an aquifer is called \u2018recharge\u2019. <\/SPAN><\/SPAN><\/P>

The Groundwater Recharge map shows the amount of rainfall which reaches the stores of groundwater (the \u2018aquifers\u2019) across Ireland. The amount of recharge was calculated over the period 1981-2010 and then averaged to give a yearly amount.<\/SPAN><\/SPAN><\/P>

Geological information is interpreted by hydrogeologists to create the map includes soil drainage, subsoil type, subsoil permeability, subsoil thickness, groundwater vulnerability and aquifers. The amount of rain falling on the land minus how much of that rain is taken up by plants is also a factor that determines how much groundwater recharge there is at a particular location. This is known as the \u2018effective rainfall\u2019.<\/SPAN><\/SPAN><\/P>

Different combinations of the geological factors give 24 hydrogeological scenarios. There is a \u2018recharge coefficient\u2019 for each scenario, which is the percentage of the \u2018effective rainfall\u2019 that may become groundwater recharge. Using ArcGIS software, the data are merged to create areas on a map to show the recharge. Please read the lineage for more detail.<\/SPAN><\/SPAN><\/P>

This map is to the scale 1:40,000. This means it should be viewed at that scale. When printed at that scale 1cm on the map relates to a distance of 400m.<\/SPAN><\/SPAN><\/P>

It is a vector dataset. Vector data portray the world using points, lines, and polygons (areas). The recharge data is shown as polygons. Each polygon holds information on:<\/SPAN><\/P>

Average Recharge (mm/yr) - average annual recharge to the groundwater aquifer across that polygon<\/SPAN><\/SPAN><\/P>
