2015/2016 Surface Water Flood Map 1:20,000 Ireland (ROI) ITM

Groundwater is the water that soaks into the ground from rain and can be stored beneath the ground. Groundwater floods occur when the water stored beneath the ground rises above the land surface. The Winter 2015/2016 Surface Water Flooding map shows fluvial (rivers) and pluvial (rain) floods, excluding urban areas, during the winter 2015/2016 flood event, and was developed as a by-product of the Historic Groundwater flood map. The map is a Vector Dataset. The floods are shown as polygons. Each polygon has info about the type of flood, the data source, and the area of the flood.The flood extents were made using remote sensing images, which are covered any site in Ireland every 4-6 days. As such, it may not show the true peak flood extents.
