Experts confident water levels will recede

Q WATER levels nationwide should recede reasonably quickly once the current spate of extreme weather ends, experts say.

Levels are higher than normal, with readings from one monitoring station in Kilkenny suggesting they are at historic highs, the Environmental Protection Agency (EPA) said.

It added that data showed levels were "elevated" in some parts of the country, and were likely to have become higher due to heavy rain.

However, the Geological Survey of Ireland (GSI) said that Ireland's geology resulted in water flowing quickly through the ground and to discharge points in rivers and the sea, making flooding from this source unlikely. Groundwater flooding occurs when rainfall is significant enough to cause the water table to breach the surface.

The situation is in stark contrast to the UK, where there are big fears that groundwater floods will last for months. The geology in Britain means that water is stored for longer.
