The purpose of the schemes was to improve land for agriculture, to ensure that the 3 year flood was retained in bank this was achieved by lowering water levels during the growing season to reduce waterlogging on the land beside watercourses known as callows. The Scheme, which comprises construction of demountable flood defences at the underpass along with localised embankments is expected to provide protection against an estimated 100-Year flood (1% Annual Exceedance Probability) in the fluvial region and the 200-Year flood (0.5% Annual Exceedance Probability) tidal event for 37 properties. The Scheme is currently at design stage. Localised widening of the River Boherroe from a 4m to a 5.5m wide channel along the 150m reach between the Bridge road bridge and R556 road bridge.

Layer Information These maps are focussed primarily (but not entirely) on flooding at seasonally This is also referred to as an Annual Exceedance Probability (AEP) of 0.5% or 0.1%. These probabilities may also be expressed as odds (e.g. The Wad River Flood Alleviation Scheme was initiated in 2009 following two major flood events in this catchment in August 2008 and July 2009.
