Midleton Flood Relief Scheme, Co. Cork

Holistic approach to flood assessment by addressing all four sources of flooding

Midleton is located at the confluence of the Owenacurra and Dungourney Rivers, 24km east of Cork City, within Cork Harbour. Midleton has a strong history of flooding over the past 40 years.

In recent years, the most notable flooding events occurred in November 2000, October 2004, June 2012, July 2013, January 2014, February 2014, October 2014, December 2015 and January 2016. These events included both fluvial and tidal events, as well as groundwater flooding and pluvial flooding events.

Following the severe flooding event of winter 2015/16, Arup was commissioned by Cork County Council to undertake an emergency review of the flood event. The review, amongst other things, highlighted the significant groundwater component of the flooding and, thus, the importance of understanding the hydrogeology of the Midleton area to ensure that any future flood relief measures designed for the Midleton area are effective.

Following a subsequent public procurement competition, Arup was successful in being appointed by Cork County Council to develop a viable, cost-effective and sustainable flood relief scheme that addresses all four sources of flood risk, namely; fluvial, tidal, groundwater and pluvial flooding. The aim of this scheme is to minimise risks to the existing community, social amenity, environment and landscape character.

Arup recently presented an overview of the project to elected representatives in the area and also held a Public Information Day (PID) in Midleton where the general public and all interested parties were invited to give their opinions. The PID was very well attended and initial feedback was largely positive with the majority welcoming the scheme.

Work to date has focused on data collection and review and preparation of a number of surveys, including a hydrometric river survey, LiDAR and Geophysics survey. The project is currently at data collation stage and construction is estimated to commence in 2020. A constraints and environmental assessment will run in parallel to the engineering study.
