It is hoped that new outings may be offered later this year (2021) either on the West Cork coast or in Cork City.

  • 26 March 2021. VIDEO LECTURE: Cork’s Underlying Problem. Cork’s long history of flooding is discussed in a new presentation, which can be found at https://www.leeforum.org/video-lectures. Three types of flooding impact the city centre: tidal surges, river floods and groundwater flooding. Moreover, there are numerous flood risks that cannot be quantified. For example, the contribution from groundwater flooding to the city’s problem is not well understood. The talk presents new evidence for perched water in local aquifers within man-made filling that has been added to the former estuary. Thus tidal flows, which have been held up by estuarine mud since the prehistoric period, continue to appear in the city streets during flood events. There are also several major canals, now culverted, that date back to the medieval period. Yes, its complicated!
  • March 2019. Ground and groundwater conditions at Cork... The former landscapes of the city are presented in this report. Again, the research is based on historical maps, archaeological records and engineering boreholes: https://www.leeforum.org/post/ground-groundwater-conditions-at-cork-and-implications-for-the-lower-lee-flood-relief-scheme-opw The review, which includes several new plans, indicates that there are many factors that impact flooding of the city centre, and that these factors make the implementation and operation of direct defences problematic (parapet walls, cut-off measures and pumping stations). Therefore, in the opinion of the author, the current OPW proposal is over-engineered and represents an experiment that is likely to fail. Reference to the report should be made as: Ground and groundwater conditions at Cork: Implications for the Lower Lee Flood Relief Scheme. Anthony Beese. Special Report No. 713/5D for Save Cork City. March 2019.
