Flood mapping

Flood maps are one of the main outputs of the study. Flood maps have been produced for the Rivers Lee, Glashaboy, Owenboy, Owennacurra and Tramore, their tributaries, and Cork Harbour. Flood maps have been prepared in different formats, each designed for various end uses, and representing both current and future flood risk.

Flood maps provide valuable information regarding flooding within the catchment. These have been used within the study to identify areas of significant flood risk and to inform the development of flood risk management options. These flood maps can also be used to:

A number of floodmapping formats have been developed for the Lee CFRAMS to serve a number of purposes. These flood maps include flood extent, flood depth, flood velocity, flood hazard and flood risk. Further information on some of these map formats is provided below.

Flood extent mapping.

Flood extent maps illustrate the estimated area inundated by a particular flood event for a given annual exceedence probability (AEP). For more information on flood extent mapping please click on the following link

Flood hazard mapping.

Flood hazard mapping shows the potential danger arising from a particular flood event. More information on flood hazard mapping mapping can be found at the following link
