Detailed Shoreline Combined Wave Climate and Water Level Conditions (Galway City CWWS 2020)

Abstract: This dataset shows the Detailed Shoreline Combined Wave Climate and Water Level Conditions for the Galway Coastal Area Potentially Vulnerable to Wave Overtopping (CAPOs). Joint probability water level and wave climate condition tables have been produced for the present day scenario, Mid-Range Future Scenario (MRFS), High End Future Scenario (HEFS), High + End Future Scenario (H+EFS) and High++ End Future Scenario (H++EFS) which represent a 0.5m, 1.0m, 1.5m and 2.0m increase in sea level respectively. For each AEP from 50% to 0.1%, six combinations of wave climate and water level conditions were produced representing the complete joint probability range. The outputs of these studies are considered suitable to inform the detailed evaluation of the risk associated with wave overtopping, any resulting coastal flooding (both now and in the future) and the detailed design of measures to mitigate and manage any such identified coastal flood risk.

Purpose: The Galway City Coastal Wave and Water Level Modelling Study (CWWS) 2020 provides an improvement and update to the wave climate and water level combinations of known Annual Exceedance Probability (AEP) presented as output from Phase 2 of the Irish Coastal Wave and Water Level Modelling Study (ICWWS) 2018 for the Galway Coastal Area Potentially Vulnerable to Wave Overtopping (CAPO). The outputs from this study may inform the evaluation of the risk associated with wave overtopping, any resulting coastal flooding (both now and in the future) and the detailed design of measures to mitigate and manage any such identified coastal flood risk.
