Predicting Sea Levels and Sea Level Extremes for Ireland | PI | Science Foundation Ireland / Frontiers for the Future PROJECT | Rising seas increase the vulnerability of cities and associated infrastructure that line the coastline of Ireland because of higher extreme sea levels (and flooding), coastal erosion, salinization of surface and ground waters, and degradation of coastal habitats. Armed with statistical knowledge of how sea levels have been changing in the 20th and 21st century, future links between mean sea-level and sea level extremes due to storm surges and wave climate can be established, which are vital to inform decision making related to flood risks. For this project, we have identified three main components necessary for providing estimates of current and future sea levels and sea level extremes around Ireland: (1) Establish links between sea-levels and climate using instrumental records of Irish sea-level changes; (2) Estimate extreme sea-level probabilities at high spatial resolution for select locations along the Irish coastline considering influences of sea-level rise, storm surges and waves; (3) Combine outputs from (1) and (2) to provide projections of extreme sea levels and corresponding return periods under different climate scenarios. Outputs will contribute to a stakeholder-focused, user-friendly web-application, interactive maps, R software and databases which respond to Ireland’s need for future sea-level and extreme sea-level projections and their interpretation. | 01-DEC-21 | 30-NOV-24 | 258529 | |
