A Multi-tool Approach, Including Citizen-Science, to Study Beach and Dune Morphodynamics in Co. Cork, Ireland
摘要
In the complex context of climate change and sea level rise, Co. Cork’s coastline (Ireland) is exposed to high risks of coastal erosion and flooding. As part of the European A-AAgora project, a multi-tool approach has been developed to better understand coastal processes in action and the role of coastal protection structures at different study sites in East and West Cork. To support better decision-making, we combined methods such as DGPS surveys, a static camera video and citizen-science (e.g. CoastSnap and Maptionnaire). Preliminary topographic results show the morphological evolution of Pilmore and Inchydoney beaches under various hydrodynamic forcing, including high energy events. Data collected at Pilmore will also allow us to compare different management solutions and their efficiency in protecting the shoreline. Inchydoney beach is, in contrast, a more natural environment, where the combination of the complex local geology and hydrodynamics from the Atlantic drives significant morphological changes. Although results extracted from DGPS surveys give a good idea of sediment transport patterns within the system, further work is needed to better understand physical processes under various hydrodynamic conditions (such as low and high-water levels, storms and calm weather) using video images. To gather more data and tackle coastal challenges, we also work with citizens and communities using education and survey tools such as Maptionnaire and CoastSnap. These tools facilitate an active and participatory approach to community engagement, ultimately improving our understanding of coastal processes and ensuring a more sustainable future for coastal areas and communities.
