Dublin Port Company (DPC), in partnership with University College Dublin (UCD), has launched an innovative initiative to enrich biodiversity along the Great South Wall, marking a significant advancement in eco-engineering and sustainability practices.
While artificial structures like seawalls and rock armour have been essential for protecting ports worldwide, they often lack the biodiversity of natural rocky shores, posing challenges for marine ecosystems. Recognising this, UCD researchers collaborated with DPC to pioneer a solution that combines ecological principles with engineering expertise.
Central to this effort is the deployment of large habitat units along the Great South Wall, strategically chosen for their potential to support marine life. These units, incorporating a natural topography design inspired by Ringaskiddy, Co Cork, represent a pioneering achievement in eco-engineering.
The design process drew from a comprehensive study conducted under the Ecostructure project, with Dublin Port’s pivotal involvement. This study evaluated 32 natural rocky shores and 32 artificial shoreline sites across Ireland and Wales, assessing both biological diversity and physical topography. Leveraging advanced techniques like photogrammetry, the project team developed 3D models to guide the creation of engineering-standard habitat units and wall panels.
Crucially, these habitat units integrate natural topography into eco-friendly concrete, reducing carbon footprint while maximising biodiversity potential. Collaboration with industry partners CubEX and MODULAR Cubed underscores the fusion of academic research with practical application.
UCD researchers will conduct thorough monitoring over the next two years to evaluate the effectiveness of these habitat units in enhancing marine biodiversity. By studying diverse species, including invertebrates and fish, the project aims to uncover valuable insights into large-scale eco-engineering approaches.
Despite losing its title as the world’s longest seawall, the Great South Wall retains its significance as one of Europe’s longest, symbolising a legacy of maritime engineering.
