ABSTRACT
This research focuses on shore storm risk mitigation using a modular coastal defence system. Solution consisting of high-tensile steel mesh modules filled with rocks and securely fastened with tension rods. This system is implemented in Beesands (U.K.). Using preliminary laboratory physical modelling, 32 tests compared the performance of the flexible high tensile mesh modules against traditional rock armour, using wave run-up as the primary performance indicator. Results showed that modules consistently reduced run-up by an average of 15% compared to traditional rock armour structures. Wave reflection and oscillation were assessed using the mean spectral ratio index, which was significantly lower for novel modules compared with boulder armour, indicating better behaviour in wave energy dissipation. A carbon footprint analysis based on the case study revealed that flexible modules emitted 20–30% less CO₂ than rock armour, while concrete revetments produced twice the rock armour emissions.
