Coastal erosion is a major environmental issue affecting many coastal regions, including Arattupuzha in Kerala, where the shoreline is rapidly receding due to strong wave action and sediment transport. This project proposes a sustainable erosion mitigation strategy using a combination of T groynes and a seawall. The structural performance of these protective measures was evaluated through numerical simulations using ANSYS software. Key parameters such as velocity vectors, turbulence kinetic energy, and streamline flow were analysed to understand the hydrodynamic behaviour around the structures. The study compared the performance of T groynes and conventional straight groynes. Results indicated that T groynes are more effective in stabilizing the shoreline and retaining sediment, offering better performance in wave energy dissipation. The addition of a seawall behind the groynes provides an extra layer of defensive measure, reducing direct wave attack and preventing further coastal retreat. This integrated approach not only enhances the protection of the shoreline but also ensures the long-term safety of nearby communities. The findings underline the value of advanced modelling tools in coastal engineering and provide a strong foundation for future design improvements based on site-specific environmental data.
