Promoting hybrid solution resilience by optimising hydrodynamical and structural influences on coral larval attachment to reefs and sediment clustering amid seagrass v2-p5

Promoting hybrid solution resilience by optimising hydrodynamical and structural influences on coral larval attachment to reefs and sediment clustering amid seagrass

This project develops sustainable coral-infused hybrid coastal protection systems. By optimising these structures, it aims to reduce the effects of waves and sediment displacement on coral larval settlement.

Research Goals

  • Assess the effectiveness of artificial reefs and seagrass arrays in dissipating wave energy and managing sediment movement.

  • Predict sediment patterns and the forces affecting suspended and settling coral larvae under different flow conditions and structural environments.

  • Develop best practices for selecting, designing, and placing structures to minimise obstruction or dislodgement of coral larvae.

Why This Matters

  • Seawalls are a key component of Singapore’s strategy to address rising sea levels and stronger storm surges.

  • Their surfaces have been found to support coral growth, contributing to hybrid coastal protection solutions.

  • The sustainability of these solutions depends on promoting the survival of coral populations.

  • Models developed in this project identify factors that limit coral larval settlement and growth.

  • Insights from the models guide the optimisation of seawall design and configuration to enhance coral survival.

Latest Research Highlights

Modular Breakwater Evaluation

  • Developing a numerical wave flume to test modular breakwater designs and optimise placement for supporting seagrass growth and coral larval settlement. This will be validated against downscaled ocean basin tests and then applied to full-scale simulations.

Seagrass Behaviour and Flow Interactions

  • Assessing seagrass material properties and deformation under flow to improve simulation accuracy and guide future array designs and field trials. This enables a more accurate representation of seagrass behaviour under various hydrodynamic conditions.

Coral Surface Roughness

  • Studying surface roughness effects on mixing and coral larval settlement to inform laboratory experiments and future reef design and deployment. This permits higher-fidelity resolution of interactions between larvae and flow near artificial reef surfaces.
