Maximizing the beneficial environmental effects of tropical hybrid shorelines - (MaxBETH)
As demand for coastal protection continues to grow, this project evaluates how hybrid shorelines—combining coastal vegetation with hard engineering structures—can improve resilience, especially amid the impacts of climate change and human activities.
Research Goals
- Quantify the added benefits of integrated approaches by comparing traditional coastal engineering (“grey solutions”) with natural coastal ecosystems (“green solutions”).
- Evaluate the opportunities and challenges of scaling up hybrid shoreline solutions.
- Investigate how hybrid shorelines affect key biophysical processes.
Why This Matters
- Supports the development of alternative coastal protection strategies to tackle long-term sea-level rise.
- Integrates nature-based solutions to help mitigate climate change (e.g., mangroves and seagrasses sequestering carbon).
- Generates both fundamental and applied knowledge on eco-engineering and hybrid shoreline solutions.
- Provides insights for upscaling designs, maximizing hybrid solution benefits, and developing ecological models and decision-support tools.
Latest Research Highlights
- Surveyed biotic communities in headlands and bays versus linear seawalls, providing baseline data to inform future shoreline designs.
- Assessing the feasibility of constructing artificial reef structures using 3D construction printing to enhance coral larval recruitment and habitat complexity.
- Mapped intertidal waterways and identifying potential sites for shoreline softening and ecological enhancement interventions.
- Developing physical and statistical models to quantify how hybrid shorelines affect sediment resuspension, gas transfer, and ecosystem functions, supporting informed coastal engineering decisions.
- Assessing the ecological impacts of hybrid solutions by comparing biodiversity, carbon and nutrient cycling, as well as primary productivity across natural, hybrid, and hardened shorelines.
