Transatlantic collaboration aims to boost resilience of sea walls

Envirotec Magazine

Around 148 million people worldwide are exposed to coastal flooding events, which are predicted to surge in frequency and severity in the coming decades as climate change drives sea levels higher. It’s hoped this will highlight areas where the design and resilience of sea walls could be strengthened.
