A storm surge barrier is a structure designed to protect coastal areas from flooding caused by storm surges, which are rising sea levels during storms. These barriers can be gates or walls that close off waterways, preventing ocean water from inundating land during severe weather events. They are often strategically placed at river mouths or estuaries to provide maximum protection. These barriers are crucial for safeguarding infrastructure, homes, and ecosystems in vulnerable regions. By controlling water flow, they help mitigate the impact of storms, reducing damage and enhancing community resilience. Examples of such barriers include the Maeslantkering in the Netherlands and the Thames Barrier in London.
