Why build a barrage between Cardiff and Weston Super Mare?

Building a barrage between Cardiff and Weston-super-Mare would create a barrier to control tidal flows, potentially generating renewable energy through tidal power. It could also help protect coastal areas from flooding and erosion, improving resilience against climate change. Additionally, the project could enhance local marine habitats and promote economic development through increased tourism and leisure activities. Overall, such a barrage would aim to balance environmental sustainability with regional economic benefits.
