The Thames Barrier, completed in 1984, primarily serves to protect London from flooding due to storm surges and rising sea levels. While it effectively mitigates flood risks, its operation can disrupt local ecosystems, particularly aquatic habitats and sediment transport in the Thames River. Additionally, the barrier's construction involved significant alterations to the river's natural flow and sediment dynamics, which can impact fish populations and other wildlife. Overall, while it provides essential flood protection, it also presents challenges for maintaining ecological balance in the river system.
