A new Thames flood barrier at Dartford was proposed by the Environment Agency last week as part of a range of initiatives to protect London from flooding over the next 100 years.
The Agency believes that the existing Thames Barrier will continue to provide protection to London until at least 2070 –40 years longer than its intended design life.
To replace it the Agency has proposed a barrier further downstream at Long Reach to be operational by 2075.
The findings are the result of a six-year investigation led by the Agency into the future of flood risk management within the Thames estuary.
A consultation on the Thames Estuary Plan – or TE2100 – unveils the recommended options to manage the threat of tidal flooding for London and the Thames estuary through to the year 2100. “This plan has looked at the worst case scenario for climate change,” said agency chief executive Paul Leinster. “If sea levels are found to be rising faster then expected then we are prepared and have identified the necessary solutions.”
