§ Dr. CableTo ask the Minister of Agriculture, Fisheries and Food what assessment has been made of the impact of global warming and sea level rise on the risk of the Thames Barrier being unable to withstand future storm surges. [138498]
§ Mr. MorleyThe Thames Barrier is the largest component of the complex system of gates, walls and embankments which form the tidal barrier to London and the Thames Estuary. The Barrier is a robust and flexible installation with a design based on rates of sea level rise predicted in the 1970s which were higher than those currently anticipated. It provides London with a high level of protection from tidal flooding and with normal care and maintenance should continue to do so until at least the latter half of this century. Even then, although the Barrier may need to be closed more frequently, it will continue to fulfil its primary function.
The Environment Agency is currently developing its tidal defence strategy for the next 100 years, with several studies already in progress.
