Thames Estuary

What happened?

  • Higher mean sea levels, more  storms, increasing tide amplitude, tilting of British Isles (southeastern corner tipping downwards) and settling of London on its bed of clay
  • 60 cm rise per century
  • Surge tides are a threat and occur under meteorlogical conditions:
  • When a trough of low pressure moves across the Atlantic towards the British Isles, the sea beneath it rises above the normal level, this thus creatng a 'hump' of water which moves eastwards with the depression

Soloutions/failures

  • Thames Barrage important step in reducing flood risk and protecting central London
  • Completed in 1984
  • Thames gateway proposal to allow more development along the shore of the Esturary, flood risk comes to fore
