The Severn-A Lost Landscape
The Severn' is no stranger to change. Twice daily its tides sweep the largest flow of water of any river in the UK.
Before the Severn, where its tidal reach is, was once a shallow sea and for aeons prior to that it was desert.
In the last seventy years it has been radically altered.
Sea defences and drainage have turned flood plains into fields and housing. Bridges,tunnels and motorways span the dangerous currents and mud. Old lifestyles and customs are now folk memories and an ancient landscape is now shallowly flooded by a seventy year old replacement.
A future of global warming and rising sea levels promises further changes.
There are however still clues anchored in its landscape to how it was in the past and how it will be in the future.
