Giant Sausage To Protect Dawlish Warren


There are some excellent opportunities for fieldwork or class-based studies using recent decisions made to control flooding in the Exe estuary in Devon. The Environment Agency and Teignbridge District Council are working together on a new beach management scheme at Dawlish Warren, which will get under way in early 2017. Flood defence experts are planning to bury a giant barrier in the dunes – likened to a sand-filled 400 metre long sausage – to allow the spit to continue to act as a barrier to storm waves, and stop the Exe estuary from flooding.

Despite a package of emergency restoration through 2016, the groynes are deemed no longer up to the job – leaving the spit at risk of being breached as a result of rising sea levels and severe winter storms.

 If this happened, it would increase the risk of flooding to the London to Penzance railway line and thousands of homes in estuary communities such as Starcross, Lympstone and Exmouth.
