Thames Estuary 2100 (TE2100)
How the Environment Agency and its partners are protecting the Thames Estuary from flooding caused by climate change.
We need to adapt to climate change along the Thames Estuary. As sea levels rise and defences get older, the risk of flooding from the Thames increases.
The Thames Estuary 2100 Plan outlines how to manage this risk. Developed by the Environment Agency and its partners, the Plan sets out a vision for the estuary’s future.
Map and policy units
We divide the Thames Estuary into 23 areas called ‘policy units’. Each policy unit has a page that explains how to manage flood risk in that area.
Use the Thames Estuary 2100 map to find your local policy unit.
