How the Thames Barrier Works
The barrier is a series of ten separate rotating gates positioned end-to-end across the river.
Each gate is attached to concrete piers that house the operating equipment.
When there are high tides, with high waves caused by storms, the gates are lifted to stop water travelling up the Thames estuary.
