Get down to the Thames Barrier as the Environment Agency carry out the annual test closure holding back the tide

The Thames Barrier is one of the largest movable flood barriers in the world. The Environment Agency runs and maintains the Thames Barrier as well as London’s other flood defences. Once a year, the Environment Agency holds a full tide test closure of the Thames Barrier.

During the test closure, the Thames Barrier gates rotate 90 degrees into the fully closed defence position, stopping the tide from going into London. As the tide continues to rise, a higher level of water will build up downstream of the Barrier creating different water levels on either side of the gates.
