Scientists have been investigating the effects of a 7m-high wave
travelling up the Thames, using computer simulations.
The wave was produced by a "virtual storm" as part of a £6.5m project
at the UK Met Office.

Researchers say the work is crucial to our understanding of how storms
cause dangerous flooding around the UK and the quest to improve
forecasting.
