Powerful waves can be a big problem for the UK coastline so a lot is done to defend the land against the sea.

Now, a new project will be turning 27 kilometres of Scotland's coastline into a living laboratory to help.
Some Edinburgh school pupils have been telling Newsround what they've been trying to do.
