I did not thought about coastal erosion, but it is a good consideration.
For this problem, wouldn't channelling the seawater inland be more

With the UK being blessed with sea, I would have thought we may take the

I rather think mangroves might object to our climate, and I can't think
of any indigenous species of tree which doesn't mind its feet in salt
(or even brackish) water.
