A plan to build a barrage across the wash-

As ridiculous ideas go this is daft-

the Wash is an internationally important wetland- it's theoretically protected by international law ( although now we've left the EU they could probably get around that )

-and someone wants to build a giant dam with turbines etc. from Gibraltar Point to Hunstanton:

I wonder if it will cause the whole of the North Norfolk coast to flood - or push tidal flow around into the Thames basin and swamp the Thames barrier?
