I have a question that's been puzzling me for many years now.
I'm supposed to be a person of average intellect and so on, but this is obviously not the case.
Reading todays issue of the "Sunday Times", I read that a new Thames Barrier will be required to prevent London being flooded by a combination of London "sinking" and rising sea levels. So far, so good.
Now, if I have a stream of water coming into my garden and build a "barrier", the water seems to have the nonce just to flow around the ends of my barrier making my efforts redundant.
So. Spend squillions of £ building a new barrier closer to the sea, where the estuary is both wider and "flatter" at its shores is a good idea? Why can't all this expected and hypothetical water just come around the sides?
Other rivers in this realm seem to meander around in a reasonably benign manner without needing a door shut in its face.
Basically, what it boils down to is that I just don't understand why water stops and says to itself " hello, there's a door here, better find somewhere else", rather than just saying "oh, 'xxx' it, I'm going around it anyway".
Or am I just as thick as the water? BY.
