And, I quite sympathise with the (tourist) passengers wanting to take pictures but being hampered by the acoustic barriers... those are going up all over around here, too... :) BM>> Unfortunately the water is rather dirty, especially during a flood.

That could be interesting as long as the water isn't too murky.... :) NB>>> Definitely things that need to be considered... not a simple problem... BM>> No, not at all simple. Lots of variables like elevation and usages (a BM>> low-lying park could be allowed to flood, low-lying access to a bridge BM>> probably not).
