Protective dam

Ybl Miklós he built it next to his friend's house, but the neighbors also followed his example. The dam will be needed now! The Danube is flooding!
Maybe the translation is not good! Sorry!

A very substantial wall....hope it will keep any water out.

I have been following the floods in Europe, I certainly wish and hope that is wall is high enough.

[Lesley Aldridge]

I hope it keeps the water out, these weather events seem to be happening more and more often.

[Rob Z]

It looks like it might be a really good idea if that lower level goes under water...

Who is laughing now?!
