Actually Germany and Netherlands experienced massive floods this year with increased river volumes in the Maas due to excess rain and ice melt in the Alps. At least 200 people died, 10s of thousands relocated.
My point is not all your flood threats are downstream from you.

The dutch have centuries of know how and an entirely separate body to oversee all water management the Rijkswaterstaat. To assume that their model can be easily copied is a massive underestimation of the problem/solutions.
- phicoh 5y agoThere is an interesting thing related to the recent floods that happened in Begium, Germany and The Netherlands. The Netherlands spends quite a bit of effort estimating flood risks, and for more important water defenses tries to get the chance of disaster down to about one in 10000 years. However, it seems that this calculation is only done for the lower parts of the country. The Meuse was only taken seriously after a couple of floods in the 1990s (and works were just far enough in The Netherlands that places along the Meuse were mostly fine). However, for smaller rivers, nobody seems to care.
