Problem with that is that Main Donau Kanal has like 30 sluices and takes several days to traverse. Also, EU is investing in transport corridors from Scandinavia to the south, going down the Rhine is a major detour in that case. Trains of course are faster, but water transport is quite cheap and has high volumes, as Im sure you know. Investing in canals and sluices in the other rivers in Europe will be necessary anyway in the next decades to manage water levels throughout the year. As the current flooding along Rhine and Donau shows, there needs to be both capacity to increase water flow in times of heavy rainfall, beyond what is currently possible, and to retain water during droughts, that can be used to irrigate the land and prevent crop failure. The reason we can manage water levels in the Netherlands in these circumstances is because we invested in building this infrastructure, and thus, our rivers are traversable in all but the driest summers, and nobody's house gets flooded except in extreme rainfall, much worse than what we are getting currently. Greetings from Holland :)

To manage droughts you will need to build water infrastructure anyway. If you dont build anything because it would harm the nature reserves, they will dry out and die regardless. Connecting rivers and lakes to be able to transfer water t areas where it is needed, and to be able to dissipate water during extreme rainfall like we are having currently, will be essential in the near future as dry and wet seasons will get worse due to climate change.

@wensdyy6466 if you restore the wetlands you will still need to improve in drainage, aka canals with sluices, for the extreme rainfalls that will also result from climate change in the spring and fall seasons, as well as meltwater that isnt being retained by glaciers. otherwise your wetlands will turn into lakes and overflow for half the year, which also results in loss of biodiversity.

@wensdyy6466 the problem is that if you dont maintain the water level in the wetlands, and it gets too high, a lot of plants, amphibians and birds that rely on undeep wetlands wont be able to live there.

@wensdyy6466 climate change is also impacting wetlands that are untouched, because it creates more extreme dry and wet seasons that the local biome is not capable of dealing with naturally. because these circumstances didnt occur before climate change. at least not frequently.

@wensdyy6466 oh and as for your previous argument about evaporation in the waterways. the romans already solved that two thousand years ago by putting a lid on their aqueducts.
