On a river cruise starting Oct 21. Seems like the various rivers in Europe like Rhine and Danube are too low for cruise boats. Any current experiences?
Perhaps a better resource for your question would be on the Facebook sites for each of the river cruise lines, or on the river cruise forum on Cruise Critic. Or on your specific river cruiseline website.
No personal recent experience, but I have to wonder, if the river’s too low, does the river cruise become a bus tour - with lots of buses?
Some tours get cancelled, some become bus / boat where river levels are still viable. It depends on the cruise line.

Not my personal experience, but a friend of mine was supposed to start a Danube cruise with Grand Circle on Oct. 15 and they (the cruise line) cancelled it. She rebooked for next year.
This is a link to the newest page (at the moment) of a thread on Cruise Critic's forums that has been tracking the Danube river levels all year. (It's up to 55 pages.) I don't understand a lot of what they are talking about, but you can get a sense of how things are going. Or not going...

No personal experience, heard lots from those who have had issues, on here, other forums, and personally.
The Danube is still having issues (as is the Rhine), but in both cases, only sections of the river. For the Danube, you can't get above Passau, and Vienna to Budapest is still having issues.
Two weeks from now? You are asking a lot to improve.
What happens? That is up to the cruise company, may be dependent on how large their boats are, the draft, and what sections they can navigate. The most common solution is that they will cruise sections they can, if they have boats available in those sections. Between areas, yeah, you bus, maybe you use a hotel, maybe they have a boat docked to use. They really do try to duplicate the itinerary in most cases, even using small excursion boats to day-cruise through scenic areas, but sometimes they get creative.
Some companies on the Rhine have gotten creative, rather than doing a bus tour, they have taken to cruising from Amsterdam to areas in the Netherlands, Northern Germany, and Belgium, changing it up entirely. I don't think cruises on the Danube have that same flexibility.
It does sound however, that the cruise companies this year are offering more compensation than in the past, better cancellation options, even though their terms of service clearly state the risk of low water levels.
You might try the Cruise Critic Forum for some recent experiences versus here.
