If you want to do that, that means you probably don't need a River but something similar to a batch I guess.
To answer to your question, I think that it first depends on the river implementation itself. In most cases, remove the river and create it again.
It should do the trick.

Can I run a River "on demand" or do I have to wait for it's polling time to expire?
