And sometimes it has unexpected consequences. We have retention dams upstream of a local river, for the purpose of absorbing sudden heavy flows and releasing them later at a lower rate (damping the system). There have been occasions, however, where the heavy flows were successive and filled the dams, so that the dams had to release water at a rate that indeed caused some flooding. It was either that, or the dams would overflow and possibly collapse.
The point being that "geoengineering" entails these projects, and they are commonly accepted on the basis of experience that they are helpful and necessary. I don't see any difference with cloud-seeding, as the available data indicates they augment natural rainfall by about only 24%
Funny you mention "flood control"
