I argue that under normal conditions the velocity in the shallow flood plain is zero and during a flood it is non-zero. :)

Seriously though, in normal conditions there isn't much water in the normal river bed that is standing fairly still, although of course there is some.
In flood conditions, in broad flood plains, there may be a vast expanse of water that is barely moving.
