Floating logs of wood tend to move to thy' mid-river reach on the water surface. This is due to

Fastest velocity along the mid-river reach

Least obstruction from the banks

2-cell transverse circulation in the flow

Near-symmetry of the isovels across the section is conducive to principle of least work
