The Takeaway

While we know the Coriolis force affects hurricanes, this study proves it is powerful enough to determine exactly where a river's sediment ends up. In certain sections of the Yellow River, the planet's spin acts like a ghost hand, constantly pressing the water and its debris against the right bank.

From the abstract

In the northern hemisphere, river subjects the right bank to the pressure generated by the Coriolis force, which will increase the erosion of the river on the right bank. On the other hand, the Coriolis force also causes the sediments in the water to move to the right bank, which will increase the sediment deposition on the right bank of the river. Therefore, for rivers with low sediment content, Coriolis force will increase the erosion of river water on the right bank; for rivers with high sedi
