NC & VA Rivers

Recommended Posts

scubapro67

Can anyone explain why the majority of rivers in NE NC and SE VA have most of their high banks/ bluffs on the southern (right) sides?  And please let me know if I have that wrong and they're not skewed that way.....but it does seem like that.

Thanks.

It has been known for a long time that rivers in the Northern Hemisphere  have steep banks on the right side and rivers in the Southern Hemisphere have steep banks on the left side. The usual explanation is this results from the coriolis effect but not everyone agrees with this explanation.

Thanks - Should probably of known that.

The Coriolis effect on river bank erosion is attributed to Karl Ernst von Baer (Baer's Law). 

Einstein later noted that as a river flows to the bend in the Earth's surface the Coriolis Effect adds rotation and corkscrewing as the water flows downstream.  In the northern hemisphere, this water flow drags on the river bed then moves slowly to the left side, gaining speed as it rises to the surface and travels to the right side scouring the banks and sinking again.
