The science of washboard roads

Up in the area where we vacation, a couple of dirt roads form part of the boundaries of the property. Last time we were there, I commented on the "washboard road" and we had some discussion about what makes the washboarding appear. Now, a couple of scientists have a theory, which can be found at Road Bumps: Why dirt roads develop a washboard surface.
