washboarding
thumb|Washboarding effect on a road
Washboarding or corrugations is the formation of periodic, transverse ripples in the surface of gravel and dirt roads. Washboarding occurs in dry, granular road material with repeated traffic, traveling at speeds above . Washboarding creates an uncomfortable ride for the occupants of traversing vehicles and hazardous driving conditions for vehicles that travel too fast to maintain traction and control.
Turing pattern
how patterns in nature, such as stripes and spots, can arise naturally and autonomously from a homogeneous, uniform state
pattern formation
study of how patterns form by self-organization in nature
