Washboarding effect on a road. Washboarding or corrugation [1] is the formation of periodic, transverse ripples in the surface of gravel and dirt roads.Washboarding occurs in dry, granular road material [2] with repeated traffic, traveling at speeds above 8.0 kilometres per hour (5 mph). [3]
A hot-road mirage, in which "fake water" appears on the road, is the most commonly observed instance of an inferior mirage. Heat haze seen through exhaust gas from a jet engine Heat haze , also called heat shimmer , refers to the inferior mirage observed when viewing objects through a mass of heated air.
A road running below the water level of a stream or river is often known as a "watersplash". It is a common name for a ford or stretch of wet road in some areas, and is sometimes also used to describe tidal crossings. They have become a common feature in rallying courses. Some enthusiasts seek out and drive through these water features ...
Capillary waves (ripples) in water Ripples on Lifjord in Øksnes Municipality, Norway Capillary waves produced by droplet impacts on the interface between water and air.. A capillary wave is a wave traveling along the phase boundary of a fluid, whose dynamics and phase velocity are dominated by the effects of surface tension.
Sun glitter is a bright, sparkling light formed when sunlight reflects from water waves. The waves may be caused by natural movement of the water, or by the movement of birds or animals in the water. Even a ripple from a thrown rock will create a momentary glitter. Light reflects from smooth surfaces by specular reflection.
The forecaster explains: “When air blows across a mountain range, in certain circumstances, it can set up a train of large standing waves in the air downstream, rather like ripples forming in a ...
Breaking waves cross a sand bar off the shore. The pushed-in water can most easily travel back out to sea through a gap in the sand bar. This flow creates a fast-moving rip current. A rip current (or just rip) is a specific type of water current that can occur near
A diagram of an aquaplaning tire Two vehicles aquaplaning through large puddles on the road's surface. Aquaplaning or hydroplaning by the tires of a road vehicle, aircraft or other wheeled vehicle occurs when a layer of water builds between the wheels of the vehicle and the road surface, leading to a loss of traction that prevents the vehicle from responding to control inputs.
