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.
Linguoid ripples generate an angle to the flow as well as downstream. Linguoid ripples have a random shape rather than a "W" shape, as described in the catenary description. Lunate ripples, meaning crescent shaped ripples, are exactly like linguoid ripples except that the stoss sides are curved rather than the lee slope. All other features are ...
A rip current forms because wind and breaking waves push surface water towards the land. This causes a slight rise in the water level along the shore. This excess water will tend to flow back to the open water via the route of least resistance.
Giant current ripples usually exhibit antidune breaking wave and dune ripple shapes, resulting from their high energy environments. Giant current ripples can reach a maximum height of 20 metres (66 ft) and reach a maximum length of 1 kilometre (0.62 mi). they occur in ripple fields that can cover an area several kilometers across.

Symmetrical ripple. Although symmetrical ripples are also called bi-directional ripples there is a difference between them. Bi-directional ripples are rarely symmetrical due to the difference in force of the two directions, where as the wave formed or oscillation ripples form from the circular water movement pattern of water molecules.
Researchers have warned that human impact on the ocean is putting increasing pressure on dolphins and whales, and their ecosystems. The UK whale and dolphin conservation charity Orca recorded ...

A rip current is a strong, narrow jet of water that moves away from the beach and into the ocean as a result of local wave motion. Rip currents can flow quickly, are unpredictable, and come about from what happens to waves as they interact with the shape of the sea bed.
