A loopable beautiful relaxation video of patterns of the waves spilling over the sand ripples. I liked the imagery. There is the calming sound of the waves and the lovely happy sound of children playing very faintly in the background. It was a beautiful sunny clear blue sky day in October 2015 on Putsborough Beach, Woolacombe Bay, North Devon, England, UK. I didn't have my normal high standard of video equipment with me but luckily I got a mobile phone with a high quality camera set, a Lumia 930 and it worked quite well. It has been edited on Sony Vegas platinum. Filmed by Steve Shelton.

Urchin says: This is for the sedimentology geologists! This was taken on a beach in Oregon. Antidunes were forming in a small stream. When wavesinterfered with the stream flow, stream energy decreased and the antidunes disappeared. For those of you who are not sedimentary geologists (people who study the science of sand, gravel, lime mud etc. transport, deposition, and rock formation), antidunes form when the stream water flows at a very high velocity -- very fast -- and the stream erodes the sand in front of the small dune or ripple beneath the water surface and "eddies" some of the sand back upstream. This constant erosion in front of the dune and eddying of some of the sand back upstream forms a dune that moves backwards, or upstream against the flow of the water, rather than downstream, like normal ripples or dunes. Often, in shallow streams like this one, the surface of the water over the antidune is seen to ripple or swell over the antidune, and those water ripples move upstream with the antidunes. When the waves moved onto the beach and the ocean water ran up the stream, the downstream flow of the small stream slowed when the wave water and stream water met; the stream flow velocity decreased (became slower) and was too slow to form antidunes. When the wave receded off of the beach, the stream was no longer being interfered by wave action, and the stream flowed fast enough to form antidunes again. Watch two cycles of antidune formation - wave interference with flow in this video.

Close-up demo of sand transport in a small-scale transportable circular flume. Illustrates a plethora of sedimentary processes and structures: Collapse of laminar boundary layer, formation and migration of ripples, traction carpet, turbulent flow, flow separation at dune crest, helical flow, sweep-and-burst mechanism etc.

In this oil painting tutorial I'll show you how to paint sand dunes in a beach scene. You'll see me demonstrate my technique for making the sand dunes look photorealistic with oil paints. I'm a professional landscape artist with over 20 years of experience in oil painting. My YouTube Channel is dedicated to helping people learn how to paint in oils. I really believe that everyone can learn how to paint!

This 360-degree panorama was acquired by the Mast Camera (Mastcam) on NASA's Curiosity rover looking out over part of an area called Bagnold Dunes, which stretch for miles on Mars. This location, called "Ogunquit Beach," is on the northwestern flank of lower Mount Sharp. Points of interest include the dune’s ripples, and bedrock made from sediments deposited in lakes billions of years ago. From February to April 2017, Curiosity examined linear sand dunes to compare with what it found in 2015 and 2016 during an investigation of crescent-shaped dunes. This two-phase campaign is the first close-up study of active dunes anywhere other than Earth. This panorama was stitched together from 115 individual images acquired on March 24-25, 2017, (PST) during the 1,647th Martian day, or sol, of Curiosity's work on Mars. The rover's position on Sol 1647 is shown at https://mars.nasa.gov/multimedia/images/2017/curiositys-traverse-map-through-sol-1646 as the location reached by a drive on Sol 1646. The scene is presented with a color adjustment that approximates white balancing, to resemble how the rocks and sand would appear under daytime lighting conditions on Earth.

Huntington Beach, CA - 5/14/2015 Rain water run-off from a beach storm drain, between lifeguard towers 12 and 14, on the north side of the pier, creates a fast, moving stream to the ocean; where you can observe "sand waves" moving up stream. These moving waves are also called "antidunes".
