Oscillation Ripples
Oscillation wave ripples provided by Nikki Strong, St. Anthony Falls Hydraulic Laboratory & Department of Geology and Geophysics, University of Minnesota.

Shows the development of wave ripples with regular spacing in a small (15 cm wide x 46 cm high) flume. Quartz and coal sand are used. First view, from above, has a wave period of ~1 second. Ripples develop straight crests (i.e. 2-D ripples) that die out towards the lower part of the frame where the sediment
surface is deeper (below wave base, see sketch below). The ripple wavelength is about 2 cm. The second view is from the side with a wave period of about 0.7 second.
