Current and Wave Ripples. Ripple marks are present as undulations on a non- cohesive surface, though they may also be found infrequently in muddy sediments as well. They are produced as a result of the interaction of waves or currents on a sediment surface. Ripple marks are one of the commonest features of 5 Jul 2016 The bedforms, or ripples, that run horizontally down the face of sand dunes are caused by wind-borne sand grains colliding with surface sand. These "impact ripples" are found only on the windward side of the dune, and not on the leeward face, which is typically steeper due to sand avalanches.
