Abstract

<p>Three-dimensional sedimentary structures occur frequently in coastal and river environments, and a common dynamics is possibly responsible for them. Brick-pattern ripples show a regular three-dimensional configuration composed of transverse crests and longitudinal bridges between the crests. Various studies have been made to examine the formation mechanism of brick-pattern ripples. However, they are insufficient to explain how the brick pattern appears on the surface of sand in an oscillatory flow. In this study, we make experimentally the detailed observation of the formation process by means of visualization and SfM-based 3D modeling to verify the brick-pattern ripple formation mechanism.</p>
