Abstract

This study investigates the formation and planar shape of barchan ripples generated by laboratory unidirectional water currents and compares the morphology with that of barchans formed by laboratory waves and flows in natural environments. A thin veneer of sand as a sediment source was placed initially at the upstream part of a recirculating flume and the change in bed configurations by the flow was recorded by a video camera. Two types of formative process were observed : one was that barchan ripples grew from barchanoid bedforms and the other was that they developed from a small aggregate of sand particles
