The formation and migration of sand ripples in closed conduits: Experiments with turbulent water flows
Abstract
We investigate the formation and migration of sand ripples in closed conduits. Turbulent water flows were imposed over a granular bed in a transparent channel. The growth and migration of ripples were filmed by a high-definition camera. The length and celerity of ripples were determined by post-processing the images.
