Garcia, Marcelo H. Pedocchi Miljan, Francisco 2015-09-25T21:04:44Z 2015-09-25T21:04:44Z 10000-01-01 2009 2009 The experiments focused on two aspects of the bed morphology: the study of the ripple planform geometry under a broad range of flow conditions, and the effect of orbital velocities on the ripple size under long water excursions. Regarding the planform geometry of the ripples, the results showed that narrow facilities restrict the three-dimensional development of bedforms. For the case of the long water excursion experiments, the ripple size was found to initially decrease as the maximum orbital velocity was increased, as it has been reported by other authors. However, as the maximum orbital velocity was further increased anorbital ripples did not develop and instead the ripples started to increase their size. These last ripples had round crests, and do not seem to belong to the same bedform class as the sharp crested ripples usually reported in the literature.
