form a sand bank into the channel. With respect to the relation between the motion
of particles and vortices we can assert the following: the dipole and the spanwise
vortices are structures that enhance the particle transport. Particles are sucked in the
region between vortices and are expelled forward. It is important to note that the
accumulation of particles coincides with the region where the dipole moves. Finally,
the experimental observations are consistent with numerical (López-Sánchez and
Ruiz-Chavarría 2013a ) and observational (Amoroso and Gagliardini 2010 ;deSwart
and Zimmerman 2009 ) results reported in the literature.
