Data obtained from experiments on the sediment transport and morphodynamics induced by a translating monopolar vortex. The volume occupied by the suspended sediment was dynamically measured using a vertically moving horizontal laser sheet which illuminated cross-sections of the region where particles were suspended. Changes in the particle bed were measured using a single camera photogrammetric technique. The vortex characteristics (size, strength, trajectory and velocity) where obtained using Particle Image Velocimetry (PIV). Two types of particles were used. The first type of particles (referred to as PS particles) were translucent, spherical, polystyrene particles with an average diameter 580 μm and a density equat to g/cm^3. The second type of particles (referred to as PMMA particles) were smaller and heavier, with a diameter between 250 μm and 300 μm and a density equal to 1.20 g/cm^3. Experiments without a sediment bed were also performed and compared to their counterparts with sediment to determine possible effects of the changes in the sediment bed and particle loading on the vortex.
