Field data from the Rio Paraná, Argentina, are used to examine patterns of suspended sediment transport over a sand dune. Measurements of three-dimensional velocity are made with an acoustic Doppler current profiler whilst suspended sediment concentration and particle size have been quantified using a laser in situ sediment scattering transmissometer. The field measurements and model predictions both indicate that deposition of sand travelling in suspension close to the bed contributes to dune migration and may impart considerable control on the lee side slope angle
