Suspended sediment dynamics over a dune in the Rio Paraná

Publication Date

Book Chapter


This study examines turbulence and sediment suspension over large sand dunes in the Río Paraná.. An acoustic Doppler current profiler was used to measure three-dimensional velocity, and at-a-point suspended sediment concentration and particle-size were measured with a laser in situ scattering transmis-someter. Phase coherence wavelet analysis of time series indicates that fluid ejections sourced near the bed suspend sand into the overlying flow.
