Ripple Vortex entrainment study

Within the European project Hydralab III- SANDS (http://www.hydralab.eu/), measurements of the flow, suspended sediments and ripple shape were collected under regular waves above a sandy bed in a large scale flume facility (UPC-CIEM, Spain). The objective of the study was to obtain simultaneous collocated near bed profiles of the horizontal and vertical flow and the suspended concentration, as bed forms changed due to increasing wave height. To obtain the measurements a recently developed dual frequency ACVP was deployed to provide concurrent measurements of the hydrodynamics, the entrained sediments and the location of the bed.
