water). From the velocity field it is possible to determine different variables such as shear stresses, identify recirculation
regions, among others. The development of optical techniques allowed for measurement techniques based on image
acquisition and processing, namely PIV (particle image velocimetry) and PTV (particle tracking velocimetry). In this paper
an algorithm combining both PIV and PTV techniques is presented, allowing in this way to profit from each technique
strong points and allowing the simultaneous measurement of the water and sediment layer velocity fields and to obtain a
better know how of the fluid-sediment interaction. The advantages and limitations of the proposed techniques are explored
and debated by means of a laboratory experiment.
The Centre for Territory, Environment and Construction (CTAC) is a research unit of the School of Engineering of University of Minho (UMinho), recognised by the “FCT – Fundação para a Ciência e Tecnologia” (Foundation for Science and Technology), associated to the Department of Civil Engineering (DEC), with whom it shares resources and namely human resources.
Currently CTAC aggregates 25 researchers holding a PhD of which 20 are faculty professors of the Civil Engineering Department. Read more
