However, studying the scour time evolution is critical to better understand the erosion process and the main factors that control it in the short and long terms. Scour is a destructive process, therefore, in the absence of non-intrusive and real-time measurement techniques, an experimental analysis of time evolution of scour can be a time-consuming process as, for each considered instant, detailed measurements of the bed geometry must be taken. In this paper, two different strategies

are applied to analyse the scour time evolution. Their results are compared and discussed. From the obtained experimental results, empirical relations between different variables were proposed. Further analysis provided scale relationships to adimensionalize the time evolution profiles. To measure the scour geometry, a structure from motion technique is employed.
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
