Scour associated with anthropogenic activities in the marine environment has exercised the minds of scientists and engineers for decades. Despite the advances in understanding there remain areas of uncertainty which require further examination and challenges that require further research. Whilst real-life scour problems often help formulate the questions for detailed laboratory experiments, the associated information is less often used to answer some of those questions and yet the available data can offer the chance of exploring the scour at full-scale using real marine soils, albeit with all the inherent uncertainty associated with measurements obtained in the field. It can be argued that through the interpretation of these data, it forces the scientist and engineer to not only explore in more detail the limitations of the measurements but to engage in the full range of processes, whether physical (e.g. hydrodynamics and meteorological forcing) or biological (e.g. marine growth, benthic organisms) that impact on structures placed in what are often, very challenging environments.

“…Scour tests were conducted in two laboratory flumes of different dimensions. Details of the experiment set-up and test program can be found in Porter et al (2012) and Porter et al (2014). A range of hydrodynamic conditions (currents, waves, tidal flow) and several pile diameters were used in the test program which presented some restrictions in terms of the set-up of the measurement system.…”

Laboratory studies form an integral part of scour research, yet there is no standard technique for monitoring scour depth development during testing. This paper investigates the advantages and disadvantages of a variety of techniques, and compares results from three methods: photogrammetry, an echosounder, and a calibrated pile. A novel system involving an underwater camera is presented. This produces results in close agreement with the other techniques, and has the advantage of providing accurate measurements over the full scour hole while at the same time enabling qualitative information to be gained from the photographs.

“…In-N t Outer N t Scour development under tidal currents has been studied by Ecarameia &May (1999), andJensen (2006), and more recently McGovern et al (2014) and Porter et al (2015) but these studies focused on the variation of tidal current only.…”
