Flow velocity measurements over a migrating train of dunes in a flume in the laboratory

<p>Acoustic Doppler Velocimeter (ADV) measurements conducted over a migrating train of dunes in a flume in the laboratory. The files with an .ntk extension are the raw data as measured and recorded by the instrument (Nortek Vectrino Profiler) and those with an extension .mat are the raw data as exported from the original software into a MatLab readable file format.&nbsp;<br> The data was used to create a streamwise flow velocity profile in the publication associated with this dataset.&nbsp;<br> File names have a nominal distance to the bed in mm expressed by the numbers at the end of the name. For example, 00_10 indicates measurements from 0 to 10 mm. However, as the measurements were conducted over a migrating train of dunes, those numbers are not as precise. However, the instrument records the distance to the bed and it is available inside the files. The distance inside the files is the one used to create the figure for the publication.&nbsp;<br> <br> In the upcoming publication the data was used to plot figure 4(d)<br> <br> The figure is available as 4D&nbsp;in the preprint found in this link:&nbsp;https://www.researchsquare.com/article/rs-1370465/v1</p> <p>&nbsp;</p>
