TLS data show the bed surface topography before and after waterworking of the bed. CT scan data show the 3D structure of sections of the river bed after waterworking. Some CT data has been processed to segment the images into the individual gravel grains, and for some of these data a database of grain properties is also available.

The bed was scanned using TLS. Flow was run through the flume to waterwork the gravel, and then the flume was drained. The bed was rescanned using TLS. Then the baskets were extracted, and CT scanned. 15 experimental runs were completed, with increasing amounts of sand and clay added to the flume throughout the experiment. CT data were processed to remove any scan artefacts, and to segment the gravel grains from the surrounding matrix and other materials. These segmented scans were then analysed to measure grain properties.
