Replication dataset for “Migrating subaqueous dunes capture clay flocs”
This is the data underlying the publication “Migrating subaqueous dunes capture clay flocs”. It consists of the data as described in the publication, being the floc characteristis from the floc cam, grainsize distributions, bed profiles from the StreamPro, Kolmogorov calculations, the GoPro images from the experiments, and the lab sheet of the experiments. For more information I refer to the read-me file. The abstract of the research in which this data is used reads: "Recent research highlights the abundance of floccule (flocs) in rivers, formed by the aggregation of clay particles with organic matter. These flocs affect the transport and eventual fate of clay. Flocs exhibit distinct behaviour from their unflocculated sedimentary counterparts: they can deform and break, and have higher settling velocities, which may in turn cause flocs to have the potential to deposit and possibly interact with the riverbed. Systematic experiments in a laboratory flume were conducted. Flocs showed a saltating (bouncing) behaviour, and were incorporated in the sediment bed as single flocs, clusters, or strings, via deposition and burial in the lee of a dune. The dune geometry was negligibly impacted by the presence of flocs. This study is the first to highlight interactions between flocs and bedforms. In natural systems, the burial of flocculated clay particles can affect contaminant spreading, aquatic ecology, the interpretation of deposition patterns, and clay transport."
