Dataset accompanying the publication "Transport and retention of micro-Polystyrene in coarse riverbed sediments: Effects of flow velocity, particle and sediment sizes"
Summary
This dataset accompanies a study on how flow velocity, particle size, and sediment grain size affect the transport and retention of polystyrene microplastics in riverbeds. The raw image files support research into how microplastics move through freshwater systems and accumulate in sediment.
The dataset in this repository is accompanying the publication "Transport and retention of micro-Polystyrene in coarse riverbed sediments: Effects of flow velocity, particle and sediment sizes" (in Microplastics and Nanoplastics, 2023, submitted 09.06.2023) by Matthias Munz 1, Constantin Loui 1, Denise Postler 1, Marco Pittroff 2,1, Sascha E.

In addition, we provide the resulting data from the particle identification and geometric analysis which were derived from the raw data using ImageJ in tabular excel format. The data is structured in folders following the naming of the columns from the manuscript.

This is an additional data repository accompanying the same study on microplastic transport in riverbed sediments. The data is provided to support reproducibility and further analysis of microplastic fate in freshwater environments.
Transport and retention of micro-polystyrene in coarse riverbed sediments: effects of flow velocity, particle and sediment sizes
Researchers conducted column experiments to investigate how polystyrene microplastic fragments are transported and retained in coarse riverbed sediments under different flow conditions. They found that most particles were captured in the upper 15-20 centimeters of sediment, but smaller fragments between 100-500 micrometers could penetrate to depths of at least 50 centimeters. The study suggests that riverbeds can act as both temporary sinks and long-term retention sites for microplastics, slowing their transport from streams to oceans.
The effects of large roughness elements on the in-stream transport and retention of polystyrene microplastics
Laboratory flume experiments showed that large roughness elements like boulders in riverbeds significantly alter how polystyrene microplastics are transported and retained, with two distinct flow regimes determining whether particles travel quickly or get trapped. Understanding these river dynamics is essential for predicting where microplastics accumulate in freshwater systems and designing realistic environmental risk models.
Data and code for the publication "Assessing the Behavior of Microplastics in Fluvial Systems: Infiltration and Retention Dynamics in Streambed Sediments" - Part 1(2)
This dataset supports research on how microplastics move through streambed sediments in experimental flume conditions, measuring infiltration and retention dynamics. Understanding microplastic trapping in riverbeds is important for predicting their long-term fate in freshwater ecosystems.
