ClearTransport processes of microplastic particles in the fluvial environment : erosion, transport and deposition
This thesis examines how microplastics are eroded, transported, and deposited in river systems, tracing their movement from land sources to the ocean. The research fills an important gap in understanding how rivers act as conduits for microplastic pollution and what processes determine where plastic particles accumulate in freshwater environments.
The Effect of Sediment Texture on the Composition and Abundance of Microplastics in Banjaran River, Banyumas Regency, Indonesia
Researchers examined how sediment texture influences the composition and abundance of microplastics in the Banjaran River in Banyumas Regency, Indonesia, finding links between particle size distribution in sediments and microplastic accumulation patterns.
A numerical model of microplastic erosion, transport, and deposition for fluvial systems
Researchers developed a numerical model of microplastic erosion, transport, and deposition in river systems, finding that rivers act as temporary sinks trapping significant fractions of MPs before they reach the ocean, with implications for estimating marine MP loading from terrestrial sources.
Relative contributions of different local sources to riverborne microplastic in a mixed landuse area within a tropical catchment
Researchers quantified the relative contributions of different land-use sources to riverborne microplastics in a tropical catchment, providing data to help prioritize pollution reduction measures for protecting human and ecological health.
The influence of weirs on microplastic fate in the riverine environment (case study: Jeneberang River, Makassar City, Indonesia)
Researchers studied how weirs — structures built across rivers to control water flow — affect microplastic transport and accumulation in the Jeneberang River in Makassar, Indonesia. The findings show that weirs cause microplastics to accumulate upstream rather than reaching the ocean, revealing how river infrastructure shapes microplastic fate.
The abundance of microplastics in Siak tributary sediments in the watershed area, Pekanbaru City, Riau (Case Study Sago River)
This study quantified microplastics in sediments of the Sago River, a tributary of the Siak River in Indonesia, finding elevated concentrations linked to dense human activities in the catchment. The results highlight tributaries as important entry points for microplastics into larger river systems.
Understanding the spatio-temporal behaviour of riverine plastic transport and its significance for flux determination: insights from direct measurements in the Austrian Danube River
This study analyzed the spatio-temporal behavior of plastic transport in rivers, examining how flow conditions, catchment characteristics, and seasonal variation influence plastic flux and retention within river systems.
The Abundance of Microplastics in Sediment Siak River Pekanbaru City
Researchers assessed microplastic abundance in sediments of the Siak River, Pekanbaru City, examining the river as a pathway for land-based plastic waste to accumulate in aquatic sediment reservoirs given high water utilization activity along its banks.
Assessment of Sediment Grain Size and Its Correlation with Microplastic Accumulation and Characteristics in the Kahayan River, Indonesia
Researchers investigated microplastic accumulation in sediments of the Kahayan River in Indonesia in relation to sediment grain size, finding an average abundance of 7.3 items/kg dry weight. Significant correlations were found between coarse and fine sand grain sizes and microplastic occurrence, suggesting grain size plays a key role in microplastic retention.
Direkte Mikro- und Makroplastiktransportmessungen an großen und mittleren Flüssen sowie im Ablauf von Kläranlagen
This German-language study presents direct measurements of micro- and macroplastic transport in large and medium-sized rivers as well as wastewater treatment plant effluents. It addresses a research gap in freshwater plastic transport quantification, providing empirical data on how rivers carry plastics toward marine environments.
Spatial distribution of microplastic in sediment of the Citanduy River, West Java, Indonesia
This study mapped the spatial distribution of microplastics in sediments along the Citanduy River in West Java, Indonesia, finding widespread contamination that varied by location and land use. Rivers like the Citanduy act as conveyor belts carrying microplastics from inland areas to coastal and marine environments.
Leveraging Sedimentary Process Insights to Enhance Understanding of Microplastic Deposition in Rivers
This review leverages insights from fluvial sediment transport research to improve understanding of how microplastics deposit and are buried in river networks, identifying knowledge gaps in water-sediment exchange processes and highlighting that current MP deposition estimates are biased by incomplete understanding of flow-sediment-particle interactions.
Phenomenological model of suspended sediment transport in a small catchment
This paper is not relevant to microplastics; it presents a hydrological model for suspended sediment transport in a small tropical river catchment in Guadeloupe.
Model-based analysis of erosion-induced microplastic delivery from arable land to the stream network of a mesoscale catchment
Researchers developed the first catchment-scale model estimating how much microplastic is transported from farmland soils into stream networks through soil erosion. The study found that erosion can be a significant pathway for moving microplastics from agricultural fields into rivers, with implications for downstream water quality.
Sinks and sources: Assessing microplastic abundance in river sediment and deposit feeders in an Austral temperate urban river system
Researchers investigated microplastic abundance in river sediments and depositional zones, finding that sediment acts as both a sink and a temporary source, with stored microplastics re-mobilized during high-flow events.
Spatio and temporal dynamics of microplastic fluxes within the watercourses of a peri-urban watershed
Researchers tracked the spatiotemporal dynamics of microplastic fluxes within a river catchment over time, linking plastic transport patterns to land use activities. The study found that land use type is a key driver of when and how much microplastic enters and moves through watercourses.
Quantification, characterization, and source identification of macro- and mesoplastics in the water column of Rivers Sabaki and Tana.
Researchers sampled plastic litter in the water columns of two Kenyan rivers over a full year, quantifying plastic loads and tracing their sources using statistical analysis. The findings establish baseline data on riverine plastic flux to the Indian Ocean from East Africa and showed that rainfall significantly influenced plastic transport.
Longitudinal and Vertical Transport of Microplastic Within Sediment in Rivers and Transitional Water Environments
Researchers investigated the longitudinal and vertical transport of microplastics within sediments in rivers and transitional water environments, developing models to quantify how sediment presence affects microplastic mobility and their transport toward coastal areas.
Quantification Of Macroplastics Under Differing Weather Conditions Near A Japanese Farmland River
Researchers quantified macroplastic (>5 cm) accumulation under different weather conditions near a farmland river in Japan, finding that rainy-day collection rates (~1.39 samples/hour/m2) nearly doubled those of sunny days (~0.87 samples/hour/m2). The study demonstrates that rainfall is a key driver of macroplastic mobilisation and transport in agricultural river systems.
Transport dynamics of microplastics from land to sea: the role of particle properties and stream morphology.
Researchers measured how particle properties including size, density, and polymer type interact with stream morphology to determine microplastic transport distances in 15 streams.

The influence of flow on the amount, retention and loss of plastic pollution in an urban river
Researchers sampled both microplastics and macroplastics at four sites along an urban river in Ontario, Canada during normal flow and storm conditions. The study found that storm events significantly influence plastic transport dynamics, with flow conditions affecting how much plastic pollution is retained in or flushed through urban river systems toward downstream water bodies.
