From Riverine Transport to Legal Evidence: Coupled Hydrodynamic–Ecological Modelling of Transboundary Plastic Pollution
AI summary Read the abstract
This study builds a computer model combining water flow and ecological data to track plastic pollution in rivers that cross national borders. The goal is to identify where the plastic pollution comes from and how it spreads, information that could serve as evidence in disputes between countries.
Transboundary rivers transport plastic pollution across political boundaries, yet the evidence base available for characterizing this movement remains dominated by concentration measurements that cannot resolve where contamination originates or how it is redistributed. This study develops and ...

Modelling Microplastic Transport in River Systems Using the SWAT Hydrological Model
AI summary Read the abstract
Researchers developed a novel modelling approach using the SWAT hydrological model to simulate microplastic transport through river basin systems, integrating hydrological and physical plastic properties. The model provides a tool for understanding the spatial and temporal dynamics of freshwater microplastic pollution to support mitigation planning.
Modeling the transport of microplastics along river networks
AI summary Read the abstract
Researchers built a mathematical model to predict how microplastics travel through river networks, combining water flow dynamics with estimates of human plastic inputs. They tested the model against real-world data from three river systems worldwide and found it reliably predicted microplastic concentrations. The tool could help identify pollution hotspots and guide cleanup priorities across entire river basins.
Dispersal and transport of microplastic particles under different flow conditions in riverine ecosystem
AI summary Read the abstract
Researchers developed a particle-tracking model combined with hydrodynamic simulation to study how microplastics travel through river systems under different water flow conditions. They found that flow speed, turbulence, and river channel features significantly influence where microplastics accumulate and how far they travel. The study provides a useful tool for predicting microplastic transport patterns and identifying pollution hotspots in river ecosystems.
Multi-Type Microplastic Migration Model Driven by River Hydrodynamic Conditions
AI summary Read the abstract
Scientists built a model that predicts how different types of microplastics move through rivers, some float and travel quickly downstream, others sink to the riverbed, and some stay suspended in the water depending on their size, shape, and material. This matters because most of the microplastics found (over 70%) were smaller than half a millimeter, tiny enough to be easily ingested by fish and potentially end up in our drinking water or food supply, so understanding where they travel and accumulate can help target cleanup efforts and pollution control where they're needed most.
The Plastic Pathfinder: A Macroplastic Transport and Fate Model for Terrestrial Environments
AI summary Read the abstract
Researchers introduced the Plastic Pathfinder, a computer model that simulates how plastic waste moves across land through wind, rain, and river systems before reaching the ocean. The model helps identify key transport pathways and accumulation hotspots, which is critical information for targeting plastic pollution interventions.
