ClearA 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.
Modeling the transport of microplastics along river networks
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.
On modeling the fate of microplastics along river networks
Researchers developed and applied a modeling framework to simulate the fate and transport of microplastics along river network systems, treating rivers as key conduits transferring land-based microplastic pollution to marine environments. The model accounted for particle ingestion risks to aquatic organisms and evaluated the long-term persistence and transport dynamics of microplastics across freshwater networks.

Modeling microplastic dynamics in riverine systems: fate and transport analysis
Researchers developed a computer model to simulate how microplastics travel through river systems, accounting for how they enter from human activities and how they settle, resuspend, and deposit along riverbanks. The model was applied to the Tame River in the UK using four different scenarios based on plastic particle types like fibers, fragments, and pellets. The study provides a tool for predicting where microplastics accumulate in rivers, which could help target cleanup and monitoring efforts.

Researchers developed a particle-tracking model combined with hydrodynamic simulation to study how microplastics travel through river systems under different water flow conditions.

Quantifying the impact of biofouling on microplastic transport: a modeling study

A reduced-complexity numerical model was developed to simulate how microplastics erode, transport, and deposit through river systems, applied to the Têt River in France.

Researchers reviewed current mathematical models for tracking how plastic debris — including microplastics and nanoplastics — moves through freshwater environments, finding that while many principles from existing particle models apply, plastic's unique combination of high persistence, low density, and extreme size range makes its behavior far more varied and complex to predict.
