ClearMathematical modeling of microplastic abundance, distribution, and transport in water environments: A review
This review surveys mathematical models used to predict how microplastics move through and accumulate in rivers and oceans.

The Complex Dynamics of Microplastic Migration through Different Aquatic Environments: Subsidies for a Better Understanding of Its Environmental Dispersion
This review explores how microplastics move through different aquatic environments, from rivers and lakes to estuaries and oceans, focusing on the physical properties that drive their transport. Researchers found that factors like particle density, size, shape, and biofouling all influence where microplastics accumulate and how far they travel. Understanding these migration dynamics is essential for predicting contamination patterns and designing effective cleanup strategies.

Modelling Microplastic Dynamics in Estuaries: A Comprehensive Review, Challenges and Recommendations
This comprehensive review examines how process-based computer models have been used to simulate microplastic transport and fate in estuaries — the complex, tidal zones where rivers meet the sea. It evaluates different modeling approaches for capturing hydrodynamics, particle behavior, and interactions with sediment, identifying key gaps and inconsistencies in how microplastic properties are represented. Better estuarine models are needed to predict where plastics accumulate, how long they persist, and what risks they pose to coastal ecosystems and the communities that depend on them.
