Availability and mobility of microplastics in river sediments
AI summary Read the abstract
This thesis investigated the presence of microplastics in urban river sediments, assessed factors influencing their distribution, and developed a 3D mathematical model to simulate their transport and dispersal. The findings contribute to environmental risk assessment and management of microplastic pollution in freshwater systems.
This research study systematically investigated the presence of different microplastics in urban river sediments, assessed the factors which influence microplastics distribution, and evaluated the environmental risks of microplastics on sediment quality. Furthermore, the research project developed a three-dimensional mathematical modelling framework on the dispersal and transport processes of different sedimental microplastics. The outcomes of this research study will contribute to the informed management of waste plastics and formulation of effective mitigation measures.

Researchers modeled microplastic transport, deposition, and burial in river bed sediments under varying hydrological conditions. River bed sediments were found to act as long-term reservoirs for microplastics, with periodic high-flow events temporarily resuspending and redistributing particles.
Microplastic dynamics within turbulence for improved modelling and monitoring strategies
AI summary Read the abstract
This study developed improved models for predicting microplastic distribution and transport within river systems, accounting for turbulence effects and the exchange between suspended load and bedload. The authors identified that existing sediment transport models fail to capture the behavior of low-density plastic particles in turbulent flow. More accurate models are needed to predict where microplastics accumulate in rivers and estimate their flux to the ocean.
Mathematical modeling of microplastic abundance, distribution, and transport in water environments: A review
AI summary Read the abstract
This review surveys mathematical models used to predict how microplastics move through and accumulate in rivers and oceans. Researchers categorized existing approaches by environment type and modeling method, identifying strengths and gaps in current simulation tools. The study highlights the need for better models that account for real-world complexity, including particle fragmentation and biofouling, to improve predictions of where microplastics end up.
Transport processes of microplastic particles in the fluvial environment : erosion, transport and deposition
AI summary Read the abstract
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.
