Microplastics have become ubiquitous in our rivers, lakes and reservoirs, detrimentally impacting ecosystems. Via high-fidelity numerical simulations, the project aims to advance our understanding of the complex interplay between dispersed microplastics and key fluvial processes including turbulence, sediment transport and free-surface wave dynamics. The project intends to buildup a data-base containing high-resolution data of the occurrence, trajectories and distribution of microplastics. The outcome is anticipated to be invaluable in improving microplastic transport models, standardisation of sampling and quantification techniques, and in designing innovative mitigation technologies for microplastic collection.

微塑料在我们的河流，湖泊和水库中变得无处不在，对生态系统产生了不利影响。通过高保真数值模拟，该项目旨在促进我们对分散的微塑料和关键河流过程之间复杂相互作用的理解，包括湍流，沉积物传输和自由表面波动动力学。该项目打算建立一个数据库，其中包含发生的高分辨率数据，轨迹和微塑料的分布。预计该结果在改善微型传输模型，采样和定量技术的标准化以及设计微型塑料收集的创新缓解技术方面将是无价的。
