Dynamics and dispersion of microplastics in turbulent shallow water flows

微塑料在我们的河流、湖泊和水库中无处不在，对生态系统造成了不利影响。通过高保真数值模拟，该项目旨在增进我们对分散微塑料与关键河流过程之间复杂相互作用的理解，包括湍流、泥沙输送和自由表面波动力学。该项目打算建立一个数据库，其中包含微塑料的发生、轨迹和分布的高分辨率数据。预计这一成果将对改进微塑料运输模型、使采样和量化技术标准化以及为微塑料收集设计创新的缓解技术方面具有非常宝贵的价值。

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.
