Data and code for: Socioeconomic and hydrodynamic controls on microplastic export in the Three Gorges Reservoir
Summary
Researchers built a computer model to track how tiny plastic particles (microplastics) flow through China's massive Three Gorges Reservoir, factoring in things like local economic activity, rainfall, and water movement patterns. This matters because reservoirs like this one supply drinking water to millions of people, and understanding what drives microplastic pollution—and how it might change through 2065—can help communities and policymakers reduce contamination before it reaches your tap. Note: this dataset paper shares the tools and data behind the study rather than the full results, so it's a resource for other scientists to build on.
This dataset and code repository support the findings presented in "Socioeconomic and hydrodynamic controls on microplastic export in the Three Gorges Reservoir". It contains: (i) observational data for model validation, including environmental conditions (precipitation, dissolved oxygen, water temperature, hydraulic residence time), compiled microplastic physicochemical characteristics and spatial abundance from published field studies (2016, 2022), and district-level GDP; and (ii) process-based modeling code and simulation outputs for microplastic export flux estimation and future scenario projections (2015–2065). All data sources, software requirements, and script execution order are documented in the read me file.
