A process-based source-to-sea model simulating Escherichia coli shows CSO discharge concentrations vary widely (4.6–7.3 log10 CFU 100 ml−1) across the catchment.
- Why it matters: Peak microbial pollution in coastal bathing waters needs accurate prediction to protect public health, especially as urban pressures and heavy rainfall intensify.
- What they did: Using a three-year retrospective simulation (2017–2019), the model tracked Escherichia coli emissions, transport, and fate from sources to beaches, with 89% simulation accuracy and CCDF-based peak representation.
- The result: At the inland water outlet, 99th percentile concentrations (4.0 log10 CFU 100 ml−1) are dominated by local CSO emissions, while 90th percentile values (3.6 log10 CFU 100 ml−1) reflect cumulative upstream CSO and effluent contributions, enabling hotspot identification and mitigation support.
