Abstract Combined sewer overflows (CSOs), the discharge of untreated sewage mixed with stormwater into surface waters, are expected to increase under climate change as a result more extreme rainfall. Blue–green infrastructure (BGI), such bioretention cells and porous pavements, can help reduce amount entering combined systems, thus reducing CSO discharge. However, our understanding potential for BGI mitigate CSOs in future is still lacking, performance typically evaluated individual elements fixed implementation areas historical conditions or limited scenarios. In response, this study investigates 30 combinations rates prevent increases range scenarios an urban catchment near Zurich, Switzerland. Median total annual rainfall, projected by much 46%, could double median volume frequency up 52%. Four that include show most promise climate; given diverse responses distinct rainfall patterns, their enhance reduction across varying patterns. also likely become cost-effective climatic led larger reductions obtained through BGI. there trade-off between robustness cost-effectiveness, since capacity scales rate but cost-effectiveness declines.

Challenges and Innovations in Urban Drainage Systems: Sustainable Drainage Systems Focus

Water, Год журнала: 2024, Номер 17(1), С. 76 - 76

Опубликована: Дек. 31, 2024

Sustainable Urban Drainage Systems (SUDS) represent a paradigm shift in stormwater management, offering holistic solutions to urban water challenges. This review examines SUDS principles, design strategies, effectiveness and barriers implementation. prioritize infiltration mimic natural hydrological processes reduce flood risk, improve quality support ecosystems environments. Effective integrates different components such as permeable pavements, green roofs, rain gardens, tailored the local context. Evidence suggests that well-designed can mitigate peak flows, runoff volumes, purify water. However, widespread adoption include lack of awareness, upfront costs, regulatory complexity. Overcoming these will require collaborative stakeholder action education, policy support, funding opportunities. Future research should focus on optimizing design, assessing long-term performance, quantifying socio-economic benefits. By integrating into landscapes, cities strengthen resilience, promote sustainability, enrich life.

Informing Risk Hotspots and Critical Mitigations for Rainstorms Using Machine Learning: Evidence from 268 Chinese Cities

Environmental Science & Technology, Год журнала: 2025, Номер unknown

Climate change is exacerbating rainstorms, increasing the risk of flooding and threatening urban sustainability, which could undermine climate action. Here, we propose a machine learning-based framework to assess heterogeneous risks identify critical mitigation measures for rainstorms across 268 Chinese cities. Nighttime light serves as proxy functionality, meteorological, socio-economic, infrastructural factors are incorporated uncover underlying impact mechanisms. The Causal Forest (CF) model identifies 150 250 mm monthly rainstorm totals thresholds, with significant negative impacts in hotspots eastern north-central China. Additionally, Random SHAP (RF-SHAP) analysis highlight effective strategies, including well-developed drainage bridges, expanded road networks, sufficient dams. Fixed Effects (FE) reveals that greatest occur spring, particularly April, followed by autumn winter both 50 thresholds. Our results demonstrate three models complement validate each other, enhancing reliability estimates. This novel leverages learning inform evidence-based mitigation, contributing achievement Sustainable Development Goals 11 13─building resilient cities combating change.

Realistic exposure scenarios in combined sewer overflows: how temporal resolution and selection of micropollutants impact risk assessment

Water Research, Год журнала: 2025, Номер 278, С. 123318 - 123318

Organic micropollutants in combined sewer overflows (CSOs) pose a potential risk to aquatic ecosystems. Previous studies mainly reported event mean concentrations (EMCs) and often focused on small number of substances. This study presents realistic exposure scenarios using high-temporal resolution (10-minute) data from 24 events at two CSO sites. We analyzed 49 dissolved organic for all 198 four events, including pharmaceuticals, pesticides, road-related compounds, which we detected 83 substances least once. From these, assessed the mixed chemical by applying acute quality criteria evaluated how assessment outcome changes aspects: temporal selection Our results reveal that total quotients (RQtot) can vary greatly within with 10-minute capturing peak are missed EMCs. Using EMCs underestimates maximum RQtot an median factor 4.9, up 6.9. When comparing 20 Swiss Waters Protection Ordinance broader list commonly CSOs comprehensive substances, estimated increases between 1.1 2.3-fold. values exceed threshold 1 75 % requiring further dilution receiving water body. All three pollutant classes (pharma, pesticide, road) drive risk, no specific phase during overflow consistently poses higher than other phases, challenges design effective mitigation measures. Furthermore, presented here offer essential input future ecotoxicological research as they high short-term fluctuations whose ecological significance is still largely unknown.
