Abstract Quantitative simulation of urban waterlogging using computer models is an effective technical means for stormwater management, especially predicting and preventing waterlogging. In this study, a city in northern Anhui Plain, China, was selected as the study site. The Storm Water Management Model applied to simulate dynamic changes pipeline overload, node overflow, discharge port runoff characteristics from three perspectives: surface runoff, pipe network transmission, flow control low-impact development. operation rainwater under different return periods real-time were simulated seek solutions problems caused by flat terrain slow drainage. results revealed that primary source rainfall area, with coefficient 0.599. drainage optimized expanding diameter ≤ 1.5 mm ≥ 2 mm. water reduction rate more than 50%, overload did not occur after optimization. Therefore, sinking greenspace technology optimization methods can reduce

Growing urbanization has increased impermeable surfaces, raising and polluting stormwater runoff, exacerbating the risk of urban flooding. Effective management is essential to curb sedimentation, minimize pollution, mitigate This systematic literature review from Web Science Scopus between January 2000 June 2024 presents hydrodynamic separation (HDS) technologies. It sheds light on significant issues that water faces. HDS classified into four categories: screening, filtration, settling, flotation, based treatment mechanisms. The results show a shift traditional standalone physical separations multi-stage hybrid processes with nature-based solutions. great advantage these approaches they combine different mechanisms integrate ecological sustainability manage better. findings showed future research will examine AI-assisted technologies, biochar-enhanced green infrastructure systems. When adopting an integrated approach, system perform like natural remove pollutants effectively better monitoring controls. These technologies are intended fill existing voids, especially in removing biological contaminants new (e.g., microplastics pharmaceutical substances). In long term, help enforce Sustainable Development Goals (SDGs) orient areas developing countries towards meeting circular economy objective.

Abstract In May 2024, southern Brazil experienced a severe flood that caused widespread devastation, particularly in the metropolitan area of Porto Alegre. This disaster resulted from rare combination atmospheric conditions: heatwave stalled cold front, leading to prolonged and intense rainfall. The claimed 183 lives, left 27 missing, displaced many more. Notably, flood's peak coincided with satellite observations both SWOT Sentinel‐2, providing valuable snapshot disaster. To assess scope, volume, we integrate these data FABDEM topography. SWOT's water height measurements, evaluated situ data, underscore its monitoring potential. estimated floodwater volume was 1.5 billion . While primarily damaging croplands, directly affected 420,000 individuals study region, 16% identified as socially vulnerable. These findings offer insights into distribution contribute future dynamics research, mitigation strategies, preparedness.

According to statistics, the majority of Louisiana's urban coastal area is low-income, out which a significant percentage susceptible issues dealing with hazards and relevant consequences. On other hand, increasing number along Mexican Gulf Coast has become severe concern for governors. In this study, social vulnerability extreme floods New Orleans evaluated through four phases. The indicators are identified, using statistical analysis process most important determined. Also, Social Vulnerability Index (SVI) estimated mapped, flood risk maps generated. Finally, by merging SVI map map, exposure results revealed that key factors account 78.60% variation in overall dataset include age (31.3%), urbanization (21.5%), employment status (13.7%), education level (12.1%). output research can help stakeholders decision-makers lessen impact flooding on life vulnerable communities living areas.
