“…This can disrupt people's daily activities, hinder mobility, and cause huge economic losses. Costs for repairing flooddamaged infrastructure can also strain government and community budgets (Bibi & Kara, 2023a). Floods can also result in significant economic losses for individuals, businesses, and governments.…”

Urbanization and climate change have increased the risk of flooding in cities. Sustainable Urban Drainage Systems (SUDS) offer a promising approach to mitigate these risks by managing stormwater runoff. This study aims to conduct a meta-analysis to assess the effectiveness of SUDS in reducing urban flood risks. This research is a type of meta-analysis research. The study investigated the impact of SUDS on flood reduction. Data on different types of SUDS, precipitation events, and flood risk metrics were extracted. Standardized mean differences (SMDs) are calculated to measure the overall impact of SUDS on flood reduction. The meta-analysis revealed a significant positive effect of SUDS on reducing urban flood risks. The effect size varied depending on the type of SUDS and the severity of the rainfall event. Overall, SUDS demonstrated effectiveness in mitigating flood risks associated with various storm intensities with effect size value = 0.801. This meta-analysis provides robust evidence for the effectiveness of SUDS in reducing urban flood risks. The findings support the wider adoption of SUDS as a key strategy for sustainable urban development and flood risk management.

“…During the rapid development of urbanization, natural landscapes were transformed into impervious surfaces and energy consumption increased. As a result, the city will be seriously vulnerable to environmental and ecological changes such as water and air quality and urban runoff [23,24]. In this paper, the Pu River Basin is taken as the research objection, and the application evaluation before and after basin urbanization has been analyzed.…”

With the acceleration of urbanization in a river basin, the changes in the underlying surface structure of the basin are more and more intense, which causes frequent floods. This article aims to analyze the applicability of the HEC-HMS model in flood simulation in urbanization basins and the influence of land use changes on catchment runoff. Pu River Basin is a typical urbanization basin and is taken as the research project. Based on land use changes, soil types, and long-term hydrological data in the Pu River Basin, the HEC-HMS hydrological model is constructed using GIS and HEC-geoHMS. Then, the relative error of flood peak and runoff, Nash–Sutcliffe efficiency coefficient, and correlation are used to evaluate the model simulation rating. The results show that the HEC-HMS model is suitable for an urbanization basin, and its performance grade before urbanization is better than that after urbanization. Finally, sensitivity analysis of nine parameters on model performance shows that curve number, initial abstraction, imperviousness, and time lag are the main parameters. The research results will provide a reference for urbanization basins’ flood simulation and stormwater management.

“…Moreover, stormwater flooding has become a global concern, reflecting the need for well-defined management strategies to address flooding hazards exacerbated by climate change [22]. Furthermore, studies have shown that the current stormwater management infrastructures are incapable of accommodating the expected peak runoff caused by climate change, which might lead to a higher frequency and intensity of floods in urban catchments [23]. Studies have also shown that one of the major causes of urban flooding is due to the fact that the current drainage systems have been designed without the considerations of both climate change and urbanization [24].…”

Urban sprawl has resulted in great losses of vegetation areas, an increase in impervious surfaces, and consequently the direct flow of stormwater into stream channels (i.e., the immediate flow of stormwater into stream channels, in comparison to the indirect flow that is represented by practices aiming to retain stormwater for a certain period of time and treat the polluted stormwater prior to flowing into the stream channels such as detention/retention basins, among others). Stormwater management systems such as catch basins (CBs) are needed to reduce the effect of stormwater runoff. Preventative maintenance, repair, and replacement of CBs are critical to achieve stormwater management best practices. Those practices prevent the blockage of the stormwater system, limit the pollutants in storm sewers, and reduce the risk of flooding. However, no preceding research studies have been conducted to model and simulate the serviceability of CBs and to determine optimal strategies for operating CBs. To that extent, this study establishes a framework to develop and validate an optimal and adaptive maintenance, repair, and overhaul (MRO) strategy for CBs. In relation to that, an agent-based model (ABM) integrated with Monte Carlo simulation was developed for all 560 CBs in New York City’s District 5 and was statistically validated using 99% confidence intervals. The MRO parameters were optimized to minimize the total cost of the system and attain the desired level of serviceability of CBs. Sensitivity analysis was conducted to guide the maintenance planning process of CBs and reveal the effect of the input parameters on the model’s behavior. In addition, ten thousand Monte Carlo iterations were simulated to derive the distributions of the defined parameters. The results proved that in order to minimize the overall cost of repair, maintenance, and replacement of CBs and attain a minimum serviceability threshold of 80%, the following optimal MRO policy needs to be implemented: having seven service crews (where service crews are human resources (i.e., MRO teams) needed to perform the required maintenance, repair, and replacement work), implementing a replacing policy, and replacing CBs after five maintenance periods. The findings revealed that the service crews represent the most critical parameter in affecting the total cost and serviceability of CBs. This research contributes to the existing literature by offering a better knowledge of the management process of CBs and devising optimal MRO strategies for properly operating them. Ultimately, this research helps decision-makers and engineers increase the lifespan of CBs and limit their risks of breakdown, increase their efficiency, and avoid unnecessary costs. The proposed model is flexible and can be implemented to any geographical area and with other model/system parameters, which makes it adaptive for any scenario and area presented by the user. Finally, maintaining stormwater management practices helps in protecting the environment by decreasing the demand on stormwater systems, reducing flooding, protecting people and properties, promoting healthier rivers, and consequently creating more sustainable communities.
