Special Issue Information

Dear Colleagues,

Over the last three decades, rapid urbanization accompanied by great achievements in construction has resulted in a series of problems of urban ecology, environment, resources and security in urban areas. The environmental issues are largely perceived as obstacles impeding sustainable economic development.

A series of practices, including the publication of mandatory regulations, policy support, standard updates and revisions, etc., have been proposed to address these drainage problems in China. Alongside the reconstruction and upgrading of traditional drainage infrastructures (gray infrastructures), green stormwater infrastructures (GSIs) and low-impact developments (LIDs) are other important components of modern urban drainage engineering practices. GSIs provide an alternative approach to urban sustainable stormwater management, and is a relatively new method even in developed countries.

In order to address the problems of the urban environment and promote the construction of GSIs, a new concept and related technical methodology, called “sponge city,” was proposed in China. National pilot city and demonstration city mode were adopted to promote this the concept. Until now, sponge city-related construction has been implemented in 90 national pilot and demonstration cities, and more than 600 cities have prepared special sponge city development planning. GSIs have a greater application potential at the building and community scales. GSI practices are more feasible in newly developed buildings and communities than in older urban sections. Accompanied by the process of urbanization, a large number of new districts are developing or will be developed in the near future; these provide an important precondition for the implementation of GSIs.

This Special Issue calls for attention and discussion on up-to-date findings of urban building and green stormwater infrastructure (e.g., monitoring, mechanism and technology), as well as the frontiers of planning technics and approaches to actualize the sustainable drainage. Potential topics include, but are not limited to, the following:

  • Runoff pollution characteristics of buildings and residential areas;
  • Advances of technologies or methods applied to building drainage;
  • Stormwater management mechanism (gray and green) in the building and community;
  • New technologies for stormwater management (gray and green) in the building and community;
  • Advances in technologies or methods for the planning and design of the building and community drainage system;
  • Sustainable assessment of drainage system in the building and community aided by new data/approaches;
  • Drainage modeling and uncertainty analysis in the building and community;
  • Theoretical and empirical studies on sustainable drainage and sponge city construction;
  • Building drainage in extreme precipitation and climate change.

Technical System for Urban Stormwater Carrying Capacity Assessment and Optimization

The combined effects of rapid urbanization and climate change are increasingly exacerbating the risk of urban flooding. This study develops a data-efficient framework for estimating a city’s Urban Stormwater Carrying Capacity (USCC)—the maximum stormwater volume that can be safely infiltrated, stored, and conveyed. The framework couples three rainfall scenarios—frequent, heavy, and extreme—with nine widely adopted drainage and storage measures, ranging from green spaces and permeable pavements to pipes and underground emergency reservoirs, and expresses USCC through a streamlined water-balance equation. Applied to the 24 km2 Zhangmian River district in Weifang, China, the framework yields capacities of 4.84, 5.86, and 9.80 × 106 m3 for the three scenarios, respectively; underground reservoirs supply ≈ 40% of the extreme-event capacity. Sensitivity analysis shows that increasing the imperviousness coefficient from 0.65 to 0.85 raises peak drainage demand by 30.8%, whereas halving reservoir depth lowers total capacity by 27.8%. Because the method requires only rainfall depth, land-cover data, and basic facility dimensions, it enables rapid, transparent scenario testing and helps planners prioritize cost-effective upgrades. The approach is transferable to other cities and can be extended to incorporate water quality or digital-twin modules in future research. Full article

Green roofs (GRs) are increasingly implemented for stormwater management, and retrofitting conventional roofs is emerging as a key strategy for climate change resilience. However, their impact on diffuse pollution, particularly regarding total organic carbon (TOC) and pollutant mass transport, remains insufficiently understood, especially in aged substrates. This study evaluated and compared the runoff quality from aged GRs and ceramic roofs (CRs) by analyzing TOC, pH, electrical conductivity (EC), first-flush occurrence and intensity, and pollutant release patterns. Results showed that GR retrofitting could help mitigate acid-rain effects due to its elevated pH. Despite higher TOC and EC concentrations in runoff, GRs remained within acceptable water quality limits and exhibited a more gradual release of organic matter over time compared with CRs. Statistical analysis revealed that pollutant concentrations in CR runoff followed Lognormal and Weibull distributions, while GR runoff was best described by Normal, Lognormal, and Weibull distributions. These findings reinforce GRs as a viable stormwater management strategy but highlight the need for full runoff treatment when used for rainwater harvesting. The results also emphasize the importance of tailored statistical models to enhance runoff predictions and optimize GR performance in urban water management. The results provide valuable insights for urban planners and policymakers by reinforcing the potential of GRs in stormwater quality management and supporting the development of incentives for green infrastructure. Future research should expand to different GR configurations, climates, and maintenance practices to enhance the understanding of long-term hydrological and water quality performance. Full article

As eco-friendly complexes develop, interest in eco-friendly facilities is also growing. Particularly, rainwater harvesting facilities have demonstrated positive effects by reducing runoff to mitigate urban flooding and recycling water for landscaping and cleaning purposes. In this study, we analyzed the quality of stored rainwater, which has improved by excluding initial runoff, and examined the temperature reduction effects of road sprinkling and mist spraying. Road sprinkling decreased the temperature of asphalt and permeable pavements by approximately 15 °C, with permeable pavements maintaining the reduced temperature for a longer time. The indoor experiments with mist spraying showed a temperature reduction effect of 3.4 °C. The quality analysis of the rainwater harvesting facilities revealed that the water quality was suitable for irrigation and landscaping by excluding the initial runoff. This study confirms the effectiveness of rainwater utilization in mitigating urban heat islands and improving water circulation within cities. Full article
