“…In particular, this research confirms and expands previous research on the retention of stormwater and the reduction of peak stormwater runoff using decentralized systems. Stormwater peak runoff reduction in Kuala Lumpur, Malaysia, using low impact development systems (LID) consisting of vegetated swale and rain garden could only be reduced by up to 19% (for rainfall of between 70 and 90 mm) and up to 27% (for rainfall of up to 70 mm) [42].…”

The objective of this study was to illustrate the urban flood resilience and sustainability improvement potential by integration of decentralized water management systems in sustainable urban regeneration projects. This paper discusses sustainable and resilient urban regeneration potentials using the example of an industrial compound (ICs) conversion in Seoul, South Korea. Urban flood vulnerability has been a concern globally due to land use changes, limited capacity of existing stormwater management infrastructures and the effects of climate change. Due to their comparably low building density, ICs can effectively contribute to the separation and decentralized retention and infiltration of stormwater. However, no sustainable and resilient conversion examples of ICs have been realized in Seoul so far. After identification of a representative IC, its exemplary sustainable conversion with implementation of decentralized water management infrastructures were designed. The rainwater collection, retention and infiltration system was dimensioned in order to create a stormwater discharge-free property. The qualitative and quantitative analysis of the improvement potentials before and after the conversion unveiled that this conversion contributes also to the improvement of the neighborhoods' sustainability, spatial quality and resilience to disasters. The research results are transferable to other urban ICs and are a good practice example for sustainable and resilient regeneration of existing urban districts.

“…found that rainfall intensity was the primary influencing factor for water quantity concerns while the rain garden proportion impacted water quality. Rezaei et al (2019) also saw a positive impact on water quality from the implementation of LID. The model was most sensitive to the percent imperviousness as it significantly impacted runoff and peak flow.…”

This review summarizes over 280 studies published in 2019 related to the characterization, control, and management of urban stormwater runoff. A summary of quantity and quality concerns is provided in the first section of the review, serving as the foundation for the following sections which focus on the control and treatment of stormwater runoff. Finally, the impact of stormwater control devices at the watershed scale is discussed. Each section provides a self-contained overview of the 2019 literature, common themes, and future work. Several themes emerged from the 2019 literature including exploration of substrate amendments for improved water quality effluent from stormwater controls, the continued study of the role of vegetation in green infrastructure practices, and a call to action for the development of new models which generate reliable, computationally efficient results under the physical, chemical, biological, and social complexity of stormwater management. © 2020 Water Environment Federation • Practitioner points • Over 280 studies were published in 2019 related to the characterization, control, and treatment of urban stormwater. • Studies on bioretention and general stormwater characteristics represented the two most common subtopics in 2019. • Trends in 2019 included novel substrate amendments, studies on the role of vegetation, and advancements in computational models.

“…Therefore, if the vulnerability of cities is caused by the short duration with the low return period, LIDs should be first considered, otherwise detention ponds should be given the priority. Rezaei et al [23] also demonstrates that detention ponds are the proper solution to the flood control for long durations. In this study, the effect of detention ponds for flood reduction did not perform very well because those ponds were allocated in the existing parks and schools of the study area and these spaces were already designed at the end of the drainage system.…”

Sustainability and resilience are up-to-date considerations for urban developments in terms of flood mitigation. These considerations usually pose a new challenge to the urban planner because the achievement of a sustainable design through low impact development (LID) practices would be affected by the selection and the distribution of them. This study proposed a means to optimize the distribution of LIDs with the concept of considering the reduction of the flood peak and the hydrologic footprint residence (HFR). The study region is a densely populated place located in New Taipei City. This place has been developing for more than 40 years with completive sewer systems; therefore, the design must consider the space limitations. The flood reduction induced by each LID component under different rainfall return periods was estimated, and then the detention ponds were also conducted to compare the improvements. The results showed that the performance of LIDs dramatically decreased when the return periods were larger than ten years. A multi-objective genetic algorithm (MOGA) was then applied to optimize the spatial distribution of LIDs under different budget scenarios, and to decide the priority of locations for the LID configuration. Finally, the Monte Carlo test was used to test the relationship between the optimal space configuration of LIDs and the impermeability of the study region. A positive correlation was uncovered between the optimal allocation ratio and the impermeable rate of the partition. The study results can provide general guidelines for urban planners to design LIDs in urban areas.
