“…1 conceptualizes the surface runoff of SWMM5-LID. In the previous versions of SWMM, two equations, namely, Horton and Green-Ampt were used to calculate the infi ltration rate [8]. In the latest version, however, Soil Conservation Service Center Equation (SCS-CN) was introduced.…”

2012) Flood reduction analysis on watershed of LID design demonstration district using SWMM5, Desalination and Water Treatment, 38:1-3, 255-261, A B S T R AC TUrban development is the primary cause of the expansion of impervious areas. Urbanization reduces infi ltration of rainwater, increases runoff volume, and fi nally has an effect on the hydrological cycle and urban environment. To solve these problems, Low Impact Development (LID) methods have been used to restore the natural hydrology of predevelopment sites using site design techniques such as infi ltration, evaporation, and retention. SWMM5 has been developed as a model to analyze the hydrologic impacts of LID facilities. This study performed hydrologic analysis and evaluated the fl ood reduction effect of the Jangjae Stream watershed by the design of LID facilities of the rainwater management demonstration district of AsanTangjung New Town (Korea). LID facilities in this study were comprised of infi ltration trench, rain barrel, vegetation swale, etc. SWMM5 was calibrated using rainfall data of the 7th and the 14th of July, 2011 and was verifi ed using rainfall data of the 10th and the 11th of August, 2011. This study analyzed fl ood reduction effect on 50 to 100 y return period. Based on the results of this study, the reduction of fl ood peak discharge by each return period of storms was estimated to be about 7 to 15%.

“…The model can be used to optimize the design of LID practices by simulating various scenarios and evaluating the performance of different configurations. Moreover, SWMM can be employed to assess the impact of LID practices on the hydrology and water quality of a catchment and compare the performance of different LID practices [27][28][29][30][31][32]. Numerous hypotheses have proposed regarding the influence of urban rainfall in the context of LID technologies.…”

Low-impact developments (LIDs) have emerged as effective strategies for mitigating the adverse impacts of urbanization on river environments. This study aims to enhance river environment quality by examining the effects of LIDs and land use/cover change (LUCC) in the context of river environment and hydrological conditions. Using the Stormwater Management Model (SWMM) in an urban river setting, the study investigates the impact of LIDs on urban river water volume. An analysis of river runoff quality and quantity is conducted, followed by the development of an optimal river water regulation scheme through a multi-objective ecological scheduling model. The results reveal that the incorporation of LIDs can substantially decrease river runoff yield for varying recurrence periods of design rainstorms. Consequently, the flood peak reduction rate ranged from 10% to 18%, and the flood volume experienced a reduction of 10–29% in the study area. The combination of river water regulation, LIDs and LUCC leads to a decrease in river water volume within the lower river channel by up to 47% especially in a typical dry year and dry season, accompanied by a decline in river flow velocity and water self-purification capacity. A risk-based multi-objective stochastic optimization model is employed to ensure sustainable management of urban river runoff in terms of both quantity and quality. This research contributes to the advancement of knowledge in sustainable basin management practices and offers practical insights for policymakers involved in the management of water resources and environmental conservation in semi-arid basins.

Dianchi Lake urban wetland park in Kunming is an important component of Dianchi lakeside wetlands, it is of great significance to the urban development and ecological protection of Kunming. To solve the problem of non-point source pollution of Dianchi Lake basin, the Dianchi Lake Pan-Asian International Urban Wetland Park is taken as an example, the rapid artificial infiltration treatment system and the comprehensive constructed wetland treatment system were designed for Dianchi Lake urban wetland park, and various design parameters and its influencing factors have been analyzed. After the deep treatment by the treatment system, the water quality reached the standards of landscape water. The planning of water system for Dianchi Lake urban wetland park provides a reference for designing plateau lake urban wetland parks.
