Abstract

ABSTRACT The present study examines the effectiveness of six LID-BMPs in urban runoff reduction in Neyshabour city, Iran. The validated Storm Water Management Model (SWMM5.1) was employed to assess the effectiveness of LID-BMPs in mitigating runoff volume. The hydrological model was calibrated and validated with nine in-site measured flood hydrographs. 11 LID-BMP scenarios were planned to determine the most effective combination of LID-BMPs. The results showed that according to the site conditions, Infiltration Trench (IT) and Rain Barrel (RB) practices with 22.2% and 0.4% reduction rates had the highest and lowest efficiency in reducing urban runoff. By assessing various combinations of LID-BMPs, it was found that the combination of IT, Bio-Retention (BR), Stormwater Dry Ponds (SDP), Porous Pavement (PP), and Rain Garden (RG) provides the most effective strategy for runoff management. Despite the high efficiency of LID-BMPs in reducing runoff, they are not able to completely handle the consequences of urbanization.

评估LID BMP对城市子流域城市径流减少的影响

摘要本研究考察了六种LID BMP在伊朗内沙布尔市减少城市径流方面的有效性。采用经验证的雨水管理模型（SWMM5.1）来评估LID BMP在减少径流量方面的有效性。水文模型通过九条现场测量的洪水过程线进行了校准和验证。计划了11个LID-BMP场景，以确定LID-BMP的最有效组合。结果表明，根据不同的场地条件，采用22.2%和0.4%的渗槽和雨桶两种方法对城市径流的减少效率最高和最低。通过评估LID BMP的各种组合，发现it、生物滞留（BR）、雨水干池（SDP）、多孔路面（PP）和雨水花园（RG）的组合为径流管理提供了最有效的策略。尽管LID BMP在减少径流方面效率很高，但它们无法完全应对城市化的后果。

期刊介绍： Urban Water Journal provides a forum for the research and professional communities dealing with water systems in the urban environment, directly contributing to the furtherance of sustainable development. Particular emphasis is placed on the analysis of interrelationships and interactions between the individual water systems, urban water bodies and the wider environment. The Journal encourages the adoption of an integrated approach, and system''s thinking to solve the numerous problems associated with sustainable urban water management. Urban Water Journal focuses on the water-related infrastructure in the city: namely potable water supply, treatment and distribution; wastewater collection, treatment and management, and environmental return; storm drainage and urban flood management. Specific topics of interest include: network design, optimisation, management, operation and rehabilitation; novel treatment processes for water and wastewater, resource recovery, treatment plant design and optimisation as well as treatment plants as part of the integrated urban water system; demand management and water efficiency, water recycling and source control; stormwater management, urban flood risk quantification and management; monitoring, utilisation and management of urban water bodies including groundwater; water-sensitive planning and design (including analysis of interactions of the urban water cycle with city planning and green infrastructure); resilience of the urban water system, long term scenarios to manage uncertainty, system stress testing; data needs, smart metering and sensors, advanced data analytics for knowledge discovery, quantification and management of uncertainty, smart technologies for urban water systems; decision-support and informatic tools;...
