典型LID设施多尺度径流调控效应研究
Study on the runoff regulation effects of typical low impact development facilities in multiple scale regions
摘要
Abstract
[Objective]In order to investigate the role of sponge cities in mitigating urban waterlogging by selecting the Jincun development area of Jincheng City as a research area and analyzing the regulation effects of low impact development(LID)facili-ties on runoff and waterlogging at different spatial scales.[Methods]A coupled urban stormwater and waterlogging model was developed by integrating the Storm Water Management Model(SWMM)and the two-dimensional module of InfoWorks ICM.The model simulated various storm scenarios and LID layout schemes to analyze rainfall-runoff processes and waterlogging characteris-tics in plots,drainage zones,and regions.[Results]The findings indicated that LID facilities effectively reduced runoff peak values,decreased total runoff,accelerated runoff recession,and mitigated overflow nodes and overloaded pipe segments.They also significantly reduced areas affected by waterlogging and lowered water depths.The regulation effect of LID facilities showed minor variation across different spatial scales and performed well within a 1 to 5-year recurrence period.Specifically,under 1-year recurrence period rainfall,the largest LID layout scheme reduced surface runoff by more than 75%.[Conclusion]LID fa-cilities demonstrate strong efficacy for short-recurrence-period storms but have limited capacity for long-recurrence-period water-logging control,particularly at severe waterlogging points.Expanding the scale of LID facilities can substantially enhance their runoff regulation capacity.关键词
