Abstract

Abstract

A new residential district developed via low impact development (LID) was selected as the research project, the multi-target control effect of total runoff volume and peak flow rate was achieved. The method of comparative analysis under the same rainfall event was adopt, six monitoring sites were selected at each outlet (A to F) in the LID residential district, and an outlet (G) from traditional residential district was selected as the comparison monitoring site, which had similar underlying surface types with the LID residential district. The monitoring results via seven typical rainfall events showed that: compared with traditional residential district, the LID residential district's runoff discharge total volume was decreased by 12.1%~100%, while the pollutant reduction rate was 69.6%~100% and the peak flow reduction rate was 12.3%~100%. By continuous modeling of typical annual rainfall data, the results showed that reduction rate of total runoff discharge volume was 77.3%, and that of pollutants was 66.4%. Therefore, both monitoring and modeling results indicated that the LID residential district could effectively control the total discharge of runoff and pollution load. The above research results could provide technical support for the development of sponge-residential district.
