西安市雨水花园蓄渗雨水径流的试验研究
Experimental Study on Infiltrating Stormwater Runoff with Rain Garden in Xi'an,China
摘要
Abstract
Rain gardens are bioretention systems that are designed with urban landscaping and used for retaining and purifying urban stormwater runoff.Rain gardens can mitigate the adverse impact of urbanization on hydrology and water quality.This paper presented an experimental study on the infiltration capability of a rain garden constructed in Xi'an,China.Time and volume for overflow in the rain garden under storms of variable duration and recurrence interval were calculated.The results showed that the loess soil in Xi'an area had a good infiltration capacity,the average value of the measured infiltration rates was 2.346 m/d in the rain garden,nearly all stormwater runoff collected in the relatively wet year of 2011 infiltrated and recharged to the groundwater.For storms of a specified recurrence interval,rainfall intensity and the duration were two controlling factors that caused overflow in the rain garden.关键词
