Hydrological Effect of Impermeable U-shape Bioretention System
Translated Abstract
An impermeable U-shape bioretention system was built in Chongqing University of Arts and Sciences,whose hydrological effect was monitored during 2016 and 2017 with rooftop runoff as inflow water.The results indicated that the system was capable of reducing the peak runoff rate and the total runoff volume,delaying the peak flow and prolonging the release of saturated water.The values of Rp,Rv,Rt and Rd were 0.19 ±0.09,0.58 ±-0.14,1.83 ± 1.57 and 2.75 ± 2.81,respectively.The probability of rainfall event without outflow was only 4％,and the fitting results indicated that there was no outflow when rainfall volume was below 0.34 mm or rainfall intensity was lower than 0.054 mm/h.
