Abstract

For the prevention of urban flooding and control of non-point pollution, exfiltration from infiltration facilities is quite important. However, the analyses of the performance of exfiltration from the infiltration facilities spread over the real catchment is still in require. The present study simulated the variations in the exfiltration volume and rate at manhole bottoms by changing rainfall patterns. Giving a exfiltration coefficient by extrapolating the saturated hydraulic conductivity at the surrounding natural base soil, the performance of exfiltration was predicted realistically.
