| Abstract |
In this study a hybrid design scheme for the purpose of designing infiltration-based retentions and a detention is applied to reproduce urban hydrologic regime to natural hydrologic regime. The proposed method is based on the NRCS-CN storm water estimation technique, and applied to determine the size for storm water control facilities on the Oncheon stream as an example. Urban area, corresponding to less than 70 m height of the Oncheon stream basin area is targeted. The results indicate that the proposed scheme is very useful to reproduce its undeveloped flow-duration curve. |
