| In this paper, the sub-soil storage system for utilizing urban instream flow of rainfall runoff was developed and examined through experiments. The artificial rainfall facility and sub-soil storage were installed in the experimental area. The effect of the water qualify improvement and the storage effect were analyzed through the several experiments. Through the experiments of rainfall intensity variation, which are the rainfall intensity of 20mm/hr, 30mm/hr, 40mm/hr, 50mm/hr was indicated SS concentration can be reduction until 68£¥. Also, the ration of the storage volume is varied from 42.8£¥¡79.9£¥ based on the rainfall intensity. The reduction rate of the BOD, CO $D_{Mn}$, SS, T-N, T-P was 30£¥, 42£¥, 68£¥, 39£¥, 26£¥. As the result, water quality of runoff and efficient of runoff reduction by the system are much improved. The rainfall runoff with the installation of sub-soil storage could be used for instream flow.. |
