SWMM-LID 모델을 이용한 토지주택연구원의 물순환 개선효과 평가 = Evaluation of Water Cycle Improvement in LH Institute Using SWMM-LID Model

다국어 초록 (Multilingual Abstract)

SWMM-LID was calibrated with flow monitoring data in LHI to evaluate runoff after LID application. The flow rate in the B basin was estimated to be 0.94 and 6.15 for O/S and Dv, respectively. In the A and C basins, the difference between the observed and simulated data was greater than in the B basin. As a result of runoff reduction efficiency by the application of LID facilities, the change of infiltration increased from 34.6% to 45.8% in the entire watershed, and the runoff decreased from 58.8% to 46.3%. In the runoff reduction of each LID facility, rain garden E showed the highest effect with 99.9% and bioretention B showed the lowest effect with 27.5%. In order to evaluate the efficiency of each LID facility, a comparison is made between the pore volume (V) of the LID and the catchment area (A). The runoff showed a runoff reduction effect of about 70% above the 0.1 volume/area (V/A) value. As a result of examining the runoff reduction with LID facilities by the LID module of SWMM, a reasonable design is possible by reflecting the appropriate LID volume to drainage area.
