Abstract
In this study, the hydraulic model test was performed for the 3 vertical inlets of the Shinwol rainwater storage & drainage system that Seoul City plans to install, and the control discharge value actually measured was analyzed comparing to the value obtained using the theoretical control discharge equation suggested by Yu and Lee (2009). In the results, it was 66~69% compared to the value obtained from theoretical equation showing that the control discharge value according to the theoretical equation is calculated excessively. The sensitivity analysis by design factor was performed using 3 models conducted in this study and 15 hydraulic experiment models conducted in existing research Yu and Lee (2009). The sensitivity analysis of control discharge equation was performed by dividing $Q_{cm}/Q_{cp}$ into 3 ranges. The suggested equation considered only the influence on the tangential intake structure design factor B, z, ${\beta}$, e/B, so ${\theta}$, L considered complex influence suggested equation needed to be more improved.
