| Research Abstract |
In this study, an experimental setup of urban area with a sewer pipe and a rainfall supplier is prepared in order to reproduce urban inundation due to heavy rainfall, which is occurring frequently. Using this setup, experimental results are compared with simulation results of a numerical model. Consequently, the flow discharge between the ground surface and sewerage system is overestimated by the conventional interaction model using the step-down formula and overflow formula. Though corrected values of parameters of those equations are proposed as an alternative method, further consideration will be necessary in the future, including revision of the shape of the equation itself.
