Abstract: Urban drainage systems can be divided into two networks, the surface network which mainly includes streets and open channels, and the subsurface network which is mainly the sewer system. If the hydrograph generated by the rainfall does not exceed the sewer capacity the flow is drained by the downstream sewer system. However, when the sewer system is not capable to divert the incoming hydrograph to proper outlets, the sewer system can become surcharged and flooding will occur. In this study, a new linking element between surface and subsurface network is presented. The surface-subsurface connections including their subcomponents are analysed individually before assembly into the multiple-linking-elements. The Multiple-Linking-Element is implemented on SIPSON 1D/1D model. Theoretical results and hypothesis are presented. A methodology for a real case application is shown.
