Siphonic rainwater systems enhance the protection afforded to large buildings while offering improved, and more sophisticated, design solutions. Current interest is driven by the level of investment in system installations and the consequence of system failure - a single failure can result in damage claims of millions of pounds.The proposed research will further develop an existing unsteady flow model that simulates the flow regimes simultaneously present within a simple siphonic drainage system, from initial free surface flow as the storm develops, through a two phase flow stage, while air entertained or initially present in the system is flushed out, until the flow design condition is reached, via the method of characteristics finite difference technique. The enhanced simulation will simulate multi-outlet systems - pipe networks collecting from several roof or gutter outlets, where one or more allows the ingress of air due to a local fall in gutter water levels - causing the re-pressurisation of the system, failure of the siphonic action and transient propagation. It is intended to review and model the modes of connection commonly used between the system and the underground sewer. Data will be collected both in the laboratory and at two comprehensively instrumented field sites.
