Although the numerical analysis is one of the most effective tools to evaluate the existing urban drainage networks, the scale of calculation might be a trouble for analysis of large-scale networks. Therefore main pipe analysis by modeling outflow from sub pipe is generally applied. But sub pipe analysis is necessary to evaluate urban drainage networks because the water level of main pipes doesn'trepresent that of sub pipe areas in some cases. In this report a new method forsimulation of large-scale networks including sub pipe analysis are proposed. The procedure consists of two stages. The first is the process of main pipe analysiswith modeling sub pipe areas as simple tanks. The second is the process of sub pipe analysis with the main water levels as boundary conditions.
