Abstract: This paper deals with the development on a numerical simulation method of the hydraulic transient induced by overland flood flow intrusion into underground space in an urban area. In particular, hydraulic transients such as the surge and the undular bore in the underground space are investigated experimentally and numerically. The numerical model used here can reproduce the hydraulic transient with the propagation of an interface between open channel free surface flow and pressurized pipe flow. The calculations are carried out under the experimental conditions of laboratory tests. The numerical results are compared with the laboratory tests to make sure the validity of the model.
