Abstract EN
Hydrodynamic models were commonly used for flood risk management in urban area.
This paper presents initial efforts in developing an urban flood inundation model by coupling a one-dimensional (1D) model with a two-dimensional (2D) model to overcome the drawbacks of each individual modelling approach, and an additional module is used to simulate the rainfall-runoff process in study areas.
For the 1D model, the finite difference method is used to discretize the Saint-Venant equations.
An implicit dual time-stepping method (DTS) is then applied to a 2D finite volume model for an inundation simulation to improve computational efficiency.
A total of four test cases are applied to validate the proposed model; its performance is demonstrated by a comparison with an explicit scheme and previously published results (an extensive physical experiment benchmark case, a vertical linking example, and two real drainage cases with actual topography).
Results demonstrate that the proposed model is accurate and efficient in simulating urban floods for practical applications.
