Coupled Urban Areas Inundation Model with Interaction Between Storm Water System and Surface Flow - Case Study of Sea Level Impact on Seaside Areas Flooding
Abstrakt
Inundations are becoming more frequent than ever. What is connected with increasing area of impervious surface in cities. This makes predicting urban flooding and its scale especially important. At the seaside we observe additional conditions such as sea level that makes accurate numerical modelling of issue even harder. With complex approach to the matter which is simultaneous calculation of storm water conduit flow and overland flow we can improve obtained results. In this paper we will present coupled model for urban flooding modelling which consist of three components: 1D storm sewage flow, 1D surface flow and interaction between models. Pipe flow will be calculated by solving The Saint-Venant equations using finite difference method (FDM) explicit TVD-McCormack scheme. Which is the modified version of classic McCormack scheme that can be used to capture sharp discontinuities moving along the sewage. Whereas the overland flow will be described by solving 1D nonlinear diffusive wave equation with modified finite element method.
