Free surface flow modeling in numerical estimation of flood risk zones: a case study

Szydłowski M., Magnuszewski A.

TASK Quarterly : scientific bulletin of Academic Computer Centre in Gdansk

Vol. 11, No 4

301-313

A case study of potential inundation of Saska Kępa in Warsaw is presented. The flood is a result of a hypothetical breach of a segment of the Vistula river embankment. The inundation's evolution is simulated numerically using a model of shallow water hydrodynamics. The finite volume method is used to solve the mathematical model of the flow. Digital models of the floodplain's relief and land cover, as well as a visualization of the simulation results, are prepared using the Geographical Information System. The computations may be useful in estimations of Warsaw's flood risk zones.
