In this study, a two step approach has been applied. In the first step, in order to find the most relevant flooding areas, a one dimensional hydraulic model HEC-RAS has been used, which assumes steady state flow conditions and a discharge of Qp 1% = 7210 m3/s and Q p 0.1%= 9960 m3/s. The segment of the Vistula Valley analysed is 47.05 km long. In the second step, a smaller area has been analysed using the 2D hydraulic model of shallow water flow which is based on the Roe scheme of finite volume method.}, type={Text}, title={Two dimensional modelling of the flood zones in the Vistula River Valley in Warsaw}, URL={http://www.rcin.org.pl/igipz/Content/55503/PDF/WA51_74839_r2009-t82-no1_G-Polonica-Magnuszew.pdf}, keywords={Warsaw, Vistula river, flood zone maps, inundation modelling}, }
