Abstract. Results of flood modelling for three cities located in different parts of Russia: (1) Veliky Ustyug at the Northern Dvina river (Europe); (2) Mezhdurechensk at the Tom river (Siberia); and (3) Blagoveschensk at the Amur river (Far East) are presented. The two-dimensional hydrodynamic model of flow in channels and on floodplain STREAM_2D on the basis of the numerical solution of two-dimensional Saint–Venant equations on a hybrid curvilinear quadrangular and rectangular mesh was used for the simulations. Verification of the model through a comparison of simulated inundated areas with outlines of flooded zones from satellite images for known hydrologic situations demonstrate close correspondence (relative errors of 7–12% in terms of the area for peaks of the analysed floods). Analyses of embankment influence of large-scale levees on the water flow demonstrate that, in some cases, water levels could rise by more than 1 m and the patterns of the flooding zones could significantly differ.

Short summary
Results of flood modelling for three cities located in different parts of Russia: Veliky Ustyug (the Northern Dvina river); Mezhdurechensk (the Tom river) and Blagoveschensk (the Amur river) are presented. The two-dimensional hydrodynamic model STREAM_2D was used. Additional verification of the model through comparison of simulated and received from satellite images flooding zones was carried out. Analyses of embankment influence on the water flow were performed.
