Two-dimensional hydrodynamic flood modelling for populated valley areas of Russian rivers
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 fl...

| Summary: | 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. |
