Abstract. The paper discusses the problem of determining the boundaries of flooding zones, flooding of territories. The paper describes technique for constructing cadastral maps of flooded zones for various values of the estimated availability of water levels, which is based on hydrodynamic and geoinformation modeling. For creating digital elevation models (DEM) of the conformation, we use spatial data obtained from a large number of sources. We applied the described technique to construct cadastral maps for a number of settlements in the Volgograd region of the Russian Federation. As a result, we get a set of xml-files prepared for registration with the Federal Agency for State Registration, Cadastre and Cartography. For the Republic of Belarus, the problem of flooding the territories is also urgent. The floodplain areas of the Pripyat River are most prone to flooding. We built a DEM for the area in the vicinity of Petrikov city and carried out hydrodynamic modeling. As a result, the inundation maps were obtained. The method proposed in this work is based on a mathematical model of shallow water in a single-layer approximation. This model is successfully applied in simulation of flooding for territories by flood waters. Solving the problem of determining the boundaries of flooding zones requires a transition to a two-layer shallow water model that takes into account the interaction of surface and ground waters.
Key words: cadastral map, numerical simulation, flood zones, digital elevation model, shallow water model.
