Abstract. The method of creating cadastral maps for flood areas with special conditions of use based on geoinformation and hydrodynamic modeling is described. This approach is used primarily for settlements located in river valleys. The hardware and software complex “EcoGIS-2D-Simulation” is used to conduct simulation experiments to study the dynamics of surface waters in a specific area in the vicinity of a river system. The computational module uses the Combined Smooth Particle Hydrodynamics — Total Variation Diminishing numerical algorithm for parallel integration of shallow water equations on GPUs with CUDA technology. The module for building a digital model of hydrological landscapes is an important component. This module includes a digital elevation model and sets of parameters that determine the hydrological resistance to river flow. The boundaries of the flood areas for some settlements of the Volgograd region at different values of flood probability are constructed.

Key words: numerical modeling, flood areas, cadastral maps, geoinformatiсs, GIS-technologies.
