Geographical and Hydrological Assessment of Floods in the Russian Black Sea Region

The regional spatial-temporal analysis of the formation of the maximum flow was made on the basis of geographical and hydrological method using GIS-technologies and statistical methods. The characteristics of natural and anthropogenic prerequisites for the formation of floods were performed. Conclusion about the leading role of natural factors in the formation of floods, especially extremely high rainfall, which have become more frequent in recent decades, was made. The features of spatial-temporal variability of maximum water levels were shown. Simulation of flood zones was performed using a geographic information system and digital elevation models. Calculated water levels were set by long-term observation series and in their absence by high water marks. The extreme floods were reconstructed in some settlements, some recommendations to reduce potential damage as they pass in the future were provided.
