| Title | Application of modern technologies for flood exposure analysis - A case study of the Lower Don River basin |
| Summary | As climate change, floodplain urbanization continue to cause a greater impact on the environment, global flood risks and hazards are increasing gradually. In order to protect human and material assets, it is important to be able to efficiently analyze environmental processes and their impact on society with the help of developing information and communication technological achievements. Modern remote sensing, geospatial information system and hydraulic modeling technologies provide an opportunity to examine in detail the exposure of a given area to floods. Built up areas are the most vulnerable from land use categories in terms of human life and property value, so the protection of these areas is of key importance. The precise capabilities and use of the mentioned information and communication technologies in the field of exposure assessment of built up areas were presented through the case study of the Lower Don River located in Russia. The amount of water flowing down the river is currently regulated by the Tsimlyansk Dam, which will reach the end of its design life span in the decade of 2020, thereby further increasing the significant flood risk in the downstream region. In this study, the effect of 4 possible flooding scenarios was modeled. Of these, 1. showed the effects of the largest water discharge ever measured on the Don River, and 3 indicated the effects of a possible dam failure on the floodplain. Based on the modeling results, it could be said that the flood exposure of built up areas in many nearby settlements is extreme in terms of water depth. This thesis could be used for multiple purposes. On one hand the methodology described in the study could also be applied in other water systems to investigate flood exposure. On the other hand the results of the case study could be decisive for the bodies responsible for local flood protection and urban development. |
