| Title | Assessing flood risk for urban areas in the Lower Don River using GIS and Remote Sensing |
| Summary | Frequency of reported severe flood events and associated economic loss has been rapidly increasing in recent years. This trend might be explained by the combination of such factors as climate change and the expansion of urbanized areas into floodplains. The aim of this research is to explore the scale and consequences of floodplain urbanization of the Lower Don River (Rostov Oblast, Russia) and assess related flood damage threats. The environmental security of this area is a matter of great importance, since historically flood events were common for the region and even after the construction of the Tsimlyansk Dam and regulation of the water discharge, the risk of inundation still exist. The combination of various techniques was used in order to address the research questions: historical data collection, application of the Remote Sensing, GIS, hydrological modeling (FLO-2D). It was found that some rate of the urban growth is inherent in the study area. The simulations of the five flood events were conducted. The differences in flood hazard depending on the water discharge were analyzed. The most hazardous areas within the floodplain were defined, by the maximum flow depth and the maximum flow velocity. It was found that generally small villages on the river bank within the wide parts of the floodplain will experience the most intense flood, together with the territory right under the Tsimlyansk Dam. The results acquired through this research might be interesting for various stakeholders - researchers, urban planners, local population. |
