Annotatsiya

In our study, we developed and tested a comprehensive approach to assess flood risk zones in Samarkand city by integrating data from digital elevation models of different resolutions (NASA SRTM - 30 m, ALOS PALSAR DEM- 12.5 m) and hourly precipitation data from IMERG archive. The boundaries of the urban area were obtained from the OpenStreetMap open source database. For modeling of waterlogging hydrodynamics we used HEC-RAS software package in unsteady flow mode, taking into account normal depth as a boundary condition and with a given friction slope (friction slope = 0.0125). We comparatively analyzed the results at different DEM resolutions and also took into account extreme precipitation events by filtering out the highest values from IMERG. The resulting depth and velocity maps allowed us to identify critical areas within the city limits and formulate recommendations for damage mitigation. This approach can be used as a methodological basis for further work on hydrological risk assessment and planning of measures to protect the population and infrastructure in fast-growing cities.
