Zoning of the north-eastern part of Ufa according to the development of hazardous geological processes

The article is focused on consideration of the engineering geological conditions of the area situated in the north-eastern residential part of the Ufa city (the capital of Bashkortostan). The majority of urban population lives in the Ufa-Belsko-Shugurovsky interfluve area. Exogenous hazardous geological processes are extensively developed there. The most wide-spread are karst, karst-suffusion, slope and erosion, as well as other engineering geological processes, which are manifested in the relief by sinkholes, craters, landslides, ravines and washouts. The research was based on a set of schematic maps compiled in 2013 according to archive data for the development of the Ufa master plan on a scale of 1:10000, as well as the updated versions of these maps [3]. The maps were created considering the state of the most problematic areas of geohazard activation. The occurrence of these processes was previously investigated by satellite and aerial images, and also in field by route survey as a part of reconnaissance. Archival geological information from the mining documentation was also used when compiling the maps. Engineering geological research and zoning territories with manifestation of karst, karst-suffusion, slope and other hazardous geological processes is proved to be relevant for the design of buildings and engineering structures. Currently, the engineering geological background data on the Ufa city territory is quite plentiful, and yet it remains uneven in the study area.
