|Geomorphology and lithidonamics of submarine canyons as an engineering geological factor of hydrocarbon resources development (the Russian Black Sea sector)|
|Geomorphological and lithodynamic features of submarine canyons are considered on the example of the Black Sea canyons of Shahе and Mzymta. Sonar, echo-sounding, seismic acoustic profiling, underwater video surveillance and bottom sampling were used. Presents information about the structure, size and speed of advancement of the head parts of the canyons. Along the longitudinal profile of the canyons, the main geomorphological areas are distinguished — landslide domain (convex/linear), entrenched canyon (concave), channel levees, as well as adjacent areas deep sea fans and apron of sediment transport. It is shown that the selected areas have an individual character of lithodynamic processes and the development of dangerous geological processes, have their own features of the structure and composition of the upper part of the section of bottom sediments.
The data and parameters of canyons define them as an important engineering and geological factor that requires a careful considering when designing petroleum engineering instalations on the seabed.
Keywords: submarine canyon, geomorphological area, lithodynamic processes, Black Sea.
