Relief-Forming Role of the Ice Factor in the Coastal Area of the North-West Part of the Black Sea

Purpose. To define the role of ice factor in morpholithodynamics coastal area North-West part Black Sea. Methods. Field and in-office research was carried out Sea during winter seasons 2005-2019. The work included geometrical leveling beach surface shore-fast ice, drilling layer, depth sounding, sampling deposits an core. content determined by weighting them after melting evaporating a known volume Results. Formation hummock ride-ups, freezing accumulative forms, congelation fast with bottom, into thrown on formation meltwater runoff channels, melted deposit banks, melt holes had been observed. Shore-fast Odesa Bay 1.0 to 1.6 meters thick. Hummocks 0.8 2.3 high were formed. average 15.7 g/m2 111.5 g/m2. Within protected water coast protection complex, thickness 0.5 m. Repeated measurements revealed temporary accumulation at depths 1.5 2.0 m distance 30-40 from edge. within 186.5 beaches open shore 0.2-0.5 Banks sand gravel-pebble between 0.4-0.8 1 1.2-1.4 m3/m formed frozen onshore flow storm overwash. Conclusions. In Sea, impact is characterized rhythmic observation severe, moderate warm winter. Generally, it hasn’t significant impact. somelocal points cold may results alteration relief deposits, causes damage hydraulic structures. Ice gets saturated mostly when submerging bottom ebbing, contacting beach, being directly onto its along cracks, aeolian movement. For artificial defined peculiarities hydrodynamics these sections. shapes relief, under factor, are minor; they exist for duration impact, disappear ends.
