MORPHODYNAMICS OF COASTAL TIDAL SUBARCTIC SEAS AFTER A STABLE TRANSITION OF AVERAGE DAILY TEMPERATURE THROUGH 0 AND COASTAL PROTECTION

It was noted that in a homogeneous coastal bluffs, the beach at comparable settings (the basic structure of the wave energy dissipation), and hydrodynamic effects (tides, surges, long waves and wind), the most intense erosion occurs in November–January. During this period, at the upper levels of the coastal profile, which are equilibrium for storm conditions with maximum tides, beach sediments are freezing and the consequent deterioration of their dissipation properties. Loss of redistribution of snow and blizzard in the profile essentially simulates morphodynamics beach properties at this time.
