Human Impact and Rates of Shore Retreat Along the Black Sea Coast

Yuri D. Shuisky, Maurice L. Schwartz

Abstract


The coast of the Black Sea is 4431 km in length, 47% of which is actively eroding. Much of the coast consists of cliffs, divided into three types: rockfall, landslide, denudation. Cliff erosion rates, for these types are: 0.3-0.5 m/yr to 4-5 m/yr; 0.1-0.3 to 2-3 m/yr; and 0.01 to 0.2 m/yr, respectively. Beach sediment available is: 5-7 m3/m/yr in the Odessa region; 5-6 m3/m/yr in the Western Crimea; and 3-6 m3/m/yr on the Rumanian and Bulgarian coasts. Human impact has greatly accelerated erosion rates at many coastal sites; and there has been a policy change, from engineered structures to artificial nourishment, in dealing with this problem.
