The Specific Features of Modern Dynamics and Coast Structure of the Black Sea Within Romaniaby Yu. D. Shuisky, Univ of Odessa, Odessa, Ukraine,
Abstract: The Romanian Black Sea coasts are studied inadequately in comparison with Ukrainian, Russian, Georgian, and Bulgarian coasts. Abundant data have been collected in the Danube delta. The total length of Romanian Black Sea coast from Mosura bay to the area north of Sivriburun Cape is 246 km or 5.6 % of the entire coast. Romanian coasts are subdivided into two sections. The first incorporates deltaic coast. The total area of the delta is 5640 sq. km, 4400 sq. km or 78% of which belong to Romania. The shoreline length is 145 km, or 59%. Most deltaic coasts are retreating. Coast is accreting mostly near the Sulina and Gheorghe river mouths. Maximal rate of accretion is 8 m/y, retreat rate being 7 m/y. Another section of Romanian coast lies to the South of Buhaza river mouth (Vadu). Its length is 101 km (41%). Active cliffs (2 to 40 m high) composed of Anthropogene and neogene loess, clay, and limestone are located here. Average abrasion rates are 1-2 m/y, maximal rates being 7 m/y. Accumulative forms are represented by lake barriers. These barriers, as well as beaches are composed of sand. In contrast to the northern coast, Southern Romanian coast is subject to intensive anthropogenic impact.
