Abstract
The studied sea coast settle down between Berezansky strait and Ochakovskiy Cape with long is 16 km. The coast represented the abrasion site (active clayey cliff) and the accumulative site (the sandy Lagernaya spit). In nature the cliff height is about 25 m, and average rate of abrasion cliff retreat 2.5 m/year. The Lagernaya spit has length about 6 km, height to 2 m and width to 150-200 m. It is linked with active cliff and displaced towards liman. Nowadays Lagernaya spit is in a degradation stage by impact of anthropogenous factor. Beaches are disappear gradually. The coast is built strongly up. The submarine slope is shallow up to 0.001-0.005. As a result, the wave factor is low, and at the same time impact of storm-surges is heightened. Artificial relief forms wide distributed as a hydrotechnical constructions that are sea-walls, jetties, moorings, and bearms, groins, sea-port dippers, navigate canals too located. All of them are blocking abrasive sources of shore sediments in coastal zone, and its are aggravating the sediment deficit and increase destructive tendencies of nature evolution. Around of Kinburn Strait typical is relative the sea level rise. During past 15 years the average rise value is up to 9,8 mm/year, and as a result this process lead to submerging of Lagernaya Spit, Ochakovskiy Cape terrace and Kinburn Peninsula. Also, rising of underground water, activization of landslides, salting waters in Dnepr and Southern Bug mouths, reinforcement of stormy waves development take place in investigated coastal region.
