There is presented a degradation case study of the Romanian shoreline belonging to the seaside of the Black Sea. The Romanian coastal Black Sea is in a continuously degradation due to the destructive action exerted by waves on the shore and, respectively, to the instability phenomena that manifest itself in the area. There are presented the influences of different causes of the degradation, the characteristics of the seaside shoreline and the interventions already made. There are done evolution foresights of the ground instability phenomena as well as shoreline degradation and recommend measures for rehabilitation. 展开更多
