The paper presents long-term dynamic of the Anapa bay-bar submerge slope. The Anapa bay-bar submerge slope contains five morphological elements Solenoe Lake, Bugazskaya bay-bar, Blagoveshchensky butte, Vityazevskaya bay-bar, section from Vityazevo to Anapa. The erosion-accumulation sites change from year to year. In general, from 2012 to 2018 the amount of sediments on the Anapa bay-bar submerge slope decreased by 1.89 million m3. On the sites Solenoe lake and Blagoveshchensky butte from 2012 to 2018 accumulation are 0.20 and 0.14 million m3, respectively. On the sites Bugazskaya and Vityazevskaya bay-bars from 2012 to 2018 erosion are 0.52 and 0.64 million m3, respectively. On the section from Vityazevo to Anapa from 2013 to 2018 erosion is 1.08 million m3. The greatest changes in the underwater relief occur in a 600-meter coastal area to a depth of 67 m. The underwater bars are formed and moved just in this area.
