Description parameter
The extent of hydrographical changes for the assessment period 1983-2017 is 6.947 square kilometers, which is 0.811% of the MRU’s total area. In 2012-2017 the changes extend to 0.538 square kilometers, interpreted as a notable increase in the permanent alteration of hydrographical conditions.
Adverse effects by hydrographical conditions alteration were estimated over 0.131 square km of infralittoral sands that correspond to 0.17 % of the total habitat extent in the MRU. The outcomes contribute to the assessment of the extent of overall adverse effects under D6C5.

Description criteria
The marine unit is characterized by a very high degree of technogenic pressure due to construction of various types of coastal structures. For the period 1983-2017 changes in the hydrographical conditions are assessed only in the nearshore, as their combined total area comprises 0.811% of the MRU’s total area, while in 2012-2017 the changes extend to 0.538 square kilometers. This marine unit is determined to be subjected to the largest permanent alterations of hydrographical conditions along the Bulgarian Black Sea coast.

In compliance with Directive 2017/845/ЕC and Decision 2017/848/ЕU the changes in hydrographical conditions were assessed based on comparison of pressures on the marine environment estimated for a selected reference period (reflecting the earliest available shore state unaffected by human interference) with that of the reporting period 2012-2017. As a reference year was adopted 1983, while evaluation periods are 1983-2017 and 2012-2017.

Description criteria
The Marine Reporting Unit is characterized by a low degree of technogenic pressure due to construction of various coastal structures. There are no hydrographical changes during 2012-2017, while in 1983-2017 the changes are assessed only in the nearshore, as their combined total area comprises 0.011% of the MRU’s total area. In comparison to other marine reporting units along the Bulgarian Black Sea coast, this is the unit with the second smallest changes in the hydrographical conditions.
