ON SEA WAVES' PROPERTIES MEASURED IN BURGAS BAY TRANSITIONAL WATERS, BLACK SEA.

The study presents results and discuss statistical properties of wind-generated sea waves measured in transitional waters of the Burgas Bay at the Bulgarian Black Sea. Wave measurements were acquired by Acoustic Doppler Current Profiler at two locations offshore Kraymorie and Chernomorets at water depths of approx. 15 m and 18 m, respectively. At each location, data were recorded for about three and a half months in winter seasons of 2021-2022 in front of Chernomorets and in 2022-2023 offshore Kraymorie, when storm activity intensifies posing higher risk of flooding, erosion and the threat to human activities along the coast. The study examines in statistical terms variability of significant wave height, peak wave period, mean wave direction and their interdependence. It also explores the storm activity during both periods of data collection in terms of wave height, storm duration and direction. Analysis includes clustering wave parameters as joint frequency of occurrence as percentage across predefined intervals to reveal their distribution in the time-span of measurements.
