The coastal beach-dune systems along the Bulgarian coast are of significant ecological import, necessitating rigorous monitoring and management. Oversight and dune management inaccuracies have been recurrently identified, particularly within the Bulgarian Black Sea coast cadastral registers. This research highlights discrepancies in depositional areas, such as Asparuhovo-Varna, Byala, Burgas-South, and Poda beach-dune systems. The coastal dunes within these regions have been systematically documented through detai...

Over 30% of the Bulgarian Black Sea shoreline is characterized as a depositional type of coast. A significant portion of it represents well-formed sandy beaches and dune fields, falling under the protection of the European ecological network NATURA 2000. The coastal sector of the Lower Kamchia Depression hosts the longest beach-dune system on the Bulgarian Black Sea coast called Kamchia-Shkorpilovtsi beach. The main task of the project "Mapping and monitoring of depositional areas along the Northern Bulgarian Blac...

The aerial imagery has a long tradition of use as a surveying method in underwater archaeology. With the recent development of new technologies, its application has become more versatile and more common. This article will present the use of aerial photogrammetry in the archaeological survey of the submerged heritage of Nessebar, ancient Mesambria, on the Bulgarian Black Sea coast. A major application is the generation of a digital bathymetric model (DBM) of the seafloor, which is reliable and accurate approximatel...

Low-altitude remote sensing technology applied with unmanned aerial vehicles (UAVs) has been recently adopted in Bulgaria. This study presents the optimal low-budget framework for a rapid high-resolution geomorphological mapping of a small part of the southern Bulgarian Black Sea coastal zone. A Quadcopter DJI Phantom 4 Pro was used to acquire the aerial images. These were post-processed using the structure-from-motion (SfM) approach. Ground control points (GCPs) surveyed with a GPS HiTarget V90 Plus were applied ...
