“…Over the past few years, observations of landslide terrains along the northern Black Sea coast have been successfully carried out by complementary use of data from SAR (Synthesized Aperture Radar -SAR) and GNSS (Global Navigation Satellite Systems) (Dimitriu et al, 2017;Atanasova-Zlatareva et al, 2019;Nikolov et al, 2020;Prodanov et al, 2020).…”

The territory of Bulgaria is affected by almost all dangerous geodynamic processes, such as landslides, rockfalls, erosion, debris flows, abrasion, etc. In addition, the selection of countermeasures raises the serious issue of their periodic monitoring in order to protect human life and infrastructure. The general idea of this study is to provide information about the different methods used for monitoring the above-mentioned hazardous geodynamic processes. After a comprehensive review of the available scientific developments, the author found that in the field of engineering geology, articles related to the monitoring of given processes are almost absent. The purpose of the article is to provide detailed information about the various methods of monitoring dangerous geodynamic processes and their fields of application. Due to the limitation of the article`s volume, only the main features of the utilized and available monitoring methods in Bulgaria will be presented. Hence a further, more comprehensive overview will be in a great need.

“…Характеризират се с дълбоки хлъзгателни повърхности (около 80 m), повечето от които са в условно стабилизирано състояние. В последно време отлични възможности за измервания с висока точност на Българското черноморско крайбрежие за целите на картографирането намират прилагането на безпилотните летателни системи (БЛС) (Prodanov et al, 2020).…”

The study covers a coastal slope along the northern Bulgarian Black Sea coast near Cape Kaliakra, Zelenka locality. The slope is composed of Miocene (Sarmatian), unconsolidated aragonite sediments with limestone interbeds (Topola Formation) and a steep limestone rock ridge (Karvuna Formation). Water flows along the surface of the slope, attached to the karstified and cracked limestones of the two formations. An assessment was made of the material eroded from the slope, composed of aragonite sediments of the Topola Formation, for the period from September 2018 to October 2022. The quantities of this material were measured and laboratory tests of the aragonite sediments were carried out. Their classification characteristics have been determined - grain size composition and plasticity index. Geotechnical studies and mapping of the coastal slope showed that erosion processes in the studied area represent a real geological hazard and can affect the stability of the slope, as well as the integrity of the road.
