Methods used for monitoring geodynamic processes on the territory of Bulgaria

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.
