The use of digital twin models in immovable culture heritage enables better decisionmaking about preventive maintenance, heritage management, and interpretation, as well as accurate digital documentation. This publication discusses an approach for creating a digital twin using different methods of spatial data acquisition: close range terrestrial digital photogrammetry, aerial digital photogrammetry and terrestrial laser scanning. The "Holy Transfiguration" Church in Pomorie, Bulgaria which is the oldest functioni...

In recent years GNSS studies play an increasing role in studding of natural risk hazards and active tectonics. The area of Sofia is part of the broad South-Balkan Extensional Tectonic System. This highly populated area of economic significance, even showing to be not so active as other parts of the System is also affected by natural hazards, as active seismicity, landslides, rock falls, debris, etc. GNSS studies are extremely important for understanding of natural hazards and recent geodynamics of the area, especi...

The monitoring of geodynamic processes with modern GNSS technology in the area of Sofia and Southwest Bulgaria has been going on for more than 25 years. To investigate modern crustal motions in the area, GNSS data obtained between 1996 and 2022 are analyzed to obtain the velocity field for southwestern Bulgaria. Every year, measurements are carried out on a part of the points, and the last measurements were carried out in 2022. For the entire period, monitoring covered 28 stations. To evaluate the new result for t...

The purpose of this study is the analysis of the dynamics of tectonic movements accompanied by two strong seismic events that occurred in the Durres area (Albania) in September-November 2019, through the use of GNSS technology, applied to national permanent satellite geodetic networks. Previous studies have been carried out on our study area by foreign authors from Croatia, Greece, and Italy. For our study case, we relied on geodetic weekly data secured from the Bulletins of Italian and Austrian stations, BSW52, o...

In this study, we aim to demonstrate the change in the topography of the sea floor as a result of the sedimentation of rivers. The study area is the Divjaka Bay, bounded to the north by the delta of the Shkumbin River and to the south by the delta of the Seman River, on the Adriatic coast of Albania. The method used is the Integrated Satellite Bathymetric Surveying method. The monitoring period extends from 2017 to 2020, based on 4 monitoring campaigns. The longitudinal bathymetric profile extends northsouth, in p...

The field of construction is currently one of the most stable and active fields of activity. It presents complex activities that are done in phase and chronologically until the end of completion execution stage. Realization of the foundation or its characteristic elements it includes a number of preparatory activities such as: land preparation and release of various tasks, shoveling and ground consolidation. The type of consolidation it is chosen according to the depth of the escape and It is about choosing a supp...
