Modeling of mesoscale circulation and oil pollution spreading in the Georgian coastal area of the Black Sea under real atmospheric forcing
No full textThe paper presents some results of numerical experiments on modeling mesoscale circulation and oil spill propagation in the coastal zone of Georgia and adjacent waters. Calculations of circulation and thermohaline fields are performed using a regional numerical model of the Black Sea dynamics based on solving the full system of ocean hydrothermodynamics equations using the method of splitting into physical processes, coordinate planes and lines. A 2-D advection–diffusion equation of impurity is applied to simulate and forecast oil slick transport. Numerical experiments conducted under conditions of real non-stationary atmospheric forcing with a horizontal resolution of 1km have shown that circulation in the southeastern region is characterized by the generation of cyclonic and anticyclonic eddies with diameters from about 5-8 km to 200 km. Mesoscale eddies make a significant contribution to the spread of oil pollution
Reconnaissance archaeogeoradiolocation study of the territory of the Ninotsminda monastery complex
No full textGeorgia, Kakheti, Sagarejo, Ninotsminda Monastery Complex. Ninotsminda Cathedral is a notable monument dating back to the 6th century. It was built on an old idol site [1, 2] during the time of Saint Nino. Within the framework of the Ninotsminda Complex Geophysical Expedition, archaeogeoradiolocation work was carried out using the Zond-12e georadar, 500MHz screened and 150MHz dipole staff antennas [3, 4, 5, 6]. Georadiolocation data were collected, processed and interpreted using the Prizm 6 staff software. Georadiolocation profiles/GPR-sections were conducted in the inner courtyard of the monastery and on the territory of the monastery itself. This paper presents the results GPR-section obtained and interpreted by the 500 MHz antenna conducted in the inner courtyard of the monastery complex
Numerical modeling of Kutaisi city atmospheric air pollution with PM2.5 particles in winter during calm
No full textPropagation of PM2.5 particles discharged by the motor transport in Kutaisi city air in winter under background calm meteorological conditions has been numerically simulated through combined integration of 3D model of meso-scale atmospheric processes in Caucasus and equation of atmospheric propagation of passive polluting admixtures. It has been shown that ground-level concentrations reach high figures twice a day – at 7-9 h in the morning (7-9AM) and 20-21 h in the evening (8-9PM). It has been obtained that the process of aerosol propagation depends on orography of dynamic fields, territory and thermal regime of underlying surfac

Using Seismic Survey Methods to Solve Engineering (Hydrotechnical) Problems
No full textThe development of hydroelectric construction has necessitated a comprehensive study of the rock masses forming the foundations of hydraulic structures. This issue becomes particularly relevant in the case of high dams, which are often accompanied by large reservoirs and are frequently located in areas of high seismic activity. The paper focuses on the role of engineering geophysics—specifically, seismics—in the construction of major structures. As an example, we present a specific project and the methods used for its implementation, namely the studies conducted by the Institute of Geophysics in the design area of the Nenskra Hydropower Plant
Drought Periods Assessment in Eastern Georgia Using SPI-3 Index in 1936-2023
No full textIn the work detailed statistical analysis of the duration of drought periods D (months) normalized per decade for four SPI-3 categories (agriculture drought; SPI ≤ -1.0, ≤ -1.5, ≤ -2.0 and ≤ -2.5) in Eastern Georgia based on observations at 18 meteorological stations during 1936-2023 is presented. The statistical characteristics of D values in 1936-2023, 1936-1975, and 1984-2023 were compared. The variability of D values in 1984-2023 compared to 1936-1975 (ΔD) was assessed. In particular, it was found that ΔD values are different at different points. On average, for eastern Georgia, ΔD values for all SPI categories, except ≤ -2.5, are increasing (i.e., an increase in the duration of droughts is observed)
The Turn Towards Geophysics in Historic Research and the Chances it Offers for the Study of Weather Modification in Georgia
No full textThis paper aims to inform the participants of the conference „Modern problems in Geophysics” about ongoing historic research on Geophysics and thereby enable interdisciplinary exchange. First, it is given an overview of selected scientific literature from fields such as the history of science and knowledge, environmental history and Cold War history. This literature illustrates the significantly grown interest in the history of Geophysics, in quantity and diversity alike. Then, drawing on the example of weather modification, the opportunity for such a history of Geophysics in Georgia is outlined from a historical perspective
Technogenic landscape - as Paradynamic Systems Determining the Ecological Condition of mining impact Zones
No full textThe present work concerns some landscape-geochemical peculiarities of Georgia. The exploitation of the fields has caused chemism modification of the environment. The dependence of the linear process of biologic recultivation on physiographic factors is obtained by means of multifactor regression analysis and the ways of effective optimization of the mining region environment, damaged under the influence of technogenesis, are distinguished. The influence of anthropogenic factors is spread even on the territories outside the field exploitation area (approximately twice exceeding its area) and causes regime changes of soil waters and migration of chemical elements, activation of erosive processes, falling of ground efficiency, etc. Besides the coefficient of every single opening roof layer (Tchiatura) i.e. Bever coefficient has been calculated and the optimum admissible parity has been determined that excludes the possibility of annual erosion.
Theoretical and practical results of the research can be successfully applied in forecasting technogenic processes and in the field of solving environment optimization problems
Seasonal Variability of Air Infiltration Rates in Buildings with Differing Airtightness
No full textThis study investigates the seasonal variability of air infiltration rates (Ninf) in two residential buildings with differing envelope airtightness (B1: older, lower; B2: newer, higher). Ninf were quantified using the CO2 decay method in February and June 2025. Ninf were higher and more variable (B1: 0.14–0.27 h─1, avg 0.19 h─1; B2: 0.04–0.21 h─1, avg 0.10 h─1) in winter and lower (B1: 0.06–0.25 h─1, avg 0.13 h─1; B2: 0.00–0.22 h─1, avg 0.06 h─1) in summer. Ninf decreased with increasing outdoor temperature, with meteorological influences more evident in the less airtight building
