RADIOECOLOGICAL MONITORING OF SOILS IN KVEMO KARTLI, GEORGIA

(STEF92 Technology, 2025-08-15, Sophiko Matiashvili, Lia Matchavariani, Zaur Chankcseliani)

Show more

This study evaluates the radioecological condition of soils in the vicinity of major industrial enterprises in Georgia, focusing on contamination by radionuclides (K-40, Cs-137, Sr-90) and heavy metals. Three key industrial regions: Rustavi (metallurgical and chemical industries), Bolnisi (polymetallic mining), and Gardabani (energy production) were selected as research sites. Spectrometric analysis was performed using the Atomtex Plasma Atomic Emission Spectrometer (ICPE-9820) in compliance with GOST standards. T...

A COMPARATIVE STUDY OF CARBON SEQUESTRATION IN DIFFERENT TYPES OF FOREST

(STEF92 Technology, 2024-11-01, Nodar Khujadze, Lia Matchavarian)

Show more

This study aimed to investigate carbon storage dynamics in pure pine, oak, and mixed forests within a one-hectare area. Tree samples were collected to measure their weight, size, and density. Each type of forest was estimated how much carbon is hold per hectare. The findings revealed significant differences in carbon storage capacities among them. Pure oak forests emerged as the top carbon reservoirs, with 57% of their trees' mass comprising carbon. Pure pine forests followed closely with 51% carbon storage. Inter...

POSITIVE AND NEGATIVE ASPECTS OF WATER RESERVOIRS

(STEF92 Technology, 2022-11-15, Lia Matchavariani, Giorgi Metreveli, Zaza Gulashvili)

Show more

The main purpose of the research was to create a comprehensive methodology to assess, predict and prevent the consequences of the negative impact of water-reservoirs on the environment, provide the safety of population and infrastructure; to find a way allowing jointly realize the interests of hydropower and coast protection. To achieve this goal, the following methods were used: full-scale experiment, field-expedition surveys on operating reservoirs, informational analysis, mathematical methods of least squares, ...

ROLE OF WATER RESERVOIRS IN THE SEASHORE DYNAMICS

(STEF92 Technology, 2021-12-20, Lia Matchavariani, Giorgi Metreveli, Zaza Gulashvili)

Show more

Construction of water-reservoirs across the rivers flowing into the sea often much complicates the coast protection problems. The reason is deficit of filling sediment on the coast-protecting beaches, which settle under the water. Consequently, two problems arise: efficiency of water-reservoir decreases and coastlines start to degrade what eventually ends with coast washing away and disaster. Main goal of is to develop the method of efficient solution of water-reservoir and coastal problems allowing maintaining th...

ESTIMATION OF CLIMATIC BACKGROUND AND ITS REGIONAL PARAMETERS

(STEF92 Technology, 2020-09-20, Lia Matchavariani, Giorgi Metreveli, Zaza Gulashvili)

Show more

The current global climate variability is leading to significant changes in meteorological and oceanographic elements. A climatic background is formed, under the direct influence of which the reservoir affects the climate. The aim of the study is to create a method that can assess the combined impact of the main climate elements for a specific time interval and region. The following parameters of hydro- and meteorological elements are selected as the characteristics of such background: arithmetic mean and correspo...

MULTI-TEMPORAL IMAGE ANALYSIS FOR ALAZANI RIVER (GEORGIA) MEANDERING CHANGE DETECTION

(STEF92 Technology, 2020-09-20, Mariam Tsitsagi, Lia Matchavariani, Georgi Ghambashidze, Dali Nikolaishvili, Elene Nikolaishvili)

Show more

Human impact along with other elements of the environment has a great impact on the processes in the river basins. River meander dynamics and mobility are important indicators of environmental change related to climate changes and anthropogenic activities at local and river basin scales. This paper presents a study of spatial and temporal changes meandering Alazani (Georgia) in its middle stream and downstream. Alazani is the border of the country and the bank erosion here has the environmental and political impor...

SPATIAL-TEMPORAL DISTRIBUTION, GENESIS AND TRANSPORTATION OF BOTTOM SEDIMENTS

(STEF92 Technology, 2017-06-20, Lia Matchavariani, Giorgi Metreveli, Davit Svanadze, Zaal Gulashvili)

Show more

Genesis, transport and accumulation of settled sediments of mountain rivers are such random processes in time and space, which are defined by the river flow rate (Q m3/s?c), height of the basin (IпїЅ), the inclination of the river and basin geology. Genesis and the volume of river sediment is the function of the climate and, in accordance with its cycles, it increases during the warming period and decreases as the temperature falls. The main natural factors for sediment formation are the glacier, erosion, landslid...
