In the article to research water levels in the Zhinvali water reservoirs by field and theoretical research and using GPS and GIS technologies has been established dynamic of water reservoirs changes in the suitable coordinates and has been made water reservoir maps and is lined in the 3D format. By using of GPS coordinates and digital maps has been established water horizons of Jinvali water reservoir in the absolute marks and has been calculated water levels volume. To forecast the filling of the Zhinavali water reservoir by solid sediment in 2018 conducted field experimental researches in the catchment basin of river Tetri Aragvi. It has been established main hydrological and hydraulic parameters of the active erosion-debris flow tributaries of river Tetri Aragvi. It has been calculated erosion coefficient considering the degradation of the slope. By calculation is determined, that in the river Tetri Aragvi catchment basin the value of 1 % maximum discharge changes Q1% = 70,0 – 550,0 m3 /sec, and erosion coefficient - E = 0,73 - 1,62, with suitable fifth class of erosion and intensity 50-100 tone/ha in the year.

Georgia is one of the most vulnerable countries to

natural disasters within South Caucasus Region. In recent years,

the disaster risk has increased due to faulty land-using.

Outstanding building codes lead to inadequate building

construction. There is a lack of real data on natural disasters and

the impact of mudflows, floods, debris flows etc. on land-use

planning and prompt actions after above mentioned catastrophes.

Therefore it is important task to carry out assessments of critical

structures sensitive to natural threats such as dams and reservoirs.

In order to be able to improve the resistance of hydraulic

engineering structures it is necessary to utilize a formal risk

analysis framework, such as the Critical Asset and Portfolio Risk

Analysis (CAPRA) method. The scientific article examined the

creation of a framework for the condition of the earth dam and

risk management using the analysis of the critical state and the

risk portfolio, which was developed by Professor Billal Ayyub

who represents Maryland University in USA, to examine human caused threats, such as terrorism events, and natural hazards, such

as flooding due to dam failures, with focus on potential failure

modes due to deterioration. For this purpose, based on the field

and theoretical studies, the regulation of hydrological (floods,

debris-flows, snow avalanches), geological (erosion, mudflows),

and seismic (earthquake), as well as those natural disasters formed

in the water area of Zhinvali Reservoir, which determines the

stability and reliability of the Zhinvali Earth Dam, is estimated

using existing statistical data and theory of reliability and risk.

Special attention is paid to the safety of the population living in

the risk zone, as well as the development and evaluation of

methods and principles of the impact of expected disasters.

The article describes the importance of the Alazani Valley landslide for one of the strategic directions of agricultural development. Experimental observations presented in 2010-2017 indicate the dynamics of Alazani-based explanations, which are compared with existing data.
Deeper efficiency. The effect of drainage was determined by the depletion of groundwater and dry water by the real possibility of melting of strong algae soils on the right bank of the Alazani Valley (after summer and autumn burns).

 The article describes the characterization of Alazani 45 ha test-drainage polygon. Land reclamation assessment of the mentioned object.
  The results of water shortage, mineralization of collector runoff waters, criteria for assessing the ecological condition of saline-ameliorated soils are presented.
It has been established that the process of gradual desalination of saline reclaimed lands is irreversible and the perfect drainage-collection network is the basis for the ecological improvement of saline highly mineralized ground waters.
