Intelligence Property

The mission of the Institute of Hydrogeology and Engineering-Geology is to support the strengthening of scientific research in the field of geology in Georgia, in particular, in the field of hydrogeology and engineering-geology. Raising the scientific potential of these fields is of great importance for the development and progress of the country. Therefore, the management of the institute considers it necessary to intensify scientific activities in this field in order to properly conduct the necessary research in construction, transport and other areas. It is also very important to list the freshwater and thermal water resources across the country and to manage them properly. Solving these issues is impossible without scientific research. In order to fulfill its mission, the Institute aims to find and attract the most advanced modern technologies and technologies in the world, to use modern research methods. It is important to take these steps, because it is impossible to increase the current scientific potential without them. This direction is also aimed at the fact that the institute should attract young staff, give them relevant education, develop the skills that will be useful to them in this activity. To achieve this goal again and again we need to get acquainted with and master new technologies and master modern methods of research. In order to fulfill this mission, the Institute also aims to find experienced foreign partner organizations that will stand by it, share their experiences and establish contacts through which modern research approaches will be introduced in the Institute.

GNSF/ST07/5-21399888 ლარი01.01.2008-12.31.2009Teimuraz IashviliGia Iashvili; Shorena Petriashvili; Marina Tkhinvaleli. Water supply of urban areas with drinking water is a problem of today's world. It is also problematic for the arid zone of the mountainous region of Georgia. For example, the city of Gurjaani is supplied with drinking water from a river 17-20 km away. By extracting Alazni filtrates at a height of 150 m. According to the data of the city municipality, the annual cost of electricity is 0.498 million GEL. The main essence of the project lies in the accumulation of excess surface runoff during spring-autumn floods in alluvial-proluvial geostructures, which will be used for their further drinking water supply. The development of technology for the accumulation and water intake system of excess surface water runoff in alluvial geostructures represents the novelty and scientific value of the project. Researches were conducted in Kakheti region. In particular, river in the territory of Gurjaani municipality. In the ceiling bed. In order to accumulate surface (river) runoff and shallow circulation ground water formed there, a prospective section was selected, where hydrological, engineering geological and hydrogeological investigations were carried out. The geotechnical characteristics of the aquifer (alluvion) will be studied in detail (composition, physical, strength, deformation and filtration parameters). Special investigations will be conducted on the clay soils used to build the body of the sub-bed diaphragm, for which the optimal moisture content will be determined - determination of density, strength, deformation, filtration coefficient. As a result of processing the normative characteristics of the geotechnical parameters with the methods of variational statistics, the reference (design) values were determined. The arrangement scheme of the anti-filtration diaphragm of the sub-bed clay has been developed, which can be used both directly in the design and in the construction process. Also, a scheme for protecting the surface of the diaphragm from washing has been developed. According to the obtained results, a new energy-saving technology was developed under the name of sub-bed drainage facility. Within the framework of the project, 2 scientific papers were published and 1 invention patent (utility model) was obtained.
AR/147/3-103/14Elaboration of a New Energy Saving Technology with the Purpose of Solving the Problems of Supplying the Urban Territories in the Arid Zone of the Mountainous Regions of Georgia with Drinking WaterState scientific grant competition for applied researchSHOTA RUSTAVELI NATIONAL SCIENCE FOUNDATION OF GEORGIA171800 ლარი28.04.2015 - 28.04.2017Tarkhan TevzadzeGiorgi Omsarashvili; Feride Lortkhipanidze.Supplying the urbanized territories with drinking water is the problem of today’s world. It presents a problem for the arid zone of the mountainous regions of Georgia, as well. For example, City Gurjaani is supplied with drinking water by means of pumping filtrates from the River Alazani at the altitude of 150 m. According to the data of the City Municipality, the annual consumption of electric power equals to 0.498 mln. GEL. The major essence of the project constitutes in accumulation of abundant surface runoff during spring and autumn high water level in alluvial-proluvial geological structures with the purpose of their further utilization for supplying drinking water. Elaboration of the technology of the system of accumulation and water intake of abundant surface run-off in alluvial geological structures presents the novelty of the project and scientific value. For example, the project envisages arranging an underbed clay diaphragm aggregated with the waterproof layer located in bottom layers of alluvion. This stipulates accumulation of water in alluvial geological structure and its planned supply to the reservoir located at the dominated hypsometric date of the populated area. Creation of such a water-containing layer by accumulation of abundant surface flood run-off in alluvial geological structure excludes: - Losses of abundant surface run-off; - Pollution of water with organic waster; At the same time, it will facilitate water purification by means of filtering in alluvial deposits and reverse filters of the drainage system. The presented technology saves energy as it excludes the costs of electric power for pumping the filtrates into the reservoir. It saves energy because the water is transported to the reservoir with gravity flow. The criteria of recognizable evaluation will be set in the grant project, on the basis of which the designing will be carried out considering the expected consumption of water and social-economic parameters. Successful implementation of the grant project presents a prerequisite for creation of water reserves and significant improvement of supplying the urban territories with drinking water. With the presented technology it will be possible to supply and manage the reserves on regular basis and according to the plan during the low level of surface run-off. In this aspect, supplying the populated and urban territories in the arid zone with drinking water will exert positive influence on the demographic factor and activation of the population in agriculture. In case of successful implementation of the grant (further project) research of the maximum run-off of the River Cheremi, the criteria of recognizable evaluaiton of the geological structure envisaged by the project will become a basis of the perspective of using the run-off of a great number of gullies existing on the slopes of the Tsivgombory Ridge with the purpose of supplying drinking water. This, on its part, will stipulate to form a wide market of domestic consumption and solve a great number of social-economic problems.The main target of the project is to work out new power saving technologies, which ensures the water supply of urban territories. In the first place we worked out the method for finding prospective water intake in the river valleys which are built with rocks of alluvial and prolluvial structure, which plays a decisive role in the development of power saving technologies and which involves the investigation of geo-morphological, geological, hydro-geological, hydrological factors, and chemical and physical properties of water, climate factors, etc. According to the mentioned method, the water accumulated in the valley shall be supplied to the settled area using a self-flow mechanism. As long as potable water problem is especially active in the towns and villages of Kakheti, the field and reconnaissance works according to the mentioned method were carried out in the valleys on the north-east slopes of the Tsiv-Gombori Ridge. The surveys revealed that such alluvia and prolluvial structure prevails in the valley of the Cheremiskhevi River. From the absolute elevations between 647.73-650.51 meters potable water may be supplied to Gurjaani via self-flow. In accordance with the tasks planned in the scientific projects for obtaining grants, geological and hydrogeological works were carried out on the study site. The central and exploration and exploitation water wells were arranged on the first terrace of the Cheremiskhevi River. Appropriate maps were also made (topographic, geologic, engineering-geologic, hydro-geologic and hydrologic), including the lithological sections. Test pumping were carried out in the central and exploration and exploitation water wells, which gave us interesting and important results. Filtration ratio K, and discharge parameters Q were determined, as well as ground water circulation velocity and the changes of their levels in the wells. As a result of field and hydro-geological investigations it may be concluded that there are significant underground water horizons in the alluvial and prolluvia structure if the Cheremiskhevi riverbed. Investigation of drinkable properties of filtered waters existed in the alluvial and prolluvial deposits of the Cheremiskhevi River valley was carried out in the field and laboratory conditions. As a result of investigations it was defined that the water were hydro-carbonate calcium and that the chemical and physical content of waters taken in this period complied with the requirements of Technical Regulation of Potable Water approved by an Ordinance N 58 of 15 January 2014 of the Government of Georgia. According to bacteriological surveys conducted in March, December and July 2016 it turned out that the water was polluted, although after taking some water treatment measures, the water will meet the requirements under the above mentioned standard. On the basis of all above mentioned surveys, a new power saving technology, named: “Water Intake Structure underneath the Riverbed” was developed (the invention was patented), which accumulates water in alluvial and prolluvial geo-structures existed in the rivers with permanent (continuous) or temporary discharge, which excludes the electricity expenses and which is economically far more effective than those which are currently approved – the artesian water intake wells.According to the obtained results, a new energy-saving technology was developed under the name "underwater reservoir structure". Within the framework of the project, 2 scientific papers were published and 1 patent for the invention (utility model) was obtained.
