Groundwater flows forming in the south-western slopes of the Geghama Ridge are mostly transported and unloaded in the well-known groundwater basin of Katnaghbyur in Kotayk Marz of the Republic of Armenia. The article presents the results of electrical exploration studies. The depths of groundwater were determined by "Field Sustainability Sounding" method. The "PODBOR-4" computer program was used for interpretation of aforecited FSS field data.

Under the regularities of formation of groundwater, we understand the steady spatial, temporal and genetic relationships of groundwater with the geological and hydrogeological conditions and natural-territorial complexes of the region. As water-control criteria, increased fracturing, it's mainstream, lithological, geomorphological, geobotanical and other features should be noted. The presence of the above criteria allows you to identify promising areas for targeted field research. The presence of the above mentioned criteria allows to identify promising areas for targeted field research. Among these methods, one of the main ones we recommend is geophysical, which are successfully used in the search for groundwater in a number of volcanic areas.

Radiation field in natural and artificial underground voids is presented in the work. Based on field studies, carried out in Mozrov and Arji caves, it was revealed the intensity of radiation field in these voids is lesser than in ambient conditions because of absence of $γ$-ray radiation there, which are penetrate into atmosphere from ionosphere. This should be taken into account during the operation of the indoor premises, selecting tourist trips, and construction works.

The results of the analysis of the relationship between the intensity and condition of the shelter of interstate and republican highways of the Armavir Region of the Republic of Armenia are presented. The main cause of highway wear is low intensity. Roads have lost their operational significance and, therefore, order due to a decrease in road intensity indicators.

The article provides an analysis of the theoretical position of land degradation. The commonality of factors contributing to degradation was revealed, and their model was developed. The article proposed a method for assessing the rate of degradation based on this model. The above-mentioned provides an opportunity to assess the degradation in any territory and develop measures to combat them.

In the article the morphostructural zoning scheme of the territory of RA is suggested based on quantitative analysis of relief of topographic maps of territory. In the result morphostructural blocks and lineaments of observed territory were highlighted. Juxtaposition of gained results with geological and tectonic data was performed.

In the article influence of agricultural activities on land degradation with the help of Lori Marz example were assesed and analysed. It gives the opportunity to detect and manage negative anthropogenic interference, which will minimize land degradation in the region.

Based on the need to create a favorable economic conditions and increase competitiveness of country in the conditions of market relations, Armenia joined various regional integrational associations. After joining the EAEU there were many geopolitical changes in Armenia. Today, the consequences of these changes are mainly assessed based on the analysis of statistical data of foreign trade and foreign investment. Meanwhile, due attention is not paid to assessing the created situation, analyzing the opportunities that have arisen and using competitive advantages. The article describes the influence of geopolitical changes on the economic development and investment opportunities of the Republic of Armenia.

The current tendencies of development and changes taking place in the settlement system of RA frontier, mountainous and high mountainous territories are largely dependent on historical-geographical features of those areas among other factors. Historical-geographical analysis of settlement pattern basis formation of RA frontier, mountainous and high mountainous areas have been done in the article.

The scientific mechanism of the service, developed on the idea of noosphere, creates conditions through its differentiated approaches for the following: reconstruction and greater sustainability oecumene's social life space structures, creation of social life's sustainable space systems through "service hubs" in wildlife. For the purpose of addressing these issues, it is necessary to use scientifically grounded mechanisms for creation and improvement of the forms of social life through Services sector activity.
