Underground waters in the volcanic zones are not directly reflected in the materials of long-range shooting. Analysis of aerospace photos shows that in volcanic regions the basic standards of prediction consist relief features. Thus, the use of aerospace materials let us reveal buried valleys, which can be associated with interlava and underlava water flows.

In the article multiple examples of geophysical investigations in mountainfolded areas for hydrotechnical tunnel constructing are analyzed. Mountain-folded areas have difficult structure and for investigations is required a special complex of geophysical methods.

In the article the results of laboratory studies of clayey rock samples of three different consistencies and humidities are discussed for the purpose of revealing the distinctive features of shear strength values under the different conditions, i.e. under the cyclic shearing stresses. It is experimentally substantiated that appropriate adjusting of the accepted design schemes for a real assessment of slope stability is a problem that requires a prompt solution.

In the article by the application of the method of isolong an attempt was made to research the main structural features of the Earth Crust sedimentary layer for Vayk-Syunik region. For this purpose the morphostructural models of the sedimentary layer for research area were composed, which characterize its different depth horizons, and comparative analysis were made with the structural heterogeneities of the crystalline fundament surface.

In the paper the types and causes of landslides of the Armenian highland is analysed. Their highest activity is observed in the provinces of Trabzon, Rize, Erzurum and Shirnak (all in Turkey); in the Adjaristskali river head and in the Bordjomi gorge of Kura River (Georgia); in the provinces Vayots Dzor, Ararat and Tavush (Armenia). The most of them are coincided with zones of active faults and hydrothermal changed rocks and the active use of mountain slopes increases the risks of their displacement.

In this article the problem of providing to organs of executing control of land resources with complex data (including the appropriate maps and databases) about land resources has been studied. Today it is impossible to solve this problem without appropriate software, geoinformation system and multi-scale maps, which form basis for them. Each government proceeding from its territory and features determine succeeding scales of base maps. These maps, which are created in uniform coordinate and high-rise systems, are intended for solving different tasks arising before the country. In corresponding software package the usage of topographic and cadastral maps together with remote sensing will allow to derive multi-scale base map consisting of several large-scale theme groups and layers.

In the article the current situation and development issues of the tourism industry in the province of Tehran are given based on the analysis and generalization of factual material and statistical data of basic infrastructures, such as hotel service, air transport, vehicles, guides՛ institute and catering services.

The migration and resettlement questions in RA are discussed in the article. The population migration ratio of different settlements and their changes during 2002 till 2015 are calculated also, as well as the structural and territorial movements due to migration in RA are discussed. One can find different suggestions, which concern the productive interaction between migration and resettlement.

Considering the modern conditions of RA socio-economic development and strategic reasons, socio-economic development of contiguous areas and strengthening the defensibility of the country has a special importance. Based on the analysis of statistical data, the tendencies of RA frontier areas settlement dynamics (of population and settlements) over the last 3 decades and the problems connected with those tendencies have been revealed in the article.
