A map of groundwater freatic surface for some landslide-prone regions of Armenia has been compiled in GIS. Archival materials were used, as well as fund materials of more than 10000 wells, geomorphological and hydrogeological data, data on the river network and watersheds. Having revealed some relationship between the depth of the groundwater and distribution of landslides the presented map allows to highlight a stable and risky terrains. Danger of landslides is high in the terrains with a shallow groundwater, and vice versa. At the same time, it is necessary to take into account the impact of periodic fluctuations of groundwater level on the landslide development. It is due to periodic changes in the stress state of the landslide mass. Given the above, sites with periodic fluctuation of groundwater level can be considered dangerous and unstable.

The population of a number of villages, including Koghb village of Noyemberyan region suffers of drinking water shortage. The article substantiates that the lack of drinking water of Koghb village can be partially compensated by the groundwater occurring in the floodplain of left-bank of the middle reaches of the Koghb River. According to hydrogeological calculations the capacity of borehole tapped in the floodplain is about 7 L/s, which according to acting norms is sufficient for drinking needs of 3000 people.

The work is dedicated to landslides, occurring in Armenia and the main types of landslide deformations. For each of the five areas identified by geotectonic features, the engineering geological conditions, including landslides and mechanisms of their occurrence is presented. The following landslide deformations are singled out for landslides occurring in Armenia: landslides, flows, slidings, avalanches, plastic landslides and complex transition landslides.

The article provides the current concepts of ecological, self-regulatory, active and sport tourism in Russia, highlights the present state of ecological tourism, and deals with its rational spatial organization in the Ural territory and Perm Krai.

In this article it has been given the characteriztic of anthropogenic overloading of the rivers. In the territory of Armenia has been analyzed and assessed the degree of anthropogenic overloading of relatively large rivers for the first time. The rivers have been grouped according to the degree of anthropogenic overloading; weak, medium and strong, and the schematic map of spatial distribution of the rivers' overloading has been created.

It is marked that landslides of various sizes and activity are widely spread on the southern slope of the Marmarik River valley. Bringing in exploitation of Marmarik reservoir will provoke forming and evolution of secondary technogenic geomorphological processes, which will reveal itself in the form of landslides or activization of already available landslides on its banks. The southern slope of the reservoir opposite the Tsahkamarg river mouth and convex slope a little above the dam, steeply moving to water are the most dangerous areas of landslide appearance displacements. It is offered to carry out detailed geomorphological and tacheometric investigations for well-founded forecast of dam banks treatment.

It is analyzed in this article the main preconditions of the formation of the rural areas and rural population of Aragatsotn region. It has been revealed the dynamics of rural areas and population trends according to altitude zones and overpopulation factors.

The article considers the issues of new field of scientific knowledge the science of service. The author analyses the views on the subject of its study, high lights the importance of this problem not only from a scientific point of view, but also from the perspective of the educational process in the profile "Service" and "Tourism" assumed the formation basic knowledge about the service. The author distinguishes understanding of service in the narrow and broad sense and proves his point of view, but also pays attention to the correlation of the concepts of service sectors.

In the article, based on the materials of deciphering aerial photographs, geophysical studies and water balance calculations for the Akhuryan River basin has been compiled a relief map of the regional impermeable rocks. A centered way of groundwater movement (paleovalleys) has been installed and estimated the value of the groundwater flow of the basin. The obtained data can be used for more detailed and targeted prospecting and exploration of water.
