Based on catalog of Survey for Seismic Protection MES RA the spatio-temporal distribution of hypocenters and epicenters of earthquakes of the territory of Armenia was studied and was offered appropriate conclusions. Data were handled by using Z-map program.

Armenian (Noyemberyan region) zeolite bearing tuff absorption-desorption kinetic has been studied. It has been found out that Armenian zeolite bearing tuff has the ability of separating heavy water from HTO+H₂O system. The amount of sorbent heavy water increases with increasing zeolite content in the tuff. Desorption of heavy water from zeolitic tuff depends on zeolite phase content, particle size, surrounding liquid chemicals and temperature. Temperature decrease of the surrounding liquid (from 90°C to 25℃ ) and the increase of sorbent particle size (from 20 to 80 mkm) reduces heavy water desorption. Acid environment causes complete desorption of heavy water from zeolitic tuff.

In the article for the first time are given aggregated data of all metal deposits tailing dumps of RA, are examined issues of their classification by hazard category, as well as other important unresolved problems related to tailings and are pointed the ways of their solution.

In the article the results of effective application of electroexploration (Vertical Elektro Sounding (VES) method) for the study of landslide processes in Urtsadzor–Goravan area (catchment of R. Vedi) are presented, which were intensified especially after the construction of the main channel for irrigation of lands. Surface landslides shifts are installed at depths of 10–12 m and 20–25 m, relief of the landslide surfaces and boundaries of their distribution are mapped. Locations of wells are recommended in connection with the preparation of geotechnical model for calculating the stability of landslide slope.

The article substantiates the use of subsurface drainage of horizontal ring type to protect the bases of various kinds of structures in the territory of Dilijan International School against impoundment of groundwaters. As a result of analytical calculations, providing the hydrogeological conditions of the object, all the relevant parameters of the drainage system have been identified. These parameters correspond to the building regulations, requirements for the construction of ground structures and underground utilities that would be constructed on the site of the school, and will be protected from groundwater impoundment for the entire period of their operation.

In the present work the methodological errors conditioned by the spatial gradient and difference of variation of magnetic fields are observed. It has been found that these errors are not connected with the accuracy or sensitivity of the apparatus. If it is granted that the expected tectonomagnetic effect is several nTl, thеn the attempts to discover it may be considered impossible.

With the help of algebraic addition of strength and substance method was calculated the pit wall stability and overburden dump for Lunevsky limestone deposit. Executed calculations are evidence of the fact that the choice of dump angle 50° is substantiated in case, if worked out areas were filled by 15 m overburden dump layer.

One of the highlights of the research during the aesthetic evaluation of the landscapes is the classification of natural territorial complexes. On the basis of evaluation should be the expressiveness of the component. In other words, the components of the landscape that attract tourists should be in the foreground. Such components are relief, water facilities, vegetation, as well as anthropogenic complexes.

The article explains the role of greening of agriculture in terms of rational use and protection of natural resources, as well as improving the quality of natural environment. Agriculture greening is a new stage of culture, which provides a transition from the consumption principle to careful nature use, refusing the extensive use of natural resources.
