Construction development of forest-tundra areas shall take into account their peculiar characteristics: enhanced susceptibility of landscape components to man-made impact, presence of permafrost, and also insufficient exploration of environmental conditions. These factors make it essential to carry out a detailed investigation of natural and man-made conditions as a part of engineering and environmental surveys during environmental feasibility study of the projected construction in such areas. This work is dedicat...

The main parameter for calculation of waterway openings of bridges and pipes, as well as cross sections of water-draining meliorative ditches, is maximum water flow rate. So, the reliable calculation of this parameter is essential for selection of appropriate design solutions. Snow melt flood volume is mainly determined by the volume of water stored in the snow cover when melting begins, and flow rate пїЅ by the rash of spring snow melt flood. In its turn, snow stock is considerably depends on the degree of covera...

In connection with the significant destruction capability of tornado, the possibility of tornado passing through the areas comprising higher criticality rating facilities, such as nuclear power plants (NPP), is considered during the design and engineering (D&E) phase for such facilities. Corresponding probabilistic safety criterion in introduced into the decision-making basis concerning the consideration of tornado's impact onto the hazardous production facilities and destruction loads computation during the D&E p...

Atmospheric dispersion climatic conditions relate to main factors determining the environment ecological condition and radiation safety in the NPP area. This article is devoted to generalization of the author's studies concerning the atmospheric dispersion in the atmospheric boundary layer (ABL) for selection of the NPP sites and arrangement of ABL monitoring during the course of NPP construction and operation. Results of the ABL parameters climatic regime studies at Nizhny Novgorod NPP and Belorussian NPP are pro...
