Criterial approach to substantiation of the best available techniques for engineering protection against hazardous techno-natural processes
Summary
Prediction of measures and construction of facilities for engineering protection from hazardous processes has a number of specific features that should be borne in mind while developing a method for substantiating the best available techniques. The mathematical tools that provide for substantiating the choice of a technology for engineering protection from hazardous techno-natural processes, that can be assigned to the best available techniques, are under development. One of the approaches is presented that allows, on the basis of quantitative assessments, to substantiate the choice of an option of engineering protection against hazardous techno-natural processes. This approach is based on the expert-analytical method for assessing the risk from hazardous natural-technogenic processes that has been widely used in recent years. Mathematical tools have been proposed that provide for reasonably approaching the choice of the best available technique for engineering protection against hazardous techno-natural processes, taking into account the capabilities of the owner, his position in the current situation and development prospects.

Assessment of safety and risk of flooding of urban industrial territories: expert-analytical method
Summary
The main provisions of the expert-analytical method for assessing the risk of hazardous processes are stated; the method formed the basis for the development of a number of methodological recommendations and state standards. On the basis of this method, a technique is proposed for assessing the safety and risk of one of the dangerous natural-technogenic processes – flooding of urban industrial territories. The main factors of the harmful impact of this process on the structures located in such territories are indicated. It is shown how risks and damages from flooding of urban industrial territories can be estimated on the basis of the general methodological approach to assessing risks from hazardous techno-natural processes. As a result, criteria for safety and risk of flooding were obtained and a mechanism for assessing the risk of flooding was developed. The features of the assessment of the risk from flooding of urban industrial territories at the federal, regional and local levels are revealed.

Expert and analytical assessment of the safety and risk
in analyzing the hazardous impact of techno-natural processes
on the facilities and environment
Summary
In accordance with the general provisions of the expert-analytical methodology for assessing the risk of hazardous impact of techno-natural processes of various origin on the facilities and environment, a method for calculating the risks of techno-natural processes is proposed. The method is based on a detailed analysis of research materials on the hazard level of processes and vulnerability of the facilities and environment, a quantitative assessment of the hazard level and degree of vulnerability, followed by the use of probit analysis to calculate the formation of risks. For the classification of safety and risk levels adopted for work, the criteria are determined and their values are defined that provide for assessing the levels of safety and risks of hazardous techno-natural processes of various origin. The proposed method for assessing the risks of techno-natural processes is illustrated by a more detailed study of the classification and assessment of the safety and risks of hydraulic engineering structures of different categories.
