The analysis of the experience of examining the Belarusian waterworks and sludge storage facilities of JSC «Belaruskali» showed that the causes of emergencies can be defects in the survey, design, construction and operation of structures. At each of these stages there are risks of accidents. The risk assessment is based on the results of control and analysis of quantitative and qualitative characteristics of the state of the structure, the environment in the zone of its influence, natural loads and impacts, expected damage from an accident or destruction of hydraulic structures, compliance with the conditions for its safe operation, etc. A similar approach to assessing the risk of accidents in hydraulic engineering structures for the entire set of factors affecting the reliability and safety of structures, is the basis of the regulatory documents developed in Russia. With appropriate adaptation, this approach can be used to assess the risk of accidents at reservoirs of the Republic of Belarus. The indicators for assessing the hazard of accidents and vulnerability of hydraulic structures, as well as lists of risk factors and their distinguishing features for each indicator, are supplemented and improved, compiled by the author together with G. G. Kruglov, V. V. Ivashechkin and O. A. Murashko, typical for Belarusian reservoirs. They can be recommended for practical use in organizations as standard documentation for assessing the possible risk of accidents and the state of hydraulic structures during operation, as well as when conducting surveys of hydraulic structures etc.
