【 摘 要 】

The article contains the results of studies of integrated analysis and integrated risk assessment due to flooding for the mouth of the river. Selenga and the development of recommendations for the implementation of measures for engineering protection of the population and economic facilities. In the dynamics since 1931 the hydrological situation of the maximum monthly and multi-year levels and water discharge has been considered, the analysis of genesis, features of formation and mechanism of flooding is given. Scales of possible flooding, underflooding and a list of economic objects within the territory under consideration are presented based on the simulation of flooding zones at estimated water levels of a given probability of exceeding. Estimates of damages from flood floods of 1% of supply are shown. Proposed measures to protect the territories with an assessment of their feasibility and cost-effectiveness.
