Economic assessment of ecological damage to surface waters as a result of emergency situation

Abstract

The purpose of the present research is the analysis of emergence of the most probable emergency situations on the hydrotechnical object which is long time in operation, and also economic assessment of effects of surface water pollution of emergence of the emergency situation which resulted on hydrotechnical construction on the example of Raychikhinsky state district power plant. Hydrodynamic accidents happen because of design errors, constructive defects of constructions, violations of the rules of operation, discrepancy of spillways and spillovers of water through dams more often. Besides, it is impossible to miss possibility of acts of sabotage and blows to such constructions. Hydrodynamic accidents are consequence of failure of hydrotechnical constructions therefore the uncontrollable, powerful flow of huge mass of water with high speed floods extensive territories, bearing destructions and death of people. In the provided article the main characteristics of hydrotechnical constructions of Raychikhinsky state district power plant are in detail considered, the main dangers to the population at accidents on these constructions are defined, scenarios of possible accidents and emergency situations of natural and technogenic character are considered, economic assessment of the ecological damage caused to surface waters is provided. Safety of the population and steady functioning of the main objects of economy is provided with minimizing of probability of emergence and minimization of damage from the listed dangers.
