Abstract
The regularities of technogenic eutrophication of rivers under the impact of mining facilities are studied. The main specific features of succession during anthropogenic eutrophication were analyzed. Methods of quantitative bioindication and risk-analysis of these successions for the river ecosystems are developed. This takes into account a variety of alternatives for the possible development of environmentally dangerous events. As a result, the most likely environmental damage is estimated and given its cost equivalent. This opens up the possibility of forecasting and managing the situation on a quantitative basis. Developments allow forecasting the level of technogenic impact on the ecosystem, to determine and regulate the most likely technogenic ecological damage.
