The evolution of views and practical decisions regarding the problem of collecting payment for the use of surface waters with regard to their quality in the former USSR and present-day Ukraine is discussed. A simple and feasible method is proposed for differentitation of regional (basin) rates of payment for the use of surface water in Ukraine with allowance made for its quality assessed based on a system of environmental classifications.  相似文献

Based on experimental data on the level and elements of the water balance of the Ust’-Ilimsk reservoir, we outline the characteristic properties of the long-term and seasonal regimes of its impounding and drawdown under normal operation conditions (1977–2008). We demonstrate the role played by the individual components of water input and output in the formation of the reservoir’s water regime.  相似文献
