The Subject of Research is water resources, hydrological regime and hydroecological state of Tyligulskiy liman. The Research Object is Tyligulskiy liman, which is situated in the north-western part of the Black Sea area. The research purpose is definition of the role of natural and anthropogenic factors that form the present-day hydrological regime and hydroecological state of Tyligulskiy liman, and development of guidelines for implementation of water management in the watershed of Tyligulskiy liman in view of the human impact and the climate change. The Methods of Research are traditional methods of statistical processing and analysis; stochastic 'climate-runoff' model for assessment of water resources of the rivers with the climate change and the water management taken account of; numerical modeling for formation of water and nutrient flow from the catchment, water-salt balance, hydrodynamic, hydrological and hydroecological processes in the liman. An integrated physical-geographic, socio-economic, hydrographic characteristics of Tyligulskiy liman and its watershed; description of natural resources of the liman and conservation issues; analysis of hydrological and hydro-ecological regimes of the liman under present-day conditions are provided. Trends in climatic factors of runoff formation in the liman watershed over the past decade; changes in water resources of the rivers in the basin of the liman that occurred as a result of the climate change; effect of water exchange with the sea on hydroecological regime of the liman are given assessment. The most likely climate change scenario for the region under research in the 21st century is identified. Original models of water-salt balance and eutrophication of waters in the liman are developed, calibrated and verified. Scenario prediction for changes in freshwater inflow from the catchment to Tyligulskiy liman, fluctuations in salinity, concentrations of mineral and organic forms of nutrients, oxygen content in the 21st century are presented. Effectiveness of different scenarios of hydro-ecological management of Tyligulskiy liman, with the climate change, the human activities and conditions of water exchange with the sea taken account of, are evaluated on the basis of model calculations.
