Methodical support of integrated management of water resources of the basin of transboundary rivers

Abstract

Based on the principles of reasonable, equitable and rightful use of water resources in accordance with the concept, adopted at the «Agenda of the 21st Century» at the UN in Rio de Janeiro and developed by the European Environmental Agency – «DPSIR-analysis», as a method of systematizing the information and identifying the cause-effect connections in order to solve the problems of integrated water resources management in transboundary rivers, the system of integral criteria of geo-ecological restriction is justified, ensuring the restriction and prevention of the negative influence of transboundary impacts. As an integral criterion for geo-ecological restriction, an indicator of the water availability curve taking into account climate change is developed, that is, the arithmetic average of the statistical series of the annual river flow, geomorphological schematization of the catchment area of the transboundary river basin, taking into account the heat and water availability of their landscape system, the maximum pollution of the river flow, territorial planning water use based on integrated parameters using climatic, geological and geo-morphological, hydrological and landscape factors, the ecological situation of the hydro-agrarian landscapes of the river basin catchment in “soil-plant-human” systems, the maximum permissible level of use of river basin water resources and ecological runoff, the available land resources of the river basin catchment and the ecological services of the river basin catchment, possible area of hydro-landscape systems in the catchment areas of river basins, a comprehensive assessment of environmental, economic and social damage caused by human activities. Methodological substantiation of the criteria of geo-ecological restriction when using the water resources of the transboundary river basin, as a method of systematizing information and highlighting cause-effect relationships in order to solve the problems of integrated water resources management of transboundary rivers, covering all levels of the water use process from the formation and shopping of water resources and their watershed dispersal zones transboundary river basins can be used in the planning and implementation of integrated Water Management (IWRM).
