Hydrological monitoring at international rivers and basins

The objectives and principles of organization of hydrological monitoring at international (transboundary and boundary) rivers of Russian Federation are discussed. We developed an international rivers classification which concern their location in relation to national boundaries and further used for the optimization of hydrological monitoring network. Rivers in the basin of the Amur and the Selenga are used as an example to discuss the problems of introducing special technologies into the practice of hydrological monitoring under the incomplete hydrometric knowledge of international rivers. Perspectives of the application of methods of water regime assessment, remote sensing application to river hydrology, and mathematical models of pollutant transport are demonstrated.
