State Hydrological Institute . Hydrometeoizdat . Leningrad, 1985. The Recommendations reveal the possibilities of using materials of different types of aerospace surveys for the analysis of the channel process at: typification of the riverbed process, determination of planned deformations, ground work, assessment of anthropogenic impact in river basins, restoration of the history of river development. Recommendations are intended for scientific, design and production organizations of water management profile. Foreword by . Characteristics of Aerospace Information.
