State Hydrological Institute (SHI)

Department of Channel Processes Department of Channel Processes of the State Hydrological Institute is a leading organization in Russia in the field of the study of river channels and floodplains evolution caused by flowing water and scientific substantiation for varies projects in river engineering: hydro-, thermal- and nuclear-power engineering, navigation, irrigation, bridge-building, pipe-line transport, municipal economy, water-supply, alluvium dredging, urbanization and recreation.


Territory of investigations comprises all the geographical and economical zones of the former USSR. Research methods used - field, airborne, theoretical; hydrological, geomorphological, hydraulic; physical (hydraulic and airdynamic) and mathematical modeling. Measuring means - standard instruments and modern equipment - satellite global positioning system (GPS) combined with new echo depth-sounders, wide-band current acoustic Doppler profiler, Klein side scan sonar system, original devices and facilities for hydraulic laboratories. Data processing and presentation - on the geo-information base (GIS) with the use of modern computer software and hardware.

Introduction of research results - monographs, papers, reports, manuals, reference systems, recommendations for particular projects, monitoring methodology, assessment of a project impact on environment.

Fields of activities cover both calculation and prediction of natural processes, and solution of problems of the safety and protection of engineering structures.
