Abstract: The paper introduces the composition, working principle and operation methods of multibeam sounding system as well as the theoretical basis of detection by unmanned submersibles vehicles. The detection practice for the energy dissipation pond in a hydropower station has proved that the combined application of multi-beam sounding system and unmanned submersibles vehicles is effective in detection of hydraulic structures and satisfactory results can be obtained.

Key words: multi-beam sounding system, unmanned submersibles vehicles, hydraulic structures, combined detection
