Abstract: The thesis is relevant to a problem of use space shooting and airborne techniques for hydrological survey of bridge passages. There has been developed a new valid approach to hydrological survey of bridge passages, based on use of remote Earth sounding methods, which are accomplished from an artificial satellite, an airplane or another aircraft. The mathematical models of drain process have been elaborated using space information for the purpose of the overall estimation of surface run-off conditions, study drainage network and storage basins characteristics as well as impound flood-lands forecasting and prevention. The high trustworthiness of identification of objects, engineering constructions, drainage network elements and underflooding boundaries is reached at photointerpretation. The remote sounding from an airplane can be used successfully for determination of the calculated probabilistic values such as levels, water consumption, streams rates, stream jets directions, quantity and structure of solid material transferred by water flow, river-bed modification. The functional dependence for determination of the overall and local values of offshore motion of sediments, backwater etc. on basis of aerial photography has been developed by means of a bridge passage stereoscopic model. The schemes for realization of aerial hydrometric measurements have been elaborated.

Keywords: remote Earth sounding, hydrological survey, mathematical model of drain process, bridge passage stereoscopic model, aerohydromethods.
