Software and hardware support (SHS) to carry out operational monitoring for technical state of water conveyance structures designed for determination of various parameters of defects and damages as well as for computation the predictable period for residual life of their elements are described in the article. As a result of numerical experiments carried out zones of water conveyance structures that can have characteristic damages of the same type were marked out. This makes it possible to assure orderliness in the process of laying profiles for georadar sounding and determining points where measuring of concrete strength is necessary when inspection on location is carried out. A technical result obtained with the support (SHS) is revealing influence of defects and damages for both protective coat itself and the state of ground under it on forming seal failures and subsidence during early stage of their forming. The support (SHS) makes it possible to assess geometrical parameters for each of the defects: location, depth, width, height as well as operational evaluation of residual life: forecasting the total number of freezing and thawing cycles both passed during the period of operation and remained up to the loss of bearing capacity for ferroconcrete elements of water conveyance structures and complex effect of some factors on the structure reliability, the most typical of which being abrasion, leaching processes and the degree of wear on sections (areas) with different hydraulic characteristics.
