In article the key parameters necessary for an assessment of a residual resource are considered and the conclusion, about lack of an effective method of an assessment of a residual resource for hydraulic engineering constructions is drawn. An overall objective of carrying out operational monitoring of a technical condition of water carrying out constructions are identification of deterioration of degree of physical wear, the reasons causing their condition, the actual operability of elements and development of actions for providing their various operational parameters, and also the description of a technical condition. The risk of failures and defects on vulnerable objects which many water carrying out constructions - tunnels, channels concern, dyuker, lotkovy channels and pipelines is most dangerous.
Keywords: the hydraulic engineering constructions which are water carrying out channels, nondestructive control methods, a residual resource, modeling, a technical condition.
