FACTORS DETERMINING THE FEASIBILITY OF OPERATING A HYDRAULIC STRUCTURE

Abstract

The issues of the expediency of further operation of the hydraulic structure, both as part of the irrigation and reclamation complex, and in case of loss of economic purpose, are considered. The situations in which the facility operation may be inappropriate are listed. It has been established that in a number of cases the loss of economic purpose and the unsatisfactory level of safety cannot serve as a basis for the liquidation of the structure. A pond or the reservoir located in the HTS upstream and, for various reasons, not being part of the reclamation complex, during operation become an element of the local ecological system, the violation of which may be undesirable. Such structures play the role of a fire-fighting reservoir, both in settlements and in a fire hazardous area, become an object of recreation, etc. In this case, we are talking about the reprofiling of an artificial water body. The final solution of the problem, as a rule, requires a preliminary analysis of justifying materials, including technical, economic and environmental studies, as well as taking into account the social requirements of the local population. Examples of decisions on conservation / liquidation or reasons for the further operation of hydraulic structures are given. The examples are taken from the works of the Department of hydraulic engineering and hydraulics and laboratory of the HTS safety of the irrigation complex of VNIIGiM named after A.N. Kostyakov, including on declaring the safety of hydraulic structures.
