Development of Priority Measures to Increase the Capacity of the Hydraulic Reclamation System, Produced Before the Implementation of Major Repairs or Reconstruction

Methods for protecting hydraulic structures and maintaining conditions for their trouble-free operation have currently been developed in sufficient detail and are widely used. The question is one of appropriateness, consistency, intensity and place of their application. In the context of a shortage of financial resources allocated for the restoration of hydromelioration systems, it makes sense to conduct an analysis of the distribution of costs for restoring the operability of hydromelioration systems in accordance with the Pareto Law. The Pareto law in its most general form is formulated as “20% of the effort gives 80% of the result, and the remaining 80% of the effort gives only 20% of the result.” In our case, as applied to linear structures, this means eliminating individual faults that have the most significant impact on the canal’s throughput. Such faults can be considered as bottlenecks. A bottleneck is a resource whose capacity to provide bandwidth is less than the demand for it. If the level of funding is insufficient or funding is delayed, bottlenecks in the system’s operation are identified in order to eliminate them and improve the performance of the HMS. In addition, the economic efficiency of the measures is determined. In our case, the bottleneck is a section of a linear structure whose capacity is equal to or less than that currently required. The decrease in throughput usually occurs due to a decrease in the canal cross-section due to various reasons. The decision on the method for restoring the functionality of the structures is made after a detailed examination, depending on the type and volume of work, the availability of available equipment and resources, including financial ones. When analyzing a specific facility (Sarpinskaya OOS of the Republic of Kalmykia), it was found that the cost of eliminating bottlenecks is 0.23% of the cost of major repairs. The above works are related to current repairs. Operation of a linear structure after such liquidation is a temporary measure, but it allows for water supply to irrigated areas currently in operation for a limited period prior to repair or reconstruction.
