Purpose: to conduct scenario studies of the hydrodynamic model of the Proletarskaya irrigation system to assess the impact of an additional regulation structure on its operation mode.
Materials and methods. To conduct scenario studies, a hydrodynamic model was developed for the section of the Proletarskiy branch of the Don main canal with a total length of more than 30 km. The model is used to consider several scenarios.
Results. According to the scenario studies results of the hydrodynamic model of the Proletarskaya irrigation system, it was found that using the operation mode of the additional structure identical to the head one, it is possible to achieve a water level reduction in the canal within 16 cm in the upstream and 80 cm in the downstream, which leads to a decrease in water storage by 45 million m³. Such levels make it possible to ensure the operation of the PR-1 canal in full, but it is difficult to predict the volume of water supply to water users located after the control structure at PK 1427. In this regard, the problem of selecting the optimal operating mode for the additional structure and structure at PK 1427 was solved. It was revealed that to ensure the specified criteria, the gate opening rate of the additional structure should not exceed 24.1 m BS, blocking on PK 1427 – 21.8 m BS. Such an operation mode of the structures allows saving about 30 million m³ of water during the irrigation period.
Conclusions. Based on the results of scenario studies, it was found that the presence of additional structures improves regulation and contributes to an increase in the water use efficiency. At present, the determination of geometric parameters and the selection of operation modes of such structures can be carried out on computer models, using the actual state of irrigation systems.
