“…прошедшего столетия, возникают проблемы водообеспечения потребителей в условиях маловодности [1,2]. Это связано с неудовлетворительным техническим состоянием гидротехнических сооружений (изменение геометрических характеристик каналов, отсутствие автоматизированных средств измерений и регулирования), а также с изменением схем водораспределения из-за преобразования крупных хозяйств в более мелкие -фермерские [3,4].…”

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.

Purpose: to analyze the work of the information and analytical system for monitoring environmental parameters “Emersit-M35”, namely, daily data on flows and water levels from measuring complexes no. 239 and 241, located on the Temernik river, as well as to define the dependence of the flow rate on the water level and to calculate the runoff coefficients based on the data analysis obtained from the measuring complexes of Emersit-M35 environmental monitoring system on the Temernik river for the entire period of its work. Materials and Methods: the daily data on the flow rates and water levels from the measuring complexes no. 239 and 241, located on the Temernik river were analyzed, including graphs for comparing flow rates and water levels, the calculated values of the runoff module for 2018–2020 were presented, and the dependencies Q = f(H) for the entire operation period of the studied measuring complexes were determined. Results: it was found that there was a synchronization of the graphs of the flow rates and water levels on the measuring complex no. 241, and the stability level of the connection Q = f(H) here was more than 80 %, while there was no connection Q = f(H) on the measuring complex no. 239. It is noted that the reason for the absence of this connection is the location of the mentioned measuring complex which is subjected to the influence of the Don river. Conclusions: despite the revealed fact, the studies performed indicate the possibility of using the data obtained from the measuring complexes for the study and analysis of flow rates and water levels.

“…Высокая отдача от орошаемого земледелия не вызывает сомнений.Однако дальнейшее увеличение площадей орошаемых земель сдерживается ограниченностью водных и материальных ресурсов. Так, на юге России практически все водные ресурсы уже исчерпаны, и увеличение орошаемых площадей возможно только при оптимизации водораспределения[9], в т. ч. за счет автоматизации учета воды в оросительных системах[10], или в результате переброски части стока рек восточных регионов страны [11]. В 2020 г. мелиоративный комплекс Южного федерального округа (ЮФО) России столкнулся с проблемой естественного дефицита стока рек, что привело к низкой наполняемости водохранилищ и снижению лимитов забора воды из водных источников.…”

Purpose: to analyze water resources scarcity, information on the availability of reclaimed lands and their actual use. Materials and methods: the analysis of the use and distribution of water resources was carried out on the basis of actual data obtained for the period 2016–2020 on land reclamation departments of the Southern Federal District (SFD). The change in the area of actually watered lands and data on the planned and actual water withdrawal in general and for irrigation needs were assessed in comparison with the data for the previous 5 years. Results: the natural shortage of river flow led to a low reservoirs storage and a decrease in the limits of water withdrawal from water sources. The smallest water deficit was observed in 2020 in the river Volga basin (13.4 %), and the largest one – in the main reservoirs of the rivers Don and Kuban (82.6 and 100 %, respectively). The largest total water intake is observed in Kubanmeliovodkhoz and Rostovmeliovodkhoz (Kuban and Rostov Reclamation Water Sector Departments). Their total volume is 4,720.08 million cubic meters, or 74 % of the total withdrawal for all departments of the Southern Federal District (52 and 22 %, respectively). The largest volume of water for irrigation (2.3 and 0.72 cubic km), among the subjects of the Southern Federal District and the largest number of irrigated areas (154.6 and 49.8 thousand hectares) are concentrated in these regions as well. However, the most favorable situation for irrigation has developed in Volgograd Meliovodkhoz (Reclamation Water Sector) Department (the volume of water for irrigation increased by 17 %, irrigated areas – by 12 %) and Adygeya meliovodkhoz (Reclamation Water Sector) Department (the volume of water for irrigation increased by 5 %, and irrigated areas by 36 %). And the most tense situation is in Rostov region. Conclusions: despite the prevailing natural and climatic conditions in spring – summer 2020, which were characterized by high average daily temperatures and lack of precipitation for four months or more, all obligations for irrigation water supply were met in full.
