Features of implementation of measures to improve the hydrological regime of the Pshish River in the Kuban water basin

[摘要] The article discusses ways to improve the hydrological regime of the Pshish River in the Kuban water basin. In the context of the progressive shortage of fresh water, especially in the south of Russia, the study of the water resources of the Kuban River basin is of particular relevance. Medium and small rivers are still poorly studied in hydrological terms. At high water levels, the Pshish River and the Krasnodar reservoir are the feeding boundaries for ground water in the protected area, and they are drains at low water levels. When the water levels in the reservoir are less than 29 m (this is the low-water level in the Pshish River in the area of the transverse dam), its influence on the protected area practically ceases, since the coastline of the Krasnodar reservoir recedes from the transverse dam far to the northwest, exposing the previously flooded riverbed. Clearing of flooded riverbeds is proposed to be carried out by the method of roiling. This method is used in reservoirs with the flow, because the essence of it is that muddy sediments are roiled using a floating dredger with water jets and the slurry is not sucked into the dredger and suspended sediments are transported by the flow of water in the bowl of the "dead" area of the reservoir. The use of this method is recommended for economic reasons, since it is 2.4 times cheaper than clearing with the removal of pulp.
