Abstract

Krasnodar Reservoir is the largest in the North Caucasus artificial reservoir, which has anti-flood and irrigation functions. It is located on the territory of the Krasnodar Territory and the Republic of Adygea. For the period of operation since 1973, the reservoir has undergone notable transformations, reflected in the transformation of the thickets of the reservoir. According to the bathymetric surveys of 2004–2005 and in 2016 an estimation of long-term transformations of the Krasnodar Reservoir in terms of its contours, area, capacity, changes in the bottom surface, and other characteristics was performed. The survey data, followed by the construction of a DEM, made it possible to assess the dynamics of changes in the morphometric indices of the Krasnodar Reservoir that occurred during its operation.

As a result of silting, the reservoir was divided into two reservoirs; the former Tchikskoye reservoir was isolated from the western part of the Krasnodar reservoir by a water jumper and turned into an independent reservoir. According to bathymetric measurements, a continuous decrease in the capacity and area of the Krasnodar reservoir is established with simultaneous overgrowing of shoal with shrub and tree vegetation.

The volume of sedimentation of the Krasnodar reservoir (without an isolated Tchikskoye reservoir with an independent water regime) for 2005–2016 amounted to 83.2 million m³. The direction of transformation leads to a deterioration of the flood control and irrigation functions of the reservoir. The established rates of silting, shrinking area and useful volume will lead to the degradation of the Krasnodar Reservoir in the coming decades.
