Influence of the Kattakurgan reservoir on soil cover and hydromorphism process

The article determines the state of soil hydromorphism located around the Kattakurgan Reservoir. It is established that changes in the morphological characteristics of the soil, as well as the presence of bog and gley horizons are manifested at different distances and in different directions. According to the research results, soil hydromorphism is not observed on the eastern, southern and western sides of the reservoir. This is due to the fact that these territories are located 60-68 m above sea level compared to the northern part and are not used in agricultural activities. On the northern side, the situation is the opposite: the lands are below sea level relative to the southern, eastern and western parts. The inlet and outlet channels of the reservoir are located here, as well as the collector and drainage system, which does not work efficiently enough. As a result, there is a constant increase in the groundwater level (at a depth of about 82 cm), which contributes to the development of hydromorphism processes. The influence of the reservoir on the soil cover of the northern side is expressed unevenly: the greatest rise in groundwater is recorded in the northwestern part - up to 3-3.5 km from the reservoir. In the northeastern zone, the influence extends up to 2 km, and in the northern - up to 1.7 km.
