Abstract
The form of a lake basin and the characteristics of its underwater part determine the formation of the entire lake system, temperature and gas regimes, and the accumulation of bottom deposits. Thus, they are necessary typological indicators. Among the important features of a particular water body that play a significant role in the development of its lake ecosystem, there are complex interrelations between the lake basin and its water mass. The shape of the lake basin can be cylindrical, ellipsoidal, parabolic, conical, or complex. In most cases, the basin configuration is one of the most significant factors influencing the limnological processes occurring in the water body. Statistical analysis of the results of comprehensive research on 195 lakes of the Ukrainian Polissya region indicates that parabolic and semi-elliptical basin shapes are the most common. During evolution, the change in shape is directed towards increasing the capacity coefficient. A correlation dependence between the shape of the lake basin and the degree of filling with bottom deposits has been determined.
