【 摘 要 】

This study considers the possibility of using geometric models in the study of individual elements of hydrological regime in different types of protected shallows in the Upper Volga reservoirs. Three types of models were chosen and verified. The formulas for calculating the bathygraphic curves of geometric figures approximating the beds of protected shallows are determined. Classes with different morphometric characteristics are identified using non-hierarchical cluster analysis for each type of shallows. Model calculations of areas and volumes of shallows are carried out depending on seasonal changes in water level, as well as estimates of thermal content, average monthly water balance and water exchange in the shallows.
