Forms of Lake Basins in Ukrainian Polissya

Abstract

Statistieal analysis of the complex investigation results of reservoirs in Ukrainian Polissya testify that the most wide spread lakes arc the basins of parabolic and half-elliptical forms. In the process of evolution the changes of forms are directed to increasing the capacity factor. Correlating dependence between the form of the lake basin and degree of filling it with bottom sediments is determined. The form of the basin and the peculiarities of its underwater composition define the formation of the limnosystem in the whole, temperature and gas regimes, and accumulation of bottom sediments, etc. In most cases the conliguration of basins is one of the most significant factors, determined by the limnoproccsscs in reservoirs.
