ABSTRACT

ABSTRACT: Statistical analysis was applied to compare mean contents of total phosphorus, iron, manganese, aluminium, calcium and organic matter, as well as pH, in bottom sediments of two Polish reservoirs (Solina and Myczkowce). It proved possible to observe natural spatial differentiation in the chemical compositions of the bottom sediments in different parts of the same reservoir, and also between reservoirs. In the case of such a large body of water as the Solina Reservoir (and despite relatively limited differences in means of land management and utilisation), the influence of the drainage basin on bottom sediments in the zone of the reservoir influenced by river flow was seen to be rather marked.
