Dispersion of the sediment caused by the land use

Abstract

Forty-seven sediment samples from four lacustrine basins were analyzed in order to determine and compare the dispersity of sediments. Twelve were sampled from the Valjevo-mionica basin were more than a half are carbonate sediments, while the rest are marls; thirteen carbonate and marl sediment samples were taken from the Lopare basin; eight samples from Aleksinac basin are marls and oil shales, while fourteen samples from Toplica basin are mainly sandstone, clay and tuffs and marls in smaller portions. Electrical conductivity (EC), pH and elemental composition were measured, while dispersivity index sodium-adsorption ratio (SAR) was calculated from the concentration of cations.
