Erosion of soils is becoming a serious problem in forested mountain areas where the natural and even the anthropogenic influences are favourable to this process (Flysch substratum, rainfalls, declivity of slopes and tractors and other machines for forest work). The regime of the suspended matter in the basins in the central and eastern parts of the Moravskoslezské Beskydy Mts. - the Upper Ostravice R. (72,96 km2) and in the Lomná R. (70,40 km2) were compared. The results show that the erosional processes in the basin of the Upper Ostravice R are more intensive than in the basin of the Lomná R., due to the prevailance of shales in the substratum of the basin of the Ostravice R.
