It is well-known that the river sediment regime depends on both production of eroded sediment in the catchment area and the hydrological regime of the river. The functions S(Q) of the Vlasina and the Toplica (Figs. 13 and 14) show that the Vlasina exhibited higher levels of S (even above 10 kg/s), especially in the high-flow range. On the other hand, the torrential nature of this river resulted in higher water discharge and sediment transport rates at high flows. This explained the difference between the sediment transport duration curves of these two rivers, as shown in Fig. 16.
