The paper is concerned with identifying changes in the time series of discharge (Q), suspended sediment concentration (SSC) and sediment load (Qs) of the Velika Morva River. The catchment area on farthest hydrological profile Ljubičevski most on Velika Morava River is approximately 35496 km2. In this profile were carried out daily measurements of flow and concentration of silt in the period 1967 to 2007. Average perennial transport of suspended sediment is 2,57*106
t (72,4 t/km2/y) and ranged from 0,17*106 t (4,8 t/km2/y) to 10,02*106 t (282,2 t/km2/y). Trends determined for Q, SSC and Qs are statistically obtained using the non-parametric Mann-Kendall test. Results of Mann-Kendall test show that Q has a slight declining trend of annual values which do not show statistical significance. Decline in trendline SSC and Qs is a significant at a level of 0.01. Calculating the standardized regression coefficients, it was found that the relative impact of SSC on sediment load is 3.1 time hig...her than the impact of discharge. For the period 1967-2007 the average dicrease in sediment load at the mouth of the Velika Morava was 3,1 t/km2/y. Decrease in suspended sediment concentrations in recent period can be explained by changes in land use, negative demographic development trends (depopulation of rural areas), carrying out conservation works in the catchment and hydro-technical works in the river bed of the Velika Morava river.
