2. The Južna Morava basin covers an area of 15,696 km2
Elevation ranges from 300 m to 2169 m
Lenght of Južna Morava river is 316 km
The amount of precipitation ranged from 600 mm to 1300 mm
The Južna Morava has a large number of torrential tributaries

3. Methodology Тhe collected data, obtained from the RHSS, includes daily values of water discharge (Q) and suspended sediment concentration (SSC) at the hydrological station Mojsinje for the period 1958–2007. Non-parametric Мann-Кendall (MK) test Non-parametric Pettit test

4. Results

5. Table 3. The results of the Pettitt test for water discharge (Q), specific runoff (q), suspended sediment transport (Qs), and specific suspended sediment transport (Qss).
Legend: T- trasition year; m u1 - period after the transition year; m u2 - period before the transition year; p - significance level

6. Possible Causes of the Downward Trend in Suspended Sediment Transport
Climate change and anthropogenic impact on the environment
Decrease in precipitation has resulted in a decrease in water discharge and suspended sediment load
Anthropogenic influence- measures of erosion control, changes in land use as a result of negative demographic processes, etc.
