abstract = "Dynamics of totall dissolved solids (TDS) and suspended sediment concentrations (SSC)
were monitored on the river Nišava at the hydrological station Dimitrovgrad. Water
samples were collected each day in the period from 01.01.2010–31.12.2010. TDS
concentration followed a seasonal pattern imposed by the availability of water, with
higher concentrations recorded in low-flow periods and lower concentration in the highflow period. SSC was extremely variable and dominate mainly with specific high-flow
events. Mean annual discharge (Q=6.68 m3/s, q=13.9 l/s/km2) over the year was 3.3 times
higher than the average for the period of 50 years. In the study period, the annual transport
dissolved load (Qd) was 36962.8 t (specific load Qds=76.7 t/km2/yr) and suspended
sediment load (Qs) was 98861.9 t (specific load Qss=205.1 t/km2/yr). The transport of
dissolved load and suspended sediment load shows temporal variations in different
seasons. The analysis revealed that the maximum loads was transferred during the winter
(Qd=43.3% and Qs=56.8% of the annual transport) and spring season (Qd=37.9% and
Qs=38.9% of the annual transport). A comparative analysis of Q, Qd, and Qs show that
the suspended sediment shows greater variability and exponential pattern of transport.
For instance, 90% of the time was required to export 65% of the total water and
transported 77% of the total dissolved load and only 22% total suspended sediment load.
The most extreme precipitation episodes and extreme temperatures events was recorded
in February 2010. The floods in February contributed by 44.8% of the total Qs transport
over the study period. These findings have important implications for water resource
management in the context of sediments mobilization, erosion, channel management,
water quality and ecological functions.",
