Sažetak
This paper presents processing of measured concentrations of suspended sediment load in three hydrological stations on the Drava river, Croatia. Measurement data were available for discrete moments during 16-year period (1990- 2007) in gauging stations Botovo, Terezino Polje, and Donji Miholjac. The data were provided by the National Hydrometeorological Institute (DHMZ), which carried out the sampling and initial calculations of concentration. Data processing includes only ¨profile¨ measurements where sediment sampling was done on several verticals and at several depths of the discharge profile. Data processing shows adjustment of the theoretical curve of distribution of concentration of values measured at each station. Mathematical concentrations used in further processing were obtained by excluding 5 percent fractiles in measured data. Further, the paper shows the dependence concentration- discharge in the stations, and interdependence of sediment concentrations between the three stations for small, medium and high water flows. Finally, based on the resulting dependence of concentrations between the stations, the estimate is given of concentration of suspended sediment load in the downstream station Belišće.
