Suspended sediment concentration and yield in snowmelt flood events in a small lowland river
Results of investigation on suspended sediment delivery from small lowland, agriculturally used catchment of Zagożdżonka River, located in central Poland, during snowmelt periods of 2001-2007 are presented. The study catchment's area, upstream of the well equipped gauging station at Czarna, is 23.4 km2. Suspended sediment concentration and sediment yield has been calculated and analysed for 15 snowmelt flood events. The relationship between suspended sediment concentration and the discharge has been analyzed. It has been found that the relation, in majority of the cases, has the form of clockwise hysteresis, however the existance of other types of hysteresis i.e. anticlockwise and "8" shape, have been also confirmed. Significant relation between suspended sediment yield and runoff volume of snowmelt flood events has been also found.
