Abstract

Sediment transport is the natural phenomenon which is occurred along river stream. Many factors are influencing on this process, but the main parameters are current velocity and flow discharge. The velocity and flow discharge are two river components which intercorrelated each other. Current velocity may cause scouring at the river stream continuously. The materials from scouring process would be become the primary sources of sediment load. There are two sediment load types, suspended load and bed load. The quantity of sediment load that expressed by sediment concentration plays an important part in river morphology changing. This study is focused to assess the sediment concentration affected by current velocity. The sediment samples were taken from Kanor village-Bengawan Solo River during the dry and monsoon seasons. Suspended load samples were taken by suspended trap equipment. River water current was measured by current meter magnetic. This paper is mainly investigated the differences between the quantity of sediment concentration affected by river water current during the dry and monsoon seasons. The investigation results were sediment concentration in milligram per liter (mg/L) and river water current. Based on the data analysis result, the sediment concentrations and current velocities shows the linear correlation. During dry season the sediment concentration and current velocity are lower than in the monsoon season. The highest sediment concentrations were at 0.8 of water depth. This phenomenon is thought be due the effect of particle settling process, so the sediment concentrations are accumulate at the lower point of water column.
