Suspended sediment (SS) is one of the important parameters quantifying the degree of water pollution. In order to explore the spatiotemporal variation of the SS in Le’an river catchment, an important sub-catchment of Poyang lake basin, a total of 17 sampling points at rivers were selected for observations. Results show that, the concentration of SS is quite different across the catchment. The average concentration of SS in the upstream of the catchment with forest as the dominant land use, is 6.92mg/L, while the concentration in the downstream with a certain percentage of arable land is 14.39mg/L. The SS concentration shows an increasing trend from the upstream to the downstream, in correlation with the change of land uses. Also there exists a considerable deviation of the SS concentration in different seasons. The concentration in summer is relatively high, while lower in other seasons, with a likely relationship to rainfall events.

Fine Suspended Sediment

The Australian Institute of Marine Science (AIMS) has developed an in situ digital turbidity logger (AIMS River Logger) to record time series of fine suspended sediment concentrations in North Queensland rivers. The loggers use dual LED transmissometers (15 and 85 mm pathlength) to measure in situ turbidity associated with the range of suspended sediment concentrations (0-5 g L-1) encountered in regional rivers. A system of wiper brushes clean the optical surfaces prior to instrument readings. Overlying water depth and temperature are concurrently recorded. Internal batteries provide sufficient power for unattended deployments of 6+ months with readings taken at 30 minute intervals. Records of suspended sediment concentrations in the lower Tully River over three wet seasons (1996, 1997, 2000) are shown in relation to concurrent river discharge. Peaks in suspended sediment concentration coincide with discharge events. During each event, peak sediment concentrations typically occur during the rising stage of the hydrograph, then decline rapidly prior to significant falls in water level. Derived suspended loads during discharge events are generally proportional to the size of the event, though higher responses are recorded during the initial flood event of each wet season.
