The results showed that: (a) on regression, nonlinear least squares method in establishing rating curves produced significantly better and more efficient suspended sediment rating curves; (b) seasonally clustering the data produced better suspended sediment rating curves; (c) based on statistical and physical relations, suspended sediment load in the catchment followed a clear cyclical seasonal pattern; and (d) the land use and agricultural activities, other than rainfall, had a significant impact on the temporal distribution and variability of the suspended sediment load.
