The data from a two and a half year field study were used to assess the performance of various suspended sediment transport modelling methods. The models selected for this purpose were those proposed by Ackers-White and by Sonnen and these have been assessed following site specific calibrations. A modified version of the Ackers-White model and a rating curve based on a regressional analysis of flowrate versus total suspended solids were also tried. The calibrated verion of the Ackers-White model was selected as giving the best overall accuracy for storm and dry weather conditions. A validation of the selected model using further data for the same site gave approximately 69% of predicted concentrations between 1/2 and 2 times the observed values.
