Abstract:

Performance of some selected sediment transport formulas was tested using a parameter-sensitivity analysis and a series of numerical experiments with an imaginary channel data. Selection of the sediment transport formulas to be tested is based on a careful review of existing assessments of total sediment discharge formulas found in the literature. Through these analyses, various defects inherent in some transport formulas have been revealed. The result from these analyses can be used, along with those already obtained from direct comparison with measurement, to evaluate existing sediment transport formulas and select more reliable ones.
