| In this paper, a depth-averaged two-dimensional transport model is introduced, and its error bound is presented as the results of sensitivity analysis. The results show that the calculated SS concentration is highly dependant on Manning roughness coefficient, mixing coefficient. fall velocity. and critical shear stress. On the other hand, water level and dispersion coefficient are proved to be less significant in the variation of SS concentration. Keywords: sensitivity analysis, Manning roughness coefficient, mixing coefficient, fall velocity, critical shear stress, water level, dispersion coefficeint |
