Abstract—Based on analysis on the existing equations for the site observations that sedimentation rate of ules is closely
sedimentation rate of fine sediment, this study proposes a related to concentration of suspended sediment [1,2]
method to calculate the sedimentation rate of fine suspended

this basis, an empirical equation of sediment sedimentation rate Burt suggests that medians sedimentation rate can be written
